Adjustable textarea with automatic height based on content and line breaks

Imagine you have a textarea with text that includes line breaks. If you style it like this:

textarea {
  height: auto;
  overflow: hidden;
  resize: none;
}

If you use the arrow keys to scroll down, you will find that the text is still present; it's just that the default height of the textarea is not enough to display all the text at once. To adjust this, you can utilize the rows attribute to specify how many rows should be visible by default in the textarea.

Alternatively, for more precise control, you can use a div with the attribute contenteditable="true".

textarea {
  height: auto;
  overflow: hidden;
  resize: none;
}

/*
* CSS for div with contenteditable="true"
*/
.textarea {
  display: inline-block;
  white-space: pre-wrap;
  overflow-wrap: break-word;
  border: 1px solid;
  padding: 2px;
}

<textarea rows="3">This is an

example text
</textarea>

<div class="textarea" contenteditable="true">This is an

example text
</div>

If you're looking for a quick fix, here is a simple solution I found. Using jQuery, you can adjust the height of a textarea to fit its content on document load:

$(document).ready(function() {
  var contentHeight = $('#your_textarea').prop('scrollHeight');
  $('#your_textarea').height(contentHeight);
});

It works perfectly!
