VisualizaçõesCSS 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!!

I know this is a little bit late, but I have to say there is a way to use <div> with contenteditable attribute to simulate desired behaviour.
.textareaElement {
width: 300px;
min-height: 17px;
border: 1px solid #ccc;
max-height: 150px;
overflow-x: hidden;
overflow-y: auto;
}<div class="textareaElement" contenteditable></div>Just set your min and max height, with proper overflow values, and you have fully functional pure CSS expanding textbox, that is also well supported.

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>

This jQuery plugin is a really great one: http://www.jacklmoore.com/autosize
I've tested a bunch of these and this is by far the nicest. Also gives an example of using a CSS transition effect which is pretty slick.
