Textarea resize control is available via the CSS3 resize property:
textarea { resize: both; } /* none|horizontal|vertical|both */
textarea.resize-vertical{ resize: vertical; }
textarea.resize-none { resize: none; }
Allowable values self-explanatory: none
(disables textarea resizing), both
, vertical
and horizontal
.
Notice that in Chrome, Firefox and Safari the default is both
.
If you want to constrain the width and height of the textarea element, that's not a problem: these browsers also respect max-height
, max-width
, min-height
, and min-width
CSS properties to provide resizing within certain proportions.
Code example:
#textarea-wrapper {_x000D_
padding: 10px;_x000D_
background-color: #f4f4f4;_x000D_
width: 300px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea {_x000D_
min-height:50px;_x000D_
max-height:120px;_x000D_
width: 290px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea.vertical { _x000D_
resize: vertical;_x000D_
}
_x000D_
<div id="textarea-wrapper">_x000D_
<label for="resize-default">Textarea (default):</label>_x000D_
<textarea name="resize-default" id="resize-default"></textarea>_x000D_
_x000D_
<label for="resize-vertical">Textarea (vertical):</label>_x000D_
<textarea name="resize-vertical" id="resize-vertical" class="vertical">Notice this allows only vertical resize!</textarea>_x000D_
</div>
