Relationship of flexbox to other layout methods - CSS: Cascading Style Sheets
te: css versions 1 and 2 were a single monolithic specification where all of css was defined in one large document. as css became a more feature rich language, maintaining one huge specification became problematic, with different parts of css moving on at different speeds. css was therefore modularised, and the various css specifications are different modules that make up css today. these modules relate to each other, and are at different stages of development. the box alignment module for many people the first reason they start to look at flexbox is because of the ability to properly align flex items inside a flex container. flexbox provides access to properties that allow the alignment of items on their cross axis and justification of items on the main axis. these properties started lif...
...box spec is not held up by box alignment, which has to detail these methods for all layout types. there is a note in the flexbox spec stating that in the future, once it is completed, the definitions in box alignment level 3 will supersede those of flexbox: "note: while the alignment properties are defined in css box alignment [css-align-3], flexible box layout reproduces the definitions of the relevant ones here so as to not create a normative dependency that may slow down advancement of the spec. these properties apply only to flex layout until css box alignment level 3 is finished and defines their effect for other layout modes. additionally, any new values defined in the box alignment module will apply to flexible box layout; in otherwords, the box alignment module, once completed, will...
...nd then placing items into them. in flexbox, while you create a flex container and set the direction at that level, any control over item sizing needs to happen on the items themselves. in some cases you could happily use either layout method, but as you become confident with both you will find each one suiting different layout needs, and you will end up with both methods in your css. there is rarely a right or wrong answer. as a rule of thumb, if you are adding widths to flex items in order to make items in one row of a wrapped flex container line up with the items above them you really want two-dimensional layout. in this case it is likely that the component would be better laid out using css grid layout. it isn't the case that you should use flexbox for small components and grid layout f...
... out using css grid layout. it isn't the case that you should use flexbox for small components and grid layout for larger ones; a tiny component can be two dimensional, and a large layout can be represented better with layout in one dimension. try things out — we have a choice in layout method for the first time, so take advantage of it. for more comparisons of grid and flexbox see the article relationship of grid layout to other layout methods. this article details many of the ways that grid layout differs from flex layout, and demonstrates some of the extra functionality you get when using grid layout such as layering of items on the grid. this may also help in your decision as to which layout method to use. flexbox and display: contents the contents value of the display property is a ...

Asynchronous - MDN Web Docs Glossary: Definitions of Web-related terms

...tware communicates asynchronously, a program may make a request for information from another piece of software (such as a server), and continue to do other things while waiting for a reply. for example, the ajax (asynchronous javascript and xml) programming technique—now usually simply "ajax", even though json is usually used rather than xml in modern applications—is a mechanism that requests relatively small amounts of data from the server using http, with the result being returned when available rather than immediately. software design asynchronous software design expands upon the concept by building code that allows a program to ask that a task be performed alongside the original task (or tasks), without stopping to wait for the task to complete. when the secondary task is comple...

HTML - MDN Web Docs Glossary: Definitions of Web-related terms
html (hypertext markup language) is a descriptive language that specifies webpage structure. brief history in 1990, as part of his vision of the web, tim berners-lee defined the concept of hypertext, which berners-lee formalized the following year through a markup mainly based on sgml. the ietf began formally specifying html in 1993, and after several drafts released version 2.0 in 1995. in 1994 berners-lee founded the w3c to develop the web. in 1996, the w3c took over the html work and published the html 3.2 recommendation a year later. html 4.0 was released in 1999 and became an iso standard in 2000. at that time, the w3c nearly abandoned html in favor of xhtml, prompting the founding of an independent group called whatwg in 2004. thanks to whatwg, work on html5 continued: the two organ...

Ajax - MDN Web Docs Glossary: Definitions of Web-related terms
initially stood for asynchronous javascript and xml, is a programming practice of building complex, dynamic webpages using a technology known as xmlhttprequest. ajax allows you to update parts of the dom of an html page instead without the need for a full page refresh. ajax also lets you work asynchronously, meaning your code continues to run while the targeted part of your web page is trying to reload (compared to synchronously, which blocks your code from running until that part of your page is done reloading). with interactive websites and modern web standards, ajax is gradually being replaced by functions within javascript frameworks and the official fetch api standard. ...

