CSS values and units - Learn web development
in the following example we have set the color of our heading using a keyword, and the background using the rgb() function: h1 { color: black; background-color: rgb(197,93,
161); } a value in css is a way to define a collection of allowable sub-values.
... to start with, we set
16px as the font size on the <html> element.
... the standard color system available in modern computers is 24 bit, which allows the display of about
16.7 million distinct colors via a combination of different red, green and blue channels with 256 different values per channel (256 x 256 x 256 =
16,777,2

Capabilities, constraints, and settings - Web APIs
for example: let constraints = { width: 1920, height: 1080, aspectratio: 1.777777778 }; mytrack.applyconstraints(constraints); in this case, the constraints indicate that any values are fine for nearly all properties, but that a standard high definition (hd) video size is desired, with the standard
16:9 aspect ratio.
...on(reason) { /* failed to apply constraints; reason is why */ }); } here, after ensuring that the constrainable properties for which matches must be found are supported (width, height, framerate, and facingmode), we set up constraints which request a width no smaller than 640 and no larger than 1920 (but preferably 1920), a height no smaller than 400 (but ideally 1080), an aspect ratio of
16:9 (1.777777778), and a frame rate no greater than 30 frames per second.
... applying constraints the first and most common way to use constraints is to specify them when you call getusermedia(): navigator.mediadevices.getusermedia({ video: { width: { min: 640, ideal: 1920 }, height: { min: 400, ideal: 1080 }, aspectratio: { ideal: 1.7777777778 } }, audio: { samplesize:
16, channelcount: 2 } }).then(stream => { videoelement.srcobject = stream; }).catch(handleerror); in this example, constraints are applied at getusermedia() time, asking for an ideal set of options with fallbacks for the video.

16.png", onclick: removeforwardbutton }); there are more useful examples of this technique in the jetpack wiki's collection of third party modules.
...var tab = require("sdk/tabs/utils").getactivetab(window); if (tab.style.getpropertyvalue('background-color')) { tab.style.setproperty('background-color','','important'); } else { tab.style.setproperty('background-color','rgb(255,255,100)','important'); } } require("sdk/ui/button/action").actionbutton({ id: "highlight-active-tab", label: "highlight active tab", icon: "./icon-
16.png", onclick: highlightactivetab }); security implications the sdk implements a security model in which an add-on only gets to access the apis it explicitly imports via require().
... getservice(ci.nsipromptservice); require("sdk/ui/button/action").actionbutton({ id: "xpcom-example", label: "hello from xpcom", icon: "./icon-
16.png", onclick: function() { promptsvc.alert(null, "my add-on", "hello from xpcom"); } }); it's good practice to encapsulate code which uses xpcom by packaging it in its own module.
... getservice(ci.nsipromptservice); exports.alert = function(title, text) { promptsvc.alert(null, title, text); }; if we save this as "alert.js" in our add-on's lib directory, we can rewrite main.js to use it as follows: require("sdk/ui/button/action").actionbutton({ id: "xpcom-example", label: "hello from xpcom", icon: "./icon-
16.png", onclick: function() { require("./alert").alert("my add-on", "hello from xpcom"); } }); one of the benefits of this is that we can control which parts of the add-on are granted chrome privileges, making it easier to review and secure the code.
Modifying the Page Hosted by a Tab - Archive of obsolete content
here's a simple example: var button = require("sdk/ui/button/action").actionbutton({ id: "style-tab", label: "style tab", icon: "./icon-
16.png", onclick: function() { require("sdk/tabs").activetab.attach({ contentscript: 'document.body.style.border = "5px solid red";' }); } }); to run this example, save an icon file named "icon-
16.png" in add-on's "data" directory.
... for example, if we save the script above under the add-on's data directory in a file called my-script.js: var self = require("sdk/self"); var button = require("sdk/ui/button/action").actionbutton({ id: "style-tab", label: "style tab", icon: "./icon-
16.png", onclick: function() { require("sdk/tabs").activetab.attach({ contentscriptfile: self.data.url("my-script.js") }); } }); you can load more than one script, and the scripts can interact directly with each other.
... // index.js var self = require("sdk/self"); var tabs = require("sdk/tabs"); require("sdk/ui/button/action").actionbutton({ id: "load-several", label: "load several scripts", icon: "./icon-
16.png", onclick: function () { tabs.activetab.attach({ contentscriptfile: [self.data.url('first.js'), self.data.url('second.js')] }); } }); communicating with the content scripts your add-on script and content scripts can't directly access each other's variables or call each other's functions, but they can send each other messages.
...f.port.on("drawborder", function(color) { document.body.style.border = "5px solid " + color; }); in the add-on script, we'll send the content script a "drawborder" message using the object returned from attach(): var self = require("sdk/self"); var tabs = require("sdk/tabs"); var button = require("sdk/ui/button/action").actionbutton({ id: "style-tab", label: "style tab", icon: "./icon-
16.png", onclick: function() { var worker = tabs.activetab.attach({ contentscriptfile: self.data.url("my-script.js") }); worker.port.emit("drawborder", "red"); } }); the drawborder message isn't a built-in message, it's one that this add-on defines in the port.emit() call.

