| 435 | Canvas API | API, Canvas, JavaScript, Overview, Reference |

| 436 | A basic ray-caster | Advanced, Canvas, Example, Graphics, HTML, Web |
| 437 | Canvas tutorial | Canvas, Graphics, Guide, HTML, HTML5, Intermediate, Web |
This tutorial describes how to use the <canvas> element to draw 2D graphics, starting with the basics. The examples provided should give you some clear ideas what you can do with canvas, and will provide code snippets that may get you started in building your own content. |
||
| 438 | Advanced animations | Canvas, Graphics, Tutorial |
| We are going to use a ball for our animation studies, so let's first draw that ball onto the canvas. The following code will set us up. | ||
| 439 | Applying styles and colors | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
Up until now we have only seen methods of the drawing context. If we want to apply colors to a shape, there are two important properties we can use: fillStyle and strokeStyle. |
||
| 440 | Basic animations | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
| Probably the biggest limitation is, that once a shape gets drawn, it stays that way. If we need to move it we have to redraw it and everything that was drawn before it. It takes a lot of time to redraw complex frames and the performance depends highly on the speed of the computer it's running on. | ||
| 441 | Basic usage of canvas | Canvas, Graphics, HTML, Intermediate, Tutorial |
At first sight a <canvas> looks like the <img> element, with the only clear difference being that it doesn't have the src and alt attributes. Indeed, the <canvas> element has only two attributes, width and height. These are both optional and can also be set using DOM properties. When no width and height attributes are specified, the canvas will initially be 300 pixels wide and 150 pixels high. The element can be sized arbitrarily by CSS, but during rendering the image is scaled to fit its layout size: if the CSS sizing doesn't respect the ratio of the initial canvas, it will appear distorted. |
||
| 442 | Compositing and clipping | Canvas, Graphics, HTML, HTML5, Intermediate, Tutorial |
We can not only draw new shapes behind existing shapes but we can also use it to mask off certain areas, clear sections from the canvas (not limited to rectangles like the clearRect() method does) and more. |

| This sample program demonstrates a number of compositing operations. The output looks like this: | ||
| 444 | Drawing shapes with canvas | Canvas, Graphics, HTML, HTML Canvas, HTML5, Intermediate, Tutorial |
 Before we can start drawing, we need to talk about the canvas grid or coordinate space. Our HTML skeleton from the previous page had a canvas element 150 pixels wide and 150 pixels high. To the right, you see this canvas with the default grid overlayed. Normally 1 unit in the grid corresponds to 1 pixel on the canvas. The origin of this grid is positioned in the top left corner at coordinate (0,0). All elements are placed relative to this origin. So the position of the top left corner of the blue square becomes x pixels from the left and y pixels from the top, at coordinate (x,y). Later in this tutorial we'll see how we can translate the origin to a different position, rotate the grid and even scale it, but for now we'll stick to the default. |

| 447 | Hit regions and accessibility | Canvas, Graphics, Tutorial |
The content inside the <canvas> ... </canvas> tags can be used as a fallback for browsers which don't support canvas rendering. It's also very useful for assistive technology users (like screen readers) which can read and interpret the sub DOM in it. A good example at html5accessibility.com demonstrates how this can be done: |

| This article is an overview of some powerful, fundamental DOM level 1 methods and how to use them from JavaScript. You will learn how to create, access and control, and remove HTML elements dynamically. The DOM methods presented here are not specific to HTML; they also apply to XML. The demonstrations provided here will work fine in any modern browser, including all versions of Firefox and IE 5+. | ||
| 917 | Using the W3C DOM Level 1 Core | DOM, NeedsUpdate |

| 919 | Whitespace in the DOM | DOM, Intermediate, NeedsUpdate |
The presence of whitespace in the DOM can make manipulation of the content tree difficult in unforeseen ways. In Mozilla, all whitespace in the text content of the original document is represented in the DOM (this does not include whitespace within tags). (This is needed internally so that the editor can preserve formatting of documents and so that white-space: pre in CSS will work.) This means that: |

The Event interface represents an event which takes place in the DOM; some are user-generated (such as mouse or keyboard events), while others are generated by APIs (such as events that indicate an animation has finished running, a video has been paused, and so forth). While events are usually triggered by such "external" sources, they can also be triggered programmatically, such as by calling the HTMLElement.click() method of an element, or by defining the event, then sending it to a specified target using EventTarget.dispatchEvent(). There are many types of events, some of which use other interfaces based on the main Event interface. Event itself contains the properties and methods which are common to all events. |

The Event interface's preventDefault() method tells the user agent that if the event does not get explicitly handled, its default action should not be taken as it normally would be. The event continues to propagate as usual, unless one of its event listeners calls stopPropagation() or stopImmediatePropagation(), either of which terminates propagation at once. |

||
| 1114 | Cross-global fetch usage | Cross global, Fetch, edge case, relative URL |
This article explains an edge case that occurs with fetch (and potentially other APIs exhibiting the same kind of resource retrieval behavior). When a cross-origin fetch involving a relative URL is initiated from an <iframe>, the relative URL used to be resolved against the current global location, rather than the iframe's location. |
||
| 1115 | Fetch basic concepts | API, Fetch, Fetch API, XMLHttpRequest, concepts, guard, request |
At the heart of Fetch are the Interface abstractions of HTTP Requests, Responses, Headers, and Body payloads, along with a global fetch method for initiating asynchronous resource requests. Because the main components of HTTP are abstracted as JavaScript objects, it is easy for other APIs to make use of such functionality. |
||
| 1116 | Using Fetch | API, BODY, Experimental, Fetch, Guide, HTTP, Promise, Response, fetch POST & string body, request |

||
| 1126 | FetchEvent.resultingClientId | API, DOM, FetchEvent, Property, Reference, Service Workers, Worker, resultingClientId |
The resultingClientId read-only property of the FetchEvent interface is the id of the client that replaces the previous client during a page navigation. |

Using the File API, which was added to the DOM in HTML5, it's now possible for web content to ask the user to select local files and then read the contents of those files. This selection can be done by either using an HTML <input> element or by drag and drop. |
||
| 1142 | File and Directory Entries API | API, File System API, File and Directory Entries API, Files, Non-standard, Overview, Reference |
| The File and Directory Entries API simulates a local file system that web apps can navigate within and access files in. You can develop apps which read, write, and create files and/or directories in a virtual, sandboxed file system. | ||
| 1143 | File and Directory Entries API support in Firefox | API, Chrome, Compatibility, File System API, File and Directory Entries API, Files, Firefox, Guide, Offline, Web Compatibility, google, google chrome |
| The original File System API was created to let browsers implement support for accessing a sandboxed virtual file system on the user's storage device. Work to standardize the specification was abandoned back in 2012, but by that point, Google Chrome included its own implementation of the API. Over time, a number of popular sites and Web applications came to use it, often without providing any means of falling back to standard APIs or even checking to be sure the API is available before using it. Mozilla instead opted to implement other APIs which can be used to solve many of the same problems, such as IndexedDB; see the blog post Why no FileSystem API in Firefox? for more insights. | ||