Block cipher mode of operation - MDN Web Docs Glossary: Definitions of Web-related terms
ifies how a block cipher should be used to encrypt or decrypt messages that are longer than the block size. most symmetric-key algorithms currently in use are block ciphers: this means that they encrypt data a block at a time. the size of each block is fixed and determined by the algorithm: for example aes uses 16-byte blocks. block ciphers are always used with a mode, which specifies how to securely encrypt messages that are longer than the block size. for example, aes is a cipher, while ctr, cbc, and gcm are all modes. using an inappropriate mode, or using a mode incorrectly, can completely undermine the security provided by the underlying cipher. ...

Cipher - MDN Web Docs Glossary: Definitions of Web-related terms
ach algorithm is judged against known classes of attacks. ciphers operate two ways, either as block ciphers on successive blocks, or buffers, of data, or as stream ciphers on a continuous data flow (often of sound or video). they also are classified according to how their keys are handled: symmetric key algorithms use the same key to encode and decode a message. the key also must be sent securely if the message is to stay confidential. asymmetric key algorithms use a different key for encryption and decryption. ...

Cipher suite - MDN Web Docs Glossary: Definitions of Web-related terms
a cipher suite is a combination of a key exchange algorithm, authentication method, bulk encryption cipher, and message authentication code. in a cryptosystem like tls, the client and server must agree on a cipher suite before they can begin communicating securely. a typical cipher suite looks like ecdhe_rsa_with_aes_128_gcm_sha256 or ecdhe-rsa-aes128-gcm-sha256, indicating: ecdhe (elliptic curve diffie-hellman ephemeral) for key exchange rsa for authentication aes-128 as the cipher, with galois/counter mode (gcm) as the block cipher mode of operation sha-256 as the hash-based message authentication code (hmac) learn more mozilla recommended cipher suite choices for tls ...

Getting Started Guide
; the getting started guide is short. introduction what is nscomptr? nscomptr is a tool to help prevent leaks. nscomptr is a "smart pointer". it is a template class that acts, syntactically, just like an ordinary pointer in c or c++, i.e., you can apply * or -> to it to "get to" what it points at. nscomptr is smart in that, unlike a raw c++ pointer to an xpcom object, nscomptr manages addref, release, and queryinterface for you. nscomptr is defined in the source files: xpcom/base/nscomptr.h xpcom/base/nscomptr.cpp ...though you probably don't want to look in there, just yet. with nscomptr, you can write code that is shorter, cleaner, clearer, and safer, than you can with raw xpcom interface pointers. xpcom basics: ownership and reference counting this is a quick refresher on some...

able to use an nscomptr. an nscomptr is the exact same size and shape as a raw xpcom interface pointer. it can be used as a member variable without introducing bloat. most of the work of being an owning reference can be done in the constructor, destructor, and assignment operators of nscomptr. whenever you `point' the nscomptr at a different xpcom object (by assignment or initialization), it must release its old value, if any, and addref the new. at its own destructor time it must release as well. nscomptr only does exactly the work you would have done, if you always remembered to do the right thing. safety features type safeguards it is an invariant of nscomptr that it holds the xpcom-correct interface pointer for it's underlying type. for example, an nscomptr<nsifoo> will always hold the po...

Anatomy of a video game - Game development
rame model is implemented in something called a main loop. if your game loops based on time then this will be its authority that your simulations will adhere to. but it might not need per-frame control. your game loop might be similar to the find the differences example and base itself on input events. it might require both input and simulated time. it might even loop based on something else entirely. modern javascript — as described in the next sections — thankfully makes it easy to develop an efficient, execute-once-per-frame main loop. of course, your game will only be as optimized as you make it. if something looks like it should be attached to a more infrequent event then it is often a good idea to break it out of the main loop (but not always). building a main loop in javascript ...