although the exact size will vary depending on the theme being used, the size of menu item images should generally be around

... the top
16px square is the icon in normal state the bottom part in hovered state.
...hence, -moz-image-region is not applied to the menu itself, but one level lower: <menuitem id="add-bookmark" class="menuitem-iconic" label="add bookmark" image="addbookmark.png"/> #add-bookmark { list-style-image: url('addbookmark.png'); } #add-bookmark .menu-iconic-icon { -moz-image-region: rect(0px,

Using the Right Markup to Invoke Plugins - Archive of obsolete content

Fundamental text and font styling - Learn web development
this all starts with the root element of the entire document — <html> — the font-size of which is set to
16px as standard across browsers.
... any paragraph (or another element that doesn't have a different size set by the browser) inside the root element will have a final size of
16 px.
... <!-- document base font-size is
16px --> <article> <!-- if my font-size is 1.5em --> <p>my paragraph</p> <!-- how do i compute to 20px font-size?
... a simple sizing example when sizing your text, it is usually a good idea to set the base font-size of the document to 10 px, so that then the maths is a lot easier to work out — required (r)em values are then the pixel font size divided by 10, not
16.
Styling lists - Learn web development
eese with a higher-than-usual melting point, usually made from goat/sheep milk.</dd> <dt>green salad</dt> <dd>that green healthy stuff that many of us just use to garnish kebabs.</dd> </dl> if you go to the live example now and investigate the list elements using browser developer tools, you'll notice a couple of styling defaults: the <ul> and <ol> elements have a top and bottom margin of
16px (1em) and a padding-left of 40px (2.5em.) the list items (<li> elements) have no set defaults for spacing.
... the <dl> element has a top and bottom margin of
16px (1em), but no padding set.
... the <dd> elements have margin-left of 40px (2.5em.) the <p> elements we've included for reference have a top and bottom margin of
16px (1em), the same as the different list types.
...we are using a size of 1.6rem (
16px), which fits very nicely with the 20px padding we've allowed for the bullet to sit inside —
16px plus 4px of space between the bullet and the list item text works well.

HTML parser threading
once a unicode decoder has been set up, dodataavailable passes the byte data to the decoder whose output is accumulated into a linked list of nshtml5owningutf
16buffer objects.
... nshtml5owningutf
16buffer objects are then passed to the tokenizer in sequence by the parseavailabledata() method.
...the speculation object has a queue of tree ops (into which the tree builder will now flush ops to instead of the tree op stage), an owning reference to the nshtml5owningutf
16buffer that contains the starting point of the speculation, an index into the nshtml5owningutf
16buffer defining the exact starting point within the buffer, the line number of the tokenizer at that point and a snapshot of the tree op state.
...if there is data in document.write() input after a an external script (or any data at all if a previous document.write() call has contained an external script and blocked the parser), the data is left in a linked list of nshtml5owningutf

