HTML canvas element

Use the HTML <canvas> element with either the canvas scripting API or the WebGL API to draw graphics and animations.

You should provide alternate content inside the <canvas> block. That content will be rendered both on older browsers that don’t support canvas and in browsers with JavaScript disabled.

Unlike the <img> element, the <canvas> element requires the closing tag (</canvas>).

The displayed size of the canvas can be changed using CSS, but if you do this the image is scaled during rendering to fit the styled size, which can make the final graphics rendering end up being distorted.

It is better to specify your canvas dimensions by setting the width and height attributes directly on the <canvas> elements, either directly in the HTML or by using JavaScript.