Using the Browser API

Power profiling overview
being executed. the other states have higher numbers and reflect increasing deeper idle states. the deeper an idle state is, the less power it uses, but the longer it takes to wake up from. note: the acpi standard specifies four states, c0, c1, c2 and c3. intel maps these to processor-specific states such as c0, c1, c2, c6 and c7. and many tools report c-states using the latter names. the exact relationship is confusing, and chapter 13 of the intel optimization manual has more details. the important thing is that c0 is always the active state, and for the idle states a higher number always means less power consumption. the other thing to note about c-states is that they apply both to cores and the entire package — i.e. if all cores are idle then the entire package can also become idle, ...

How can we design for all types of users? - Learn web development
color contrast to keep your text readable, use a text color that contrasts well with the background color. make it extra easy to read the text, to help visually-impaired people and people using their phones on the street. the w3c defines a good color mix with an algorithm that calculates luminosity ratio between foreground and background. the calculation may seem pretty complicated, but we can rely on tools to do the job for us. let's download and install the paciello group's colour contrast analyser. note: alternatively you can find a number of contrast checkers online, such as webaim's color contrast checker. we suggest a local checker because it comes packaged with an on-screen color picker to find out a color value. for instance, let's test the colors on this page and see how we f...

An overview of HTTP - HTTP
ndividual messages (as opposed to a stream of data). the messages sent by the client, usually a web browser, are called requests and the messages sent by the server as an answer are called responses. designed in the early 1990s, http is an extensible protocol which has evolved over time. it is an application layer protocol that is sent over tcp, or over a tls-encrypted tcp connection, though any reliable transport protocol could theoretically be used. due to its extensibility, it is used to not only fetch hypertext documents, but also images and videos or to post content to servers, like with html form results. http can also be used to fetch parts of documents to update web pages on demand. components of http-based systems http is a client-server protocol: requests are sent by one entity, ...

XPCOM array guide
he array. for most concrete c++ classes like nstarray<t> and nscomarray<t>, indexing should be faster than the callback-style enumeration, because accessing an indexed member of such an array is usually very fast, while enumeration has slight function call overhead. in the case of scriptable arrays like nsiarray however, the enumeration mechanism is often preferred because it avoids the addref / release overhead that comes from accessing each object. the only functional drawback to in-place enumeration is that you cannot manipulate the array itself during the enumeration. for example, you should not delete elements of an array during the enumeration as this will often confuse the loop which is enumerating the array. enumerators most arrays provide access to an object which is used to enum...

Screen Wake Lock API - Web APIs
creen awake). you acquire a wakelocksentinel object by calling the navigator.wakelock.request() promise based method that resolves if the platform allows it. a request may be rejected for a number of reasons, including system settings (such as power save mode or low battery level) or if the document is not active or visible. the sentinel is attached to the underlying system wake lock. it can be released by the system, again if the battery power is too low or the document is not active or visible. it can also be released manually via the wakelocksentinel.release() method. it is good practice to store a reference to the sentinel object to control release later and also to reacquire the lock if need be. the screen wake lock api should be used to keep the screen on to benefit usability. it's a...

Using Touch Events - Web APIs
the touch interface represents a single contact point on a touch-sensitive device. the contact point is typically referred to as a touch point or just a touch. a touch is usually generated by a finger or stylus on a touchscreen, pen or trackpad. a touch point's properties include a unique identifier, the touch point's target element as well as the x and y coordinates of the touch point's position relative to the viewport, page, and screen. the touchlist interface represents a list of contact points with a touch surface, one touch point per contact. thus, if the user activated the touch surface with one finger, the list would contain one item, and if the user touched the surface with three fingers, the list length would be three. the touchevent interface represents an event sent when the sta...

Web Authentication API - Web APIs
, enabling passwordless authentication and/or secure second-factor authentication without sms texts. web authentication concepts and usage the web authentication api (also referred to as webauthn) uses asymmetric (public-key) cryptography instead of passwords or sms texts for registering, authenticating, and second-factor authentication with websites. this resolves significant security problems related to phishing, data breaches, and attacks against sms texts or other second-factor authentication methods while at the same time significantly increasing ease of use (since users don't have to manage dozens of increasingly complicated passwords). many websites already have pages that allow users to register new accounts or sign in to an existing account, and the web authentication api acts as ...
