@namespace - CSS: Cascading Style Sheets
@namespace is an at-rule that defines xml namespaces to be used in a css style sheet. syntax /* default namespace */ @namespace url(xml-namespace-url); @namespace "xml-namespace-url"; /* prefixed namespace */ @namespace prefix url(xml-namespace-url); @namespace prefix "xml-namespace-url"; description the defined namespaces can be used to restrict the universal, type, and attribute selectors to only select elements within that namespace. the @namespace rule is generally only useful when dealing with documents containing multiple namespaces—such as html5 with inline svg or mathml, or xml that mixes multiple vocabularies. any @namespace rules must follow all @charset and @import rules, and precede all other at-rules and style declarations in a style sheet. ...

Standard metadata names - HTML: Hypertext Markup Language
the <meta> element can be used to provide document metadata in terms of name-value pairs, with the name attribute giving the metadata name, and the content attribute giving the value. standard metadata names defined in the html specification the html specification defines the following set of standard metadata names: application-name: the name of the application running in the web page. note: browsers may use this to identify the application. it is different from the <title> element, which usually contain the application name, but may also contain information like the document name or a status. simple web pages shouldn't define an application-name. author: the name of the document's author. description: a short and accurate summary of the content of the page. se...

Case Sensitivity in class and id Names - Archive of obsolete content
summary: although css is itself case-insensitive, class and id names are defined to be case-sensitive in html 4.01. find out how this wrinkle can affect your site design and best practices to avoid any problems. in the authoring of both css and javascript/dom (otherwise known as dhtml) routines, it is a near-certainty that class and id names will be used to identify elements. we have discovered, however, that many authors are running into trouble with class and id names because they're used to the bugs of browsers that don't fully support open standards. the most common case is where the name uses different case in the document source than is found in the css or javascript. for example, there might be this css: p.warning {color: red; background: yellow;} ...coupled with this html: <...

...tion will have neither red text nor a yellow background. as far as netscape 6 is concerned, warning and warning are two different identifiers, because html 4.01 defines class and id names to be case-sensitive. (for a detailed explanation of what html 4.01 says, see the following section, "why so case-sensitive?") the only way to avoid this particular problem is to make sure that your class and id names have consistent case throughout the entire document, and with respect to your css and javascript. it is also important to avoid using class or id names which are a case-insensitive match within the same document. ...

NamedNodeMap - Web APIs
the namednodemap interface represents a collection of attr objects. objects inside a namednodemap are not in any particular order, unlike nodelist, although they may be accessed by an index as in an array. a namednodemap object is live and will thus be auto-updated if changes are made to its contents internally or elsewhere. although called namednodemap, this interface doesn't deal with node objects but with attr objects, which were originally a specialized class of node, and still are in some implementations. properties this interface doesn't inherit any property. namednodemap.length read only returns the amount of objects in the map. methods this interface doesn't inherit any method. namednodemap.getnameditem() returns a attr, corresponding to the given name. ...

Underscores in class and ID Names - Archive of obsolete content
jor display problems in multiple browsers. learn why this is so, and how to keep your sites from being bitten by this problem. this technical note examines the use of underscores in css, and why they should be generally avoided in most circumstances. it is a fairly common practice in many programming languages to use the underscore character (_) in the place of a "space" in variable and function names. for example, a function whose job is to "get the length of a string" might be called get_string_length, and a variable representing the number of people who voted republican might be voted_republican. given this fact, authors who write css often attempt to employ the underscore in a similar fashion when creating class and id names. this should not be done. although underscores are, as of this ...

Advanced Svelte: Reactivity, lifecycle, accessibility - Learn web development
erates the required javascript to update only the parts of the dom that need to be updated. this approach usually generates optimal javascript code with minimal overhead, but it also has its limitations. sometimes svelte cannot detect changes to variables being watched. remember that to tell svelte that a variable has changed, you have to assign it a new value. a simple rule of thumb is that the name of the updated variable must appear on the left hand side of the assignment. for example, in the following piece of code: const foo = obj.foo foo.bar = 'baz' svelte won't update references to obj.foo.bar, unless you follow it up with obj = obj. that's because svelte can't track object references, so we have to explicitly tell it that obj has changed by issuing an assignment. note: if foo is ...

es and inheritance in a class-based language, you create a hierarchy of classes through the class definitions. in a class definition, you can specify that the new class is a subclass of an already existing class. the subclass inherits all the properties of the superclass and additionally can add new properties or modify the inherited ones. for example, assume the employee class includes only the name and dept properties, and manager is a subclass of employee that adds the reports property. in this case, an instance of the manager class would have all three properties: name, dept, and reports. javascript implements inheritance by allowing you to associate a prototypical object with any constructor function. so, you can create exactly the employee — manager example, but you use slightly diff...

