HTML 5 <canvas> Tag

The HTML <canvas> tag is used for creating graphics on the fly. It can be used for rendering graphs, game graphics, or other visual images.

To draw on the canvas, the <canvas> tag is used in conjunction with the getContext(contextId) method.

Any content between the <canvas></canvas> tags is "fallback content"- meaning, it will be displayed only if the canvas cannot be displayed.

The <canvas> tag was introduced in HTML 5.

Attributes

HTML tags can contain one or more attributes. Attributes are added to a tag to provide the browser with more information about how the tag should appear or behave. Attributes consist of a name and a value separated by an equals (=) sign, with the value surrounded by double quotes. Here's an example, style="color:black;".

There are 3 kinds of attributes that you can add to your HTML tags: Element-specific, global, and event handler content attributes.

The attributes that you can add to this tag are listed below.

Element-Specific Attributes

The following table shows the attributes that are specific to this tag/element.

Global Attributes

The following attributes are standard across all HTML 5 tags.

For a full explanation of these attributes, see HTML 5 global attributes.

Event Handler Content Attributes

Event handler content attributes enable you to invoke a script from within your HTML. The script is invoked when a certain "event" occurs. Each event handler content attribute deals with a different event.

Here are the standard HTML 5 event handler content attributes.
