<p class="desc"><strong>Description: </strong>An object containing all CSS properties that may be used without a unit. The <a href="/css/"><code>.css()</code></a> method uses this object to see if it may append <code>px</code> to unitless values.</p>

<p>You can think about <code>jQuery.cssNumber</code> as a list of all CSS properties you might use without a unit. It's used by <a href="/css/"><code>.css()</code></a> to determine if it needs to add <code>px</code> to unitless values.</p>
|
|
<p>The keys of the <code>jQuery.cssNumber</code> object are camel-cased and the values are all set to <code>true</code>. If you want to prevent the <a href="/css/"><code>.css()</code></a> method from automatically adding the <code>px</code> unit for a specific CSS property, you can add an extra property to the <code>jQuery.cssNumber</code> object.</p>