Microformats - HTML: Hypertext Markup Language
eviated μf) are standards used to embed semantics & structured data in html, and provide an api to be used by search engines, aggregators, and other tools. these minimal patterns of html are used for marking up entities that range from fundamental to domain-specific information, such as people, organizations, events, and locations. microformats use supporting vocabularies to describe objects and name-value pairs to assign values to their properties. the properties are carried in class attributes that can be added to any html element, while the data values re-use html element content and semantic attributes. microformats2 is an update to microformats that provides a simpler way of annotating html structured syntax & vocabularies than previous approaches of using rdfa and microdata which requir...
...ing new attributes. microformats are supported by all major search engines. search engines benefit greatly from direct access to this structured data because it allows them to understand the information on web pages and provide more relevant results to users. in addition to being machine-readable, their format is designed to be easily read by humans. to create a microformats object, h-* class names are used in the class attribute. to add a property to an object, the p-*, u-*, dt-*, e-* class names are used on one of the object's descendants. there are open source parsing libraries for most languages for microformats2. how microformats work an author of a webpage can add microformats to their html. for example if they wanted to identify themselves they could use an h-card such as: htm...

Storing the information you need — Variables - Learn web development
to access this tool). what is a variable? a variable is a container for a value, like a number we might use in a sum, or a string that we might use as part of a sentence. but one special thing about variables is that their contained values can change. let's look at a simple example: <button>press me</button> const button = document.queryselector('button'); button.onclick = function() { let name = prompt('what is your name?'); alert('hello ' + name + ', nice to see you!'); } in this example pressing the button runs a couple of lines of code. the first line pops a box up on the screen that asks the reader to enter their name, and then stores the value in a variable. the second line displays a welcome message that includes their name, taken from the variable value. to understand why ...
...ines of code. the first line pops a box up on the screen that asks the reader to enter their name, and then stores the value in a variable. the second line displays a welcome message that includes their name, taken from the variable value. to understand why this is so useful, let's think about how we'd write this example without using a variable. it would end up looking something like this: let name = prompt('what is your name?'); if (name === 'adam') { alert('hello adam, nice to see you!'); } else if (name === 'alan') { alert('hello alan, nice to see you!'); } else if (name === 'bella') { alert('hello bella, nice to see you!'); } else if (name === 'bianca') { alert('hello bianca, nice to see you!'); } else if (name === 'chris') { alert('hello chris, nice to see you!'); } // ... ...

Microdata DOM API - Web APIs
in some browsers for a long time. nowadays, they have been abandoned and removed from all browsers and are therefore deprecated. you can't use them anymore and this document is kept as information only. microdata becomes even more useful when scripts can use it to expose information to the user, for example offering it in a form that can be used by other applications. the document.getitems(typenames) method provides access to the top-level microdata items. it returns a nodelist containing the items with the specified types, or all types if no argument is specified. each item is represented in the dom by the element on which the relevant itemscope attribute is found. these elements have their element.itemscope idl attribute set to true. the type(s) of items can be obtained using the element.

Using Web Workers - Web APIs

Grammar and types - JavaScript

(for more details, see this blog post.) you can also use the unicode escape sequences as characters in identifiers. some examples of legal names are number_hits, temp99, $credit, and _name. declaring variables you can declare a variable in two ways: with the keyword var. for example, var x = 42. this syntax can be used to declare both local and global variables, depending on the execution context. with the keyword const or let. for example, let y = 13. this syntax can be used to declare a block-scope local variable.

