Using the :target pseudo-class in selectors - CSS: Cascading Style Sheets
when a url points at a specific piece of a document, it can be difficult for the user to notice. find out how you can use some simple css to draw attention to the target of a url and improve the user's experience. picking a target the pseudo-class :target is used to style the target element of a url containing a fragment identifier. for example, the url http://developer.mozilla.org/en/docs/using_the_:target_selector#example contains the fragment identifier #example. in html, identifiers are found as the values of either id or name attributes, since the two share the same namespace. thus, the example url would point to the heading "example" in this document. suppose you wish to style any h2 element that is the target of a url, but do not want any other kind of element to get a target style. t...

Inputs and input sources - Web APIs
r provides support for a variety of kinds of input devices. in this guide, we'll look at how to use webxr's input device management features to determine what input sources are available and how to then monitor those sources for inputs in order to handle user interactivity with your virtual or augmented environment. inputs in webxr fundamentally, inputs in webxr fall into two basic categories: targeting and actions. targeting is the specification of a point in space by the user's input. this may involve the user simply tapping on a spot on the screen, tracking their eyes, or the use of a joystick or motion-sensing controller to move a cursor. actions include both selection actions, such as clicking on a button, and squeeze actions, such as pulling a trigger or tightening your grip while wear...

DevTools API - Firefox Developer Tools
a way to register and access developer tools in firefox. in terms of user interface, each registered tool lives in its own tab (we call one tab a panel). these tabs are located in a box we call a toolbox. a toolbox can be hosted within a browser tab (at the bottom or on the side), or in its own window (we say that the toolbox is undocked). a toolbox (and all the tools it contains) is linked to a target, which is the object the tools are debugging. a target is usually a web page (a tab), but can be other things (a chrome window, a remote tab,…). in terms of code, each tool has to provide a tooldefinition object. a definition is a js light object that exposes different information about the tool (like its name and its icon), and a build method that will be used later-on to start an instance of...

nt becomes hidden or visible, such as when the user switches tabs in their browser. the intersection observer api doesn't take this into account when detecting intersection, since intersection isn't affected by page visibility. therefore, we need to pause our timers while the page is tabbed out; hence this event listener. next we set up the options for the intersectionobserver which will monitor target elements (ads, in our case) for intersection changes relative to the document. the options are configured to watch for intersections with the document's viewport (by setting root to null). we have no margins to extend or contract the intersection root's rectangle; we want to match the boundaries of the document's viewport exactly for intersection purposes. and the threshold is set to an array con...
...options are configured to watch for intersections with the document's viewport (by setting root to null). we have no margins to extend or contract the intersection root's rectangle; we want to match the boundaries of the document's viewport exactly for intersection purposes. and the threshold is set to an array containing the values 0.0 and 0.75; this will cause our callback to execute whenever a targeted element becomes completely obscured or first starts to become unobscured (intersection ratio 0.0) or passes through 75% visible in either direction (intersection ratio 0.75). the observer, adobserver, is created by calling intersectionobserver's constructor, passing in the callback function, intersectioncallback, and our options. we then call a function buildcontents(), which we'll define lat...
...ll, or you might do it differently or using a different time interval. handling document visibility changes let's take a look at the handler for the visibilitychange event. our script receives this event when the document itself becomes visible or invisible. the most important scenario here is when the user switches tabs. since intersection observer only cares about the intersection between the targeted elements and the intersection root, and not the tab's visibility (which is a different issue entirely), we need to use the page visibility api to detect these tab switches and disable our timers for the duration. function handlevisibilitychange() { if (document.hidden) { if (!previouslyvisibleads) { previouslyvisibleads = visibleads; visibleads = []; previouslyvisiblead...

