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!!

Solution

  • 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 (deleted post, web archive link)

    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>
