CSS Textarea that expands as you type text
I have a Textarea where users can input text. By default it has a height of 17px. However if users insert a large amount of text, I want the text area to expand accordingly. Is there a way to do this with CSS ? Thanks in advance!!

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 </body>. Then between script tags, issue the jquery command $("#txtInput").autoGrow();
<body>
<textarea id="txtInput"></textarea>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js" type="text/javascript"></script>
<script>
$("#txtInput").autogrow();
</script>
</body>
