I'm not sure if it possible with textarea. Instead use div contentEditable.

You can't easily style the contents of a text area, you can however use a simplified rich text editor to accomplish this.
something like RTE: http://batiste.dosimple.ch/blog/posts/2007-09-11-1/rich-text-editor-jquery.html or CLEditor: http://premiumsoftware.net/cleditor/ would be a good starting point for this.
