How to Automatically Adjust Text Area Height to Fit Content?

Height Adjustment for Text Areas

Many developers encounter the challenge of making textarea elements automatically adjust their height to accommodate the content they contain. This enhances user experience by removing unnecessary scroll bars.

To address this need, a JavaScript-based solution is available:

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

Along with this JavaScript code, CSS styles can be implemented to handle the aesthetics of the textarea:

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

HTML implementation utilizes the oninput event to trigger the height adjustment:

<textarea oninput="auto_grow(this)"></textarea>

With this approach, textareas will automatically expand or contract their height based on the amount of text entered, removing the need for scroll bars and ensuring a seamless user experience.
