Haven't updated outlineTextInput's for a while (due to having issues with IE) - which is a plugin for adding outlines to text fields when they are given focus. Done a new version which does seem to work: http://www.texotela.co.uk/code/jquery/focusfields/
Only done very basic testing on Firefox and Internet Explorer. The input's are given a transparent background in Opera, so that could be easily remedied by giving the inputs a background colour via CSS.
