How do I disable the resizable property of a textarea?
I want to disable the resizable property of a textarea. Currently, I can resize a textarea by clicking on the bottom right corner and dragging the mouse. How can I disable this functionality?
To disable the resizable property of a textarea, use the CSS resize: none; property. This simple CSS rule will prevent users from resizing the textarea by clicking and dragging the bottom-right corner handle. The method works across modern browsers and can be implemented through external stylesheets, inline CSS, or JavaScript.

Using CSS to Disable Resizing
The primary and most straightforward method to disable textarea resizing is by using the CSS resize property with the value none. This property was introduced in CSS3 and specifically controls whether an element is resizable by the user.
External Stylesheet Method
Add the following CSS rule to your stylesheet:
textarea {
resize: none;
}
This will disable resizing for all textarea elements on your page.
Inline CSS Method
You can also apply the CSS directly to the textarea element:
<textarea style="resize: none;" rows="4" cols="50"></textarea>
Class-Based Method
For more selective control, you can create a CSS class:
.no-resize {
resize: none;
}
Then apply it to specific textareas:
<textarea class="no-resize" rows="4" cols="50"></textarea>
The Mozilla Developer Network explains that the resize property allows you to control whether an element is resizable by the user, with none being the value that completely disables this functionality.
Alternative Methods
While CSS is the recommended approach, there are alternative methods you can use if needed.
JavaScript Method
You can disable textarea resizing dynamically using JavaScript:
// Get all textareas
const textareas = document.querySelectorAll('textarea');
// Disable resizing for each textarea
textareas.forEach(textarea => {
textarea.style.resize = 'none';
});
This approach is useful when you need to control resizing based on user interactions or other dynamic conditions.
Limited Resizing Options
Instead of completely disabling resizing, you might want to limit it to one dimension:
/* Allow only vertical resizing */
textarea {
resize: vertical;
}
/* Allow only horizontal resizing */
textarea {
resize: horizontal;
}
According to davidwalsh.name, these values can help maintain certain design constraints while still allowing some user flexibility.
Browser Compatibility
The resize CSS property is supported by all modern browsers:
- Chrome: Full support since version 4
- Firefox: Full support since version 4
- Safari: Full support since version 3.1
- Edge: Full support since version 12
- Opera: Full support since version 15
However, there are some important considerations:
-
Overflow Property: The resize property has no effect unless the
overflowproperty is something other thanvisible(which is the default for most elements). For best results, combine it withoverflow: auto. -
Mobile Devices: On mobile devices, the resize functionality may not be available or may work differently due to touch interfaces.
Best Practices and Considerations
When disabling textarea resizing, consider these important factors:
User Experience
Disabling resizing can impact user experience, particularly for users who need larger text areas for accessibility or comfort. According to SourceBae, you should always weigh the design benefits against potential user needs before disabling resizing entirely.
Responsive Design
In responsive layouts, you might want to disable resizing on mobile devices while allowing it on desktop:
@media (max-width: 768px) {
textarea {
resize: none;
}
}
Combining with Other Properties
For better control, combine the resize property with other CSS properties:
textarea {
resize: none;
overflow: auto;
min-height: 50px;
max-width: 100%;
box-sizing: border-box;
}
This ensures the textarea behaves consistently across different screen sizes and content amounts.
Complete Example
Here’s a complete HTML example showing how to disable textarea resizing:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Textarea Resize Example</title>
<style>
/* External stylesheet method */
textarea {
resize: none;
overflow: auto;
min-height: 100px;
max-width: 100%;
padding: 10px;
border: 1px solid #ccc;
border-radius: 4px;
font-family: Arial, sans-serif;
}
/* Specific class for no-resize textareas */
.no-resize {
resize: none;
}
/* Limited resizing example */
.vertical-resize {
resize: vertical;
}
</style>
</head>
<body>
<h2>Textarea Resize Examples</h2>
<h3>Disabled Resizing (All textareas)</h3>
<textarea rows="4" cols="50">This textarea cannot be resized.</textarea>
<h3>Disabled Resizing (Specific class)</h3>
<textarea class="no-resize" rows="4" cols="50">This textarea also cannot be resized.</textarea>
<h3>Vertical Resizing Only</h3>
<textarea class="vertical-resize" rows="4" cols="50">This textarea can only be resized vertically.</textarea>
<script>
// JavaScript method to disable resizing
document.addEventListener('DOMContentLoaded', function() {
const textareas = document.querySelectorAll('textarea');
textareas.forEach(textarea => {
textarea.style.resize = 'none';
});
});
</script>
</body>
</html>
This example demonstrates multiple approaches to controlling textarea resizing, from CSS-based solutions to JavaScript manipulation.
