overflow-x
The overflow-x
CSS property sets what shows when content overflows a block-level element's left and right edges. This may be nothing, a scroll bar, or the overflow content. This property may also be set by using the overflow
shorthand property.

Syntax
css
/* Keyword values */
overflow-x: visible;
overflow-x: hidden;
overflow-x: clip;
overflow-x: scroll;
overflow-x: auto;
/* Global values */
overflow-x: inherit;
overflow-x: initial;
overflow-x: revert;
overflow-x: revert-layer;
overflow-x: unset;
The overflow-x
property is specified as a single <overflow>
keyword value.
If overflow-y
is hidden
, scroll
, or auto
, and the overflow-x
property is visible
(default), the value will be implicitly computed as auto
.
Values
visible
-
Overflow content is not clipped and may be visible outside the element's padding box on left and right edges. The element box is not a scroll container.
-
Overflow content is clipped if necessary to fit horizontally in the elements' padding box. No scroll bars are provided.
clip
-
Overflow content is clipped at the element's overflow clip edge that is defined using the
overflow-clip-margin
property. As a result, content overflows the element's padding box by the<length>
value ofoverflow-clip-margin
or by0px
if not set. The difference betweenclip
andhidden
is that theclip
keyword also forbids all scrolling, including programmatic scrolling. No new formatting context is created. To establish a formatting context, useoverflow: clip
along withdisplay: flow-root
. The element box is not a scroll container. scroll
-
Overflow content is clipped if necessary to fit horizontally inside the element's padding box. Browsers display scroll bars in the horizontal direction whether or not any content is actually clipped. (This prevents scroll bars from appearing or disappearing when the content changes.) Printers may still print overflowing content.
auto
-
Overflow content is clipped at the element's padding box, and overflow content can be scrolled into view. Unlike
scroll
, user agents display scroll bars only if the content is overflowing and hide scroll bars by default. If content fits inside the element's padding box, it looks the same as withvisible
, but still establishes a new block-formatting context. Desktop browsers provide scroll bars if content overflows.Note: The keyword value
overlay
is a legacy value alias forauto
. Withoverlay
, the scroll bars are drawn on top of the content instead of taking up space.

Examples
HTML
html
<ul>
<li>
<code>overflow-x:hidden</code> — hides the text outside the box
<div id="div1">ABCDEFGHIJKLMOPQRSTUVWXYZABCDEFGHIJKLMOPQRSTUVWXYZ</div>
</li>
<li>
<code>overflow-x:scroll</code> — always adds a scrollbar
<div id="div2">ABCDEFGHIJKLMOPQRSTUVWXYZABCDEFGHIJKLMOPQRSTUVWXYZ</div>
</li>
<li>
<code>overflow-x:visible</code> — displays the text outside the box if
needed
<div id="div3">ABCDEFGHIJKLMOPQRSTUVWXYZABCDEFGHIJKLMOPQRSTUVWXYZ</div>
</li>
<li>
<code>overflow-x:auto</code> — on most browsers, equivalent to
<code>scroll</code>
<div id="div4">ABCDEFGHIJKLMOPQRSTUVWXYZABCDEFGHIJKLMOPQRSTUVWXYZ</div>
</li>
</ul>