WindowOrWorkerGlobalScope.btoa() - Web APIs
in javascript strings are represented using the utf-
16 character encoding: in this encoding, strings are represented as a sequence of
16-bit (2 byte) units.
...so if you pass a string into btoa() containing characters that occupy more than one byte, you will get an error, because this is not considered binary data: const ok = "a"; console.log(ok.codepointat(0).tostring(
16)); // 61: occupies < 1 byte const notok = "✓" console.log(notok.codepointat(0).tostring(
16)); // 2713: occupies > 1 byte console.log(btoa(ok)); // yq== console.log(btoa(notok)); // error if you need to encode unicode text as ascii using btoa(), one option is to convert the string such that each
16-bit unit occupies only one byte.
... for example: // convert a unicode string to a string in which // each
16-bit unit occupies only one byte function tobinary(string) { const codeunits = new uint
16array(string.length); for (let i = 0; i < codeunits.length; i++) { codeunits[i] = string.charcodeat(i); } return string.fromcharcode(...new uint8array(codeunits.buffer)); } // a string that contains characters occupying > 1 byte const mystring = "☸☹☺☻☼☾☿"; const converted = tobinary(mystring); const encoded = btoa(converted); console.log(encoded); // ocy5jjomoyy8jj4mpyy= if you do this, of course you'll have to reverse the conversion on the decoded string: function frombinary(binary) { const bytes = new uint8array(binary.length); for (let i = 0; i < bytes.length; i++) { bytes[i...

Mastering Wrapping of Flex Items - CSS: Cascading Style Sheets
in the next example i have ten items all with a flex-basis of
160px and the ability to grow and shrink.
... once the first row gets to a point where there is not enough space to place another
160 pixel item, a new flex line is created for the items and so on until all of the items are placed.
... as the items can grow, they will expand larger than
160 px in order to fill each row completely.
...the following live sample uses css grid layout to create a layout that has as many columns of at least
160 pixels as will fit, distributing the extra space between all columns.

the prototype of the poll method is print
16 poll_method(prfiledesc *fd, print
16 in_flags, print
16 *out_flags); the purpose of the poll method is to allow a layer to modify that flags that will ultimately be used in the call to the underlying network transport's select (or equivalent) function, and to indicate that a layer is already able to make progress in the manner suggested by the polling flags.
...declare two print
16 variables to receive the return value and the out_flags output argument of the poll method.

javascript strings are utf-

16 code units as placeholders for uint8 numbers is that as web applications become more and more powerful (adding features such as audio and video manipulation, access to raw data using websockets, and so forth) it has become clear that there are times when it would be helpful for javascript code to be able to quickly and easily manipulate raw binary data.

16- (aka half float) and 32-bit floating-point components.
... constants ext.half_float_oes half floating-point type (
16-bit).

RTCIceCandidate.candidate - Web APIs

168.0.56 44323 typ host the corresponding candidate string's value will be "candidate:4234997325 1 udp 2043278322 192.
168.0.56 44323 typ host".
...the complete list of attributes for this example candidate is: foundation = 4234997325 component = "rtp" (the number 1 is encoded to this string; 2 becomes "rtcp") protocol = "udp" priority = 2043278322 ip = "192.
168.0.56" port = 44323 type = "host" example in this example, we see a function which receives as input an sdp string containing an ice candidate received from the remote peer during the signaling process.
... this example could be simplified somewhat; you may more often see the code look something like this, taking advantage of more advanced ecmascript 20
16 features: let handlenewicecandidate = candidatesdp => mypeerconnection.addicecandidate(new rtcicecandidate(candidatesdp)); specifications specification status comment webrtc 1.0: real-time communication between browsersthe definition of 'rtcicecandidate.candidate' in that specification.

16 working draft.
... this value was in the rtcsignalingstate enum (and therefore found by reading the value of the signalingstate) property until the may 13, 20
16 draft of the specification.
... note: this value moved into the rtcpeerconnectionstate enum in the may 13, 20
16 draft of the specification, as it reflects the state of the rtcpeerconnection, not the signaling connection.

