+<p class="summary">Added in <a href="/en-US/docs/HTML/HTML5">HTML5</a>, the <strong>HTML {{HTMLElement("canvas")}} element</strong> can be used to draw graphics via scripting in <a href="/en-US/docs/Web/JavaScript">JavaScript</a>. For example, it can be used to draw graphs, make photo compositions, create animations, or even do real-time video processing or rendering.</p>
+
+<p>Mozilla applications gained support for <code>&lt;canvas&gt;</code> starting with Gecko 1.8 (i.e. <a href="/en-US/docs/Mozilla/Firefox/Releases/1.5">Firefox 1.5</a>). The element was originally introduced by Apple for the OS X Dashboard and Safari. Internet Explorer supports <code>&lt;canvas&gt;</code> from version 9 onwards; for earlier versions of IE, a page can effectively add support for <code>&lt;canvas&gt;</code> by including a script from Google's <a href="https://github.com/arv/explorercanvas">Explorer Canvas</a> project. Google Chrome and Opera 9 also support <code>&lt;canvas&gt;</code>.</p>
+
+<p>The <code>&lt;canvas&gt;</code> element is also used by <a href="/en-US/docs/Web/WebGL">WebGL</a> to draw hardware-accelerated 3D graphics on web pages.</p>

+<p><a href="/en-US/docs/Web/HTML/Element/canvas" title="HTML/Canvas"><strong><code>&lt;canvas&gt;</code></strong></a> is an <a href="/en-US/docs/Web/HTML" title="HTML">HTML</a> element which can be used to draw graphics via scripting (usually <a href="/en-US/docs/Glossary/JavaScript" title="JavaScript">JavaScript</a>). This can, for instance, be used to draw graphs, make photo composition or simple (and <a href="/en-US/docs/Web/API/Canvas_API/A_basic_ray-caster" title="A_Basic_RayCaster">not so simple</a>) animations. The images on this page show examples of <a href="/en-US/docs/Web/HTML/Element/canvas" title="HTML/Canvas"><strong><code>&lt;canvas&gt;</code></strong></a> implementations which will be created in this tutorial.</p>
+</div>
+
+<p><span class="seoSummary">This tutorial describes how to use the <code>&lt;canvas&gt;</code> 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.</span></p>
+
+<p>First introduced in WebKit by Apple for the OS X Dashboard, <code>&lt;canvas&gt;</code> has since been implemented in browsers. Today, all major browsers support it.</p>
+
+<h2 id="Before_you_start" name="Before_you_start">Antes de começar</h2>
+
+<p>Using the <code>&lt;canvas&gt;</code> element is not very difficult, but you do need a basic understanding of <a href="/en-US/docs/Web/HTML" title="HTML">HTML</a> and <a href="/en-US/docs/Web/JavaScript" title="JavaScript">JavaScript</a>. The <code>&lt;canvas&gt;</code> element is not supported in some older browsers, but is supported in recent versions of all major browsers. The default size of the canvas is 300 px × 150 px (width × height). But custom sizes can be defined using the HTML <code>height</code> and <code>width</code> property. In order to draw graphics on the canvas we use a JavaScript context object, which creates graphics on the fly.</p>
