translation_of: Web/CSS/overflow-block
---
<p>{{CSSRef}}</p>
<p>The <strong><code>overflow-block</code></strong> <a href="/en-US/docs/Web/CSS">CSS</a> property sets what shows when content overflows the block start and block end edges of a box. This may be nothing, a scroll bar, or the overflow content.</p>
<div class="note">
<p>The <code>overflow-block</code> property maps to {{Cssxref("overflow-y")}} or {{Cssxref("overflow-x")}} depending on the writing mode of the document.</p>
</div>
<h2 id="Syntax">Syntax</h2>
<pre class="brush:css no-line-numbers notranslate">/* Keyword values */
overflow-block: visible;
overflow-block: hidden;
overflow-block: scroll;
overflow-block: auto;
/* Global values */
overflow-block: inherit;
overflow-block: initial;
overflow-block: unset;
</pre>
<p>The <code>overflow-block</code> property is specified as a single keyword chosen from the list of values below.</p>
<h3 id="Values">Values</h3>
<dl>
<dt><code>visible</code></dt>
<dd>Content is not clipped and may be rendered outside the padding box's block start and block end edges.</dd>
<dt><code>hidden</code></dt>
<dd>Content is clipped if necessary to fit the block dimension in the padding box. No scrollbars are provided.</dd>
<dt><code>scroll</code></dt>
<dd>Content is clipped if necessary to fit in the block dimension in the padding box. Browsers display scrollbars whether or not any content is actually clipped. (This prevents scrollbars from appearing or disappearing when the content changes.) Printers may still print overflowing content.</dd>
<dt><code>auto</code></dt>
<dd>Depends on the user agent. If content fits inside the padding box, it looks the same as <code>visible</code>, but still establishes a new block-formatting context. Desktop browsers provide scrollbars if content overflows.</dd>