Basic concepts behind Web Audio API - Web APIs
say you've got a
16 x
16 image, but you want it to fill a 32x32 area.
...the left and right channels are stored like this: llllllllllllllllrrrrrrrrrrrrrrrr (for a buffer of
16 frames) this is very common in audio processing: it makes it easy to process each channel independently.
... the alternative is to use an interleaved buffer format: lrlrlrlrlrlrlrlrlrlrlrlrlrlrlrlr (for a buffer of
16 frames) this format is very common for storing and playing back audio without much processing, for example a decoded mp3 stream.
Web Authentication API - Web APIs
note that it is absolutely critical that the challenge be a buffer of random information (at least
16 bytes) and it must be generated on the server in order to ensure the security of the registration process.

A re-introduction to JavaScript (JS tutorial) - JavaScript
unless you're certain of your string format, you can get surprising results on those older browsers: parseint('010'); // 8 parseint('0x10'); //
16 here, we see the parseint() function treat the first string as octal due to the leading 0, and the second string as hexadecimal due to the leading "0x".
... you can also use the unary + operator to convert values to numbers: + '42'; // 42 + '010'; // 10 + '0x10'; //
16 a special value called nan (short for "not a number") is returned if the string is non-numeric: parseint('hello', 10); // nan nan is toxic: if you provide it as an operand to any mathematical operation, the result will also be nan: nan + 5; // nan you can test for nan using the built-in isnan() function: isnan(nan); // true javascript also has the special values infinity and -infinity:...
...more accurately, they are sequences of utf-
16 code units; each code unit is represented by a
16-bit number.

List Open Tabs - Archive of obsolete content

16.png".
...the script adds a red border to the tab's document: require("sdk/ui/button/action").actionbutton({ id: "list-tabs", label: "list tabs", icon: "./icon-
16.png", onclick: listtabs }); function listtabs() { var tabs = require("sdk/tabs"); for (let tab of tabs) runscript(tab); } function runscript(tab) { tab.attach({ contentscript: "document.body.style.border = '5px solid red';" }); } learning more to learn more about working with tabs in the sdk, see the tabs api reference.

16.png", onclick: function() { encoded = base64.btoa("hello"); console.log(encoded); decoded = base64.atob(encoded); console.log(decoded); } }); to run this example you'll also have to have an icon file named "icon-
16.png" saved in your add-ons "data" directory.
... at this point your add-on ought to look like this: /base64 /data icon-
16.png package.json readme.md index.js base64.js /test test-base64.js now execute jpm --verbose test from the add-on's root directory.

...so you could hide the actual from input using something like this: input[type="file"] { height: 0; padding: 0; opacity: 0; } and then style the label to act like a button, which when pressed will open the file picker as expected: label[for="file"] { box-shadow: 1px 1px 3px #ccc; background: linear-gradient(to bottom, #eee, #ccc); border: 1px solid rgb(

NSPR Types
examples of the use of these types: in dowhim.h: pr_extern( void ) dowhatimean( void ); static void pr_callback rootfunction(void *arg); in dowhim.c: pr_implement( void ) dowhatimean( void ) { return; }; prthread *thread = pr_createthread(..., rootfunction, ...); algebraic types nspr provides the following type definitions with unambiguous bit widths for algebraic operations: 8-,
16-, and 32-bit integer types 64-bit integer types floating-point number type for convenience, nspr also provides type definitions with platform-dependent bit widths: native os integer types 8-,
16-, and 32-bit integer types signed integers print8 print

... note winsock.h defines h_addrtype and h_length as a
16-bit field, whereas other platforms treat it as a 32-bit field.
PRUnichar
an unsigned

MediaTrackSettings.sampleSize - Web APIs
the most commonly used sample size for many years now is
16 bits per sample, which was used for cd audio among others.
...for example,
16-bit stereo audio requires (
16/8)*2 or 4 bytes per sample.
MediaTrackSettings - Web APIs
cd-quality audio, for example, is
16-bit, so this value would be
16 in that case.
...common values include 1.3333333333 (for the classic television 4:3 "standard" aspect ratio, also used on tablets such as apple's ipad), 1.7777777778 (for the
16:9 high-definition widescreen aspect ratio), and 1.6 (for the
16:10 aspect ratio common among widescreen computers and tablets).

Refcount tracing and balancing
you may use an object's serial number with the following variable to further restrict the reference count tracing: xpcom_mem_log_objects set this variable to a comma-separated list of object serial number or ranges of serial number, e.g., 1,37-42,73,
165 (serial numbers start from 1, not 0).