Introduction to events - Learn web development
e.backgroundcolor = rndcol; } the onclick property is the event handler property being used in this situation. it is essentially a property like any other available on the button (e.g. btn.textcontent, or btn.style), but it is a special type — when you set it to be equal to some code, that code is run when the event fires on the button. you could also set the handler property to be equal to a named function name (like we saw in build your own function). the following works just the same: const btn = document.queryselector('button'); function bgchange() { const rndcol = 'rgb(' + random(255) + ',' + random(255) + ',' + random(255) + ')'; document.body.style.backgroundcolor = rndcol; } btn.onclick = bgchange; there are many different event handler properties available. let's experimen...

Mozilla DOM Hacking Guide
e js engine asks xpconnect to search for the relevant c++ method to call. for example, when we ask for |document.getelementbyid("myid");|, xpconnect will find that |document| is a property of the window object, so it will look on the interface nsidomwindow, and it will find the getdocument() method. the return value of getdocument() is a nsidomdocument. so xpconnect will then try to find a method named getelementbyid() on the nsidomdocument interface. and indeed it will find it, and thus call it. this is the schema used most of the time when using w3c dom objects and methods. it is however different for some dom level 0 objects and methods. i'll take two very different examples. the first one is the window.location object (the same holds true for document.location, actually). we can change th...

fallback value if the value you specify for the type attribute is unknown by the browser (for example if you specify type="color" and the browser doesn't support native color pickers). note: you can find examples of all the single line text field types on github at single-line-text-fields.html (see it live also). here is a basic single line text field example: <input type="text" id="comment" name="comment" value="i'm a text field"> single line text fields have only one true constraint: if you type text with line breaks, the browser removes those line breaks before sending the data to the server. the following screenshot shows default, focused and disabled text input types in firefox 71 and safari on macos and in chrome 79 and edge 18 on windows 10. note: html5 enhanced the basic ori...
... html5 enhanced the basic original single line text field by adding special values for the type attribute that enforce specific validation constraints and other features, for example specific to entering urls or numbers. we'll cover those in the next article, the html5 input types. password field one of the original input types was the password text field type: <input type="password" id="pwd" name="pwd"> the password value doesn't add any special constraints to the entered text, but it does obscure the value entered into the field (e.g. with dots or asterisks) so it can't be easily read by others. keep in mind this is just a user interface feature; unless you submit your form securely, it will get sent in plain text, which is bad for security — a malicious party could intercept your da...
...s invisible to the user, but is still sent to the server along with the rest of the form data once submitted — for example you might want to submit a timestamp to the server stating when an order was placed. because it is hidden, the user can not see nor intentionally edit the value, it will never receive focus, and a screen reader will not notice it either. <input type="hidden" id="timestamp" name="timestamp" value="1286705410"> if you create such an element, it's required to set its name and value attributes. the value can be dynamically set via javascript. the hidden input type should not have an associated label. other text input types, like search, url, and tel, were added with html5. those will be covered in the next tutorial, html5 input types. checkable items: checkboxes and rad...

DMD
a heap profiler within firefox. it has four modes. "dark matter" mode. in this mode, dmd tracks the contents of the heap, including which heap blocks have been reported by memory reporters. it helps us reduce the "heap-unclassified" value in firefox's about:memory page, and also detects if any heap blocks are reported twice. originally, this was the only mode that dmd had, which explains dmd's name. this is the default mode. "live" mode. in this mode, dmd tracks the current contents of the heap. you can dump that information to file, giving a profile of the live heap blocks at that point in time. this is good for understanding how memory is used at an interesting point in time, such as peak memory usage.

JavaScript-DOM Prototypes in Mozilla

JNI.jsm

Introduction to XUL - Archive of obsolete content
figurable, downloadable chrome, meaning that the arrangement and even presence or absence of controls in the main window is not hardwired into the application, but loaded from a separate ui description. in fact, most of mozilla's windows (and dialogs) will be described using this mechanism. xul (pronounced "zool," as if that spelling helped any, and short for "xml user interface language") is our name for the language in which these ui descriptions are built. window chrome is displayed and managed by the same layout engine that manages html content in the browser. ui descriptions, then, look a great deal like html 4. xul is an application of xml. in fact, it is just xml with specific meaning defined for a few element types, and into which html can be scattered. terms "xpfe" is the term mozi...
