<div>{{CSSRef}}</div>
<p>A função CSS <code><strong>matrix()</strong></code> define uma matriz de transformação 2D homogênea. Isso resulta em um dado do tipo {{cssxref("<transform-function>")}} .</p>
<div class="note">
<p><strong>Note:</strong> <code>matrix(a, b, c, d, tx, ty)</code> is a shorthand for <code><a href="/en-US/docs/Web/CSS/transform-function/matrix3d">matrix3d</a>(a, b, 0, 0, c, d, 0, 0, 0, 0, 1, 0, tx, ty, 0, 1)</code>.</p>
</div>
<h2 id="Syntax">Syntax</h2>
<p>The <code>matrix()</code> function is specified with six values. The constant values are implied and not passed as parameters; the other parameters are described in the column-major order.</p>
<div class="note"><strong>Note:</strong> Until Firefox 16, Gecko accepted a {{cssxref("<length>")}} value for <var>tx</var> and <var>ty</var>.</div>