Introduction to NSPR
some operating systems cannot be made preemptable (for example, mac os and win
16).
Logging
logging is not compiled in for the win
16 platform.
PRExplodedTime
syntax #include <prtime.h> typedef struct prexplodedtime { print32 tm_usec; print32 tm_sec; print32 tm_min; print32 tm_hour; print32 tm_mday; print32 tm_month; print
16 tm_year; print8 tm_wday; print
16 tm_yday; prtimeparameters tm_params; } prexplodedtime; description the prexplodedtime structure represents clock/calendar time.
PRIntn
it is guaranteed to be at least
16 bits, though various architectures may define it to be wider (for example, 32 or even 64 bits).
PRNetAddr
syntax #include <prio.h> union prnetaddr { struct { pruint
16 family; char data[14]; } raw; struct { pruint
16 family; pruint
16 port; pruint32 ip; char pad[8]; } inet; #if defined(_pr_inet6) struct { pruint
16 family; pruint
16 port; pruint32 flowinfo; pripv6addr ip; } ipv6; #endif /* defined(_pr_inet6) */ }; typedef union prnetaddr prnetaddr; fields the structure has the following fields: family address family: pr_af_inet|pr_af_inet6 for raw.family, pr_af_inet for inet.family, pr_af_inet6 for ipv6.family.

there are four equality algorithms in es2015: abstract equality comparison (==) strict equality comparison (===): used by array.prototype.indexof, array.prototype.lastindexof, and case-matching samevaluezero: used by %typedarray% and arraybuffer constructors, as well as map and set operations, and also string.prototype.includes and array.prototype.includes since es20
16 samevalue: used in all other places javascript provides three different value-comparison operations: === - strict equality comparison ("strict equality", "identity", "triple equals") == - abstract equality comparison ("loose equality", "double equals") object.is provides samevalue (new in es2015).
Expressions and operators - JavaScript
so, when the bitwise operators are applied to these values, the results are as follows: bitwise operator examples expression result binary description 15 & 9 9 1111 & 1001 = 1001 15 | 9 15 1111 | 1001 = 1111 15 ^ 9 6 1111 ^ 1001 = 0110 ~15 -
16 ~ 0000 0000 ... 0000 1111 = 1111 1111 ... 1111 0000 ~9 -10 ~ 0000 0000 ... 0000 1001 = 1111 1111 ... 1111 0110 note that all 32 bits are inverted using the bitwise not operator, and that values with the most significant (left-most) bit set to 1 represent negative numbers (two's-complement representation).
Functions - JavaScript
for example, the function square could have been defined as: const square = function(number) { return number * number } var x = square(4) // x gets the value
16 however, a name can be provided with a function expression.

Method definitions - JavaScript
const obja = { method() {} } new obja.method // typeerror: obj.method is not a constructor const objb = { * g() {} } new objb.g // typeerror: obj.g is not a constructor (changed in es20
16) examples simple test case const obj = { a: 'foo', b() { return this.a } }; console.log(obj.b()) // "foo" computed property names the shorthand syntax also supports computed property names.
Array.prototype.forEach() - JavaScript
a[1] = 5 // a[3] = 9 using thisarg the following (contrived) example updates an object's properties from each entry in the array: function counter() { this.sum = 0 this.count = 0 } counter.prototype.add = function(array) { array.foreach((entry) => { this.sum += entry ++this.count }, this) // ^---- note } const obj = new counter() obj.add([2, 5, 9]) obj.count // 3 obj.sum //
16 since the thisarg parameter (this) is provided to foreach(), it is passed to callback each time it's invoked.

Web Performance
to understand how to improve performance and perceived performance, it helps to understand how the browser works.recommended web performance timings: how long is too long?there are no clear set rules as to what constitutes a slow pace when loading pages, but there are specific guidelines for indicating content will load (1 second), idling (50ms), animating (
16.7s) and responding to user input (50 to 200ms).the business case for web performanceyou know web performance is important, but how do you convince clients and management to invest in performance and make it a priority.
