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

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

Any content between the <canvas><\/code><\/canvas><\/code> tags is “fallback content”- meaning, it will be displayed only if the canvas cannot be displayed.<\/p>\n
