<p class="summary">Ditambahkan di <a href="/en-US/docs/HTML/HTML5">HTML5</a>, <strong>elemen HTML {{HTMLElement("canvas")}} </strong>dapat digunakan untuk menggambar grafik melalui skrip di <a href="/en-US/docs/Web/JavaScript">JavaScript</a>. Sebagai contoh, dapat digunakan untuk menggambar graf, membuat komposisi foto, mencipta animasi, atau bahkan melakukan pemrosesan atau rendering video secara waktu-nyata .</p>
<p>Aplikasi Mozilla mendapat dukungan untuk <code><canvas></code> sejak Gecko 1.8 (i.e. <a href="/en-US/docs/Mozilla/Firefox/Releases/1.5">Firefox 1.5</a>). Elemen tersebut semula dikenalkan oleh Apple untuk Dashboard OS X dan Safari. Internet Explorer mendukung <code><canvas></code> sejak versi 9 dan seterusnya; untuk versi awal IE, sebuah halaman dapat secara efektif mendukung <code><canvas></code> dengan memasukkan skrip dari proyek <a href="https://github.com/arv/explorercanvas">Explorer Canvas</a> Google. Google Chrome dan Opera 9 juga mendukung <code><canvas></code>.</p>
<p>Elemen <code><canvas></code> juga digunakan oleh <a href="/en-US/docs/Web/WebGL">WebGL</a> untuk menggambar grafik hardware-accelerated 3D di halaman web.</p>
