CSS Textarea that expands as you type text [duplicate]

Answer 1

This cannot be done with CSS alone. try the autogrow jquery plugin. https://github.com/jaz303/jquery-grab-bag/blob/master/javascripts/jquery.autogrow-textarea.js

You can also see autogrow demo here http://onehackoranother.com/projects/jquery/jquery-grab-bag/autogrow-textarea.html

It's lightweight and easy to use. Here's how it's done. Define your textarea id. Include the jquery js file before . Then between script tags, issue the jquery command $("#txtInput").autoGrow();