Introduction to cross browser testing - Learn web development
ws for cross browser testing all of this cross browser testing business may sound time consuming and scary, but it needn't be — you just need to plan carefully for it, and make sure you do enough testing in the right places to make sure you don't run into unexpected problems. if you are working on a large project, you should be testing it regularly, to make sure that new features work for your target audience, and that new additions to the code don't break old features that were previously working. if you leave all the testing to the end of a project, any bugs you uncover will be a lot more expensive and time consuming to fix than if you uncover them and fix them as you go along. the workflow for testing and bug fixes on a project can be broken down into roughly the following four phases (t...

... options optional an optional object which customizes the observer. if options isn't specified, the observer uses the document's viewport as the root, with no margin, and a 0% threshold (meaning that even a one-pixel change is enough to trigger a callback). you can provide any combination of the following options: root an element or document object which is an ancestor of the intended target, whose bounding rectangle will be considered the viewport. any part of the target not visible in the visible area of the root is not considered visible. rootmargin a string which specifies a set of offsets to add to the root's bounding_box when calculating intersections, effectively shrinking or growing the root for calculation purposes. the syntax is approximately the same as that for the cs...
...the syntax is approximately the same as that for the css margin property; see the root element and root margin in intersection observer api for more information on how the margin works and the syntax. the default is "0px 0px 0px 0px". threshold either a single number or an array of numbers between 0.0 and 1.0, specifying a ratio of intersection area to total bounding box area for the observed target. ...

Square tilemaps implementation: Scrolling maps - Game development

Recommended Drag Types - Web APIs
, use the text/plain type. the second data parameter should be the dragged string. for example: event.datatransfer.setdata("text/plain", "this is text to drag"); dragging text in textboxes and selections on web pages is done automatically by the browser, so you do not need to handle it yourself. it is recommended to always add data of the text/plain type as a fallback for applications or drop targets that do not support other types, unless there is no logical text alternative. always add this text/plain type last, as it is the least specific and shouldn’t be preferred. note: in older code, you may find text/unicode or the text types. these are equivalent to text/plain, and will store and retrieve plain text data. dragging links dragged hyperlinks should include data of two types: text/u...

WebAssembly Concepts - WebAssembly
oncepts behind how webassembly works including its goals, the problems it solves, and how it runs inside the web browser's rendering engine. what is webassembly? webassembly is a new type of code that can be run in modern web browsers and provides new features and major gains in performance. it is not primarily intended to be written by hand, rather it is designed to be an effective compilation target for low-level source languages like c, c++, rust, etc. this has huge implications for the web platform — it provides a way to run code written in multiple languages on the web at near-native speed, with client apps running on the web that previously couldn’t have done so. what’s more, you don’t even have to know how to create webassembly code to take advantage of it. webassembly modules...

(note that webassembly has the high-level goal of supporting languages with garbage-collected memory models in the future.) with the advent of webassembly appearing in browsers, the virtual machine that we talked about earlier will now load and run two types of code — javascript and webassembly. the different code types can call each other as required — the...

Type, class, and ID selectors - Learn web development
the same thing, the readability is significantly improved. class selectors the class selector starts with a full stop (.) character and will select everything in the document with that class applied to it. in the live example below we have created a class called .highlight, and have applied it to several places in my document. all of the elements that have the class applied are highlighted. targeting classes on particular elements you can create a selector that will target specific elements with the class applied. in this next example we will highlight a <span> with a class of highlight differently to an <h1> heading with a class of highlight. we do this by using the type selector for the element i want to target, with the class appended using a dot, with no white space in between. thi...
...eading with a class of highlight. we do this by using the type selector for the element i want to target, with the class appended using a dot, with no white space in between. this approach reduces the scope of a rule as the rule will only apply to that particular element & class combination; so you would need to add another selector if you decided the rule should apply to other elements too. target an element if it has more than one class applied you can apply multiple classes to an element and target them individually, or only select the element when all of the classes in the selector are present. this can be helpful when building up components that can be combined in different ways on your site. in the example below we have a <div> that contains a note. the grey border is applied when t...
...ebox as well to get anything applied. id selectors an id selector begins with a # rather than a full stop character, but is basically used in the same way as a class selector. an id however can be used only once per document, and elements can only have a single id value applied to them. it can select an element that has the id set on it, and you can precede the id with a type selector to only target the element if both the element and id match. you can see both of these uses in the following example: warning: using the same id multiple times in a document may appear to work for styling purposes, but don't do this. it results in invalid code, and will cause strange behavior in many places. note: as we learned in the lesson on specificity, an id has high specificity and will overrule mo...

