How do I disable the resizable property of a textarea in CSS?

To disable the resizable property of a <textarea>, use the following CSS:

textarea {
  resize: none;    /* disables manual resizing */
  overflow: auto;  /* or 'hidden' if you don't want scrollbars */
}

• resize: none; prevents the user from manually dragging to resize the textarea.
• Optionally, set overflow to control whether scrollbars appear when the content is larger than the visible area.

This is well-supported in modern browsers; however, for completeness, older browsers might need vendor prefixes (e.g., -webkit-resize: none;) if you’re targeting very old versions.
