Values

none
The element offers no user-controllable method for resizing the element.
both
The element displays a mechanism for allowing the user to resize the element, which may be resized both horizontally and vertically.
horizontal
The element displays a mechanism for allowing the user to resize the element, which may only be resized horizontally.
vertical
The element displays a mechanism for allowing the user to resize the element, which may only be resized vertically.
block
Depending on the writing-mode and direction value, the element displays a mechanism for allowing the user to resize the element either horizontally or vertically in block direction.
inline
Depending on the writing-mode and direction value, the element displays a mechanism for allowing the user to resize the element either horizontally or vertically in inline direction.
Note: resize does not apply to blocks for which the overflow property is set to visible.

Formal syntax

none | both | horizontal | vertical

Examples

Disabling resizability of textareas

CSS

By default, <textarea> elements are resizable in Gecko 2.0 (Firefox 4). You may override this behavior with the CSS shown below:

textarea.example {
  resize: none; /* disables resizability */
}

HTML

<textarea class="example">Type some text here.</textarea>

Result

Using resize with arbitrary elements

You can use the resize property to make any element resizable. In the example below, a resizable <div> box contains a resizable paragraph (<p> element):

CSS

.resizable {
  resize: both;
  overflow: scroll;
  border: 1px solid black;
}

div {
  height: 300px;
  width: 300px;
}

p {
  height: 200px;
  width: 200px;
}

HTML

<div class="resizable">
  <p class="resizable">
    This paragraph is resizable, because the CSS resize property is set to 'both' on this
    element.
  </p>
</div>

Result