IntersectionObserver - Web APIs
the intersectionobserver interface of the intersection observer api provides a way to asynchronously observe changes in the intersection of a target element with an ancestor element or with a top-level document's viewport. the ancestor element or viewport is referred to as the root. when an intersectionobserver is created, it's configured to watch for given ratios of visibility within the root. the configuration cannot be changed once the intersectionobserver is created, so a given observer object is only useful for watching for specific changes in degree of visibility; however, you can watch multiple target elements with the same observer. constructor intersectionobserver.intersectionobserver() creates a new intersectionobserver object which will execute a specified callback function whe...

...me as the one specified when calling the constructor as it may be changed to match internal requirements. each offset can be expressed in pixels (px) or as a percentage (%). the default is "0px 0px 0px 0px". intersectionobserver.thresholds read only a list of thresholds, sorted in increasing numeric order, where each threshold is a ratio of intersection area to bounding box area of an observed target. notifications for a target are generated when any of the thresholds are crossed for that target. if no value was passed to the constructor, 0 is used. methods intersectionobserver.disconnect() stops the intersectionobserver object from observing any target. intersectionobserver.observe() tells the intersectionobserver a target element to observe. intersectionobserver.takerecords() retu...

Digital audio concepts - Web media technologies
l minimize the compressed size of the audio while maximizing the percieved fidelity of the sound. an algorithm employing psychoacoustics may use any of the techniques mentioned here, and will almost certainly apply others as well. all of this means there is a fundamental question that has to be asked and answered before choosing a codec: given the content of the sound, the usage context, and the target audience, is it acceptable to lose some degree of audio fidelity, and if so, how much; or is it necessary that, upon decoding the data, the result be identical to the source audio? lossy vs lossless compression if loss of detail and potentially fidelity is unacceptable or undesirable, a lossless codec is preferred. on the other hand, if some degree of reduction of audio fidelity is okay, a loss...
...article, but it is useful to have a general idea of how audio gets compressed by common algorithms can help understand and make better decisions about audio codec selection. lossy compression algorithms generally use psychoacoustics to determine which components of an audio waveform can be lost or subdued in some way that can improve compression ratios while minimizing the audible effect for the target listeners. by manipulating the waveform to make it easier to compress, or by removing components of the sound that aren't really heard, the waveform becomes simpler, resulting in data which has more consistency and is therefore easier to compress. restricting the audio bandwidth to include only the frequencies most important to how the human ear will interpret the decoded sound can also improve c...
...a number of values you can adjust (some of which may require a deep understanding of both psychoacoustics and of the codec's algorithms), and others offer a simple "quality" parameter you can set, which automatically adjusts various properties of the algorithm. bit rate there are two mutually-exclusive ways to control the quality of the compressed audio using the bit rate. the first involves targeting an average bit rate for the encoded data, while the second involves specifying a constant quality value to target while allowing the bit rate to vary. average bit rate the first method for controlling the quality of the output file is to specify the average bit rate (abr) to target when encoding the audio. the encoder will attempt to produce an encoded sound file that, when playing it back, ...
...oding the audio. the encoder will attempt to produce an encoded sound file that, when playing it back, uses, on average, the specified number of bits for each second of audio. this controls quality from the perspective of the encoded audio size; the higher the bit rate, the higher the resulting audio quality will be. the quality of the audio will fluctuate over time as needed in order to meet the targeted bit rate. somewhat similar to abr is cbr (constant bit rate). where abr attempts to keep the bit rate on average at a given level, while allowing some fluctuation, cbr uses an actually fixed bit rate for the duration of the audio. cbr is primarily used in codecs designed for voice-only purposes, where the frequency range and variation tends to be minimal, allowing cbr encoding to work without ...

