Hi Recieved wisdom is that underscores in class names are not to be used, and I've just been asked if they are illegal or simply not recommended because of browser issues... and I haven't been able to find an absolute answer (probably looking in the wrong place). Does anyone have a definate answer to that? Rachel Andrew work: http://www.edgeofmyseat.com play: http://www.rachelandrew.co.uk WaSP Dreamweaver Task Force http://www.webstandards.org
