Textarea Sizing: CSS vs. HTML Attributes: Which One to Choose?

How to Size a Textarea: CSS vs. HTML Attributes

When developing forms with textareas, the question arises: should we use CSS properties or HTML attributes (cols and rows) to define their dimensions? Each method has its advantages and disadvantages, which we'll explore here.

CSS Properties: width and height

Pros:

• Precise control over the textarea's size in pixels.
• Convenient for responsive layouts where the textarea needs to adapt dynamically.
• Easier to style the textarea consistently across different browsers.

Cons:

• May not be supported in older browsers that don't support CSS.
• Can override the user's browser preferences for textarea size.

HTML Attributes: cols and rows

Pros:

• Required for accessibility and usability, ensuring the textarea is visible in text-only browsers.
• Controls the number of columns and rows, providing a consistent visual appearance.
• Can be used to specify a minimum textarea size, giving users more flexibility.

Cons:

• Less precise control over the exact size, as it depends on the font and CSS styles.
• Not as convenient for responsive layouts.
• May not be as visually consistent as using CSS.

Recommended Approach

The best practice is to use both CSS and HTML attributes for the most comprehensive sizing solution.

<code class="css">textarea {
  width: 300px;
  height: 150px;
}</code>

<code class="html"><textarea cols="30" rows="10"></textarea></code>

This approach ensures compatibility with older browsers while giving you precise control over the textarea's size and appearance.