Performance fundamentals - Web Performance
an use to test and improve it. what is performance? ultimately, user-perceived performance is the only performance that matters. users provide inputs to the system through touch, movement, and speech. in return, they perceive outputs through sight, touch, and hearing. performance is the quality of system outputs in response to user inputs. all other things being equal, code optimized for some target besides user-perceived performance (hereafter upp) loses when competing against code optimized for upp. users prefer, say, a responsive, smooth app that only processes 1,000 database transactions per second, over a choppy, unresponsive app that processes 100,000,000 per second. of course, it's by no means pointless to optimize other metrics, but real upp targets come first. the next few subsecti...

... a guide as to how. framerate the first important thing for high framerate is to choose the right tool. use html and css to implement content that's mostly static, scrolled, and infrequently animated. use canvas to implement highly dynamic content, like games that need tight control over rendering and don't need theming. for content drawn using canvas, it's up to the developer to hit framerate targets: they have direct control over what's drawn. for html and css content, the path to high framerate is to use the right primitives. firefox is highly optimized to scroll arbitrary content; this is usually not a concern. but often trading some generality and quality for speed, such as using a static rendering instead of a css radial gradient, can push scrolling framerate over a target. css media q...
...s in css along with the rest of your app's look-and-feel, using a standardized syntax. css animations give you very granular control over your effects using keyframes, and you can even watch events fired during the animation process in order to handle other tasks that need to be performed at set points in the animation process. you can easily trigger these animations with the :hover, :focus, or :target, or by dynamically adding and removing classes on parent elements. if you want to create animations on the fly or modify them in javascript, james long has written a simple library for that called css-animations.js. use css transforms instead of tweaking absolute positioning and fiddling with all that math yourself, use the transform css property to adjust the position, scale, and so forth of ...

Progressive loading - Progressive web apps (PWAs)
about optimizing the image loading using javascript. we'll expain this below. placeholder image instead of having all the screenshots of games referenced in <img> element src attributes, which will force the browser to download them automatically, we can do it selectively via javascript. the js13kpwa app uses a placeholder image instead, which is small and lightweight, while the final paths to target images are stored in data-src attributes: <img src='data/img/placeholder.png' data-src='data/img/slug.jpg' alt='name'> those images will be loaded via javascript after the site finishes building the html structure. the placeholder image is scaled the same way the original images are, so it will take up the same space and not cause the layout to repaint as the images load. loading via javascri...

...ement to the previously working example — intersection observer will load target images only when the user scrolls down, causing them to display in the viewport. here's what the relevant code looks like: if('intersectionobserver' in window) { const observer = new intersectionobserver((items, observer) => { items.foreach((item) => { if(item.isintersecting) { loadimages(item.target); observer.unobserve(item.target); } }); }); imagestoload.foreach((img) => { observer.observe(img); }); } else { imagestoload.foreach((img) => { loadimages(img); }); } if the intersectionobserver object is supported, the app creates a new instance of it. the function passed as a parameter is handling the case when one or more items are intersecting with the ob...
...e more basic approach covered earlier. improvements remember that there are many ways to optimize loading times, and this example is exploring only one of the approaches. you could try to make your apps more bulletproof by making them work without javascript — either using <noscript> to show the image with final src already assigned, or by wrapping <img> tags with <a> elements pointing at the target images, so the user can click and access them when desired. we won't do that because the app itself is dependent on javascript — without it, the list of games wouldn't even be loaded, and the service worker code wouldn't be executed. we could rewrite the loading process to load not only the images, but the complete items consisting of full descriptions and links. it would work like an infinit...
