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
