<h2 id="Sumário">Sumário</h2>

<p>Comments are used to add explanatory notes or prevent the browser from interpreting parts of the style sheet.</p>

<p>Comments can be placed where ever white space is allowed within a style sheet.</p>

<h2 id="Sintaxe">Sintaxe</h2>

<pre class="syntaxbox">/* Comment */</pre>

<h2 id="Exemplos">Exemplos</h2>

<pre class="brush:css">/* A single line comment */

/*
A comment
which stretches
over several
lines
*/
</pre>

<h2 id="Notas">Notas</h2>

<p>The <code>/* */</code> comment syntax is used for both single and multi line comments. There is no other way to specify comments in external style sheets. However, when using the <code>&lt;style&gt;</code> element, you may use <code>&lt;!-- --&gt;</code> to hide CSS from older browsers, although this is not recommended. As in most programming languages that use the <code>/* */</code> comment syntax, comments cannot be nested. In other words, the first instance of <code>*/</code> that follows an instance of <code>/*</code> closes the comment.</p>
