Can Automated Height Adjustment Eliminate Scrollbars in Textareas?

Auto-Adjusting Textarea Height

Q: Can I adjust the height of a textarea to match the height of the text it contains, eliminating the need for a scrollbar?

A: Yes, implementing this functionality is possible with JavaScript.

Here's a simple JavaScript code snippet that utilizes the scrollHeight property of the textarea element to automatically adjust its height as the user types:

function auto_grow(element) {
  element.style.height = "5px";
  element.style.height = (element.scrollHeight) + "px";
}

In addition, you can add CSS rules to prevent the textarea from resizing and hide the scrollbar:

textarea {
  resize: none;
  overflow: hidden;
  min-height: 50px;
  max-height: 100px;
}

With both the JavaScript function and CSS rules in place, the textarea will automatically adjust its height to accommodate the text content, providing a seamless user experience by eliminating the need for a scrollbar.
