+
+<p>O elemento HTML <em>Canvas</em> (<code>&lt;canvas&gt;</code>) pode ser utilizado para desenhar gráficos utilizando scripts (geralmente <a href="/en/JavaScript" title="en/JavaScript">JavaScript</a>). Por exemplo, além de desenhar gráficos, ele pode ser usado para fazer composições de fotos e também para animações. Você poderá colocar conteúdos alternativos dentro do bloco <code>&lt;canvas&gt;</code>. Este conteúdo será renderizado também em navegadores antigos e em navegadores com JavaScript desabilitado.</p>
