<p><span class="seoSummary">The non-standard <strong><dfn><code>zoom</code></dfn></strong> <a href="/en-US/docs/Web/CSS">CSS</a> property can be used to control the magnification level of an element.</span> {{cssxref("transform-function/scale", "transform: scale()")}} should be used instead of this property, if possible. However, unlike CSS Transforms, <code>zoom</code> affects the layout size of the element.</p>

<pre class="brush: css no-line-numbers">/* Keyword values */
zoom: normal;
zoom: reset;

/* &lt;percentage&gt; values */
zoom: 50%;
zoom: 200%;

/* &lt;number&gt; values */
zoom: 1.1;
zoom: 0.7;

/* Global values */
zoom: inherit;
zoom: initial;
zoom: unset;</pre>
