I had a problem with floats not working through my own stupidity (I used the class name "float"), and have discovered from a client that IE 5 Mac doesn't float the layers but places them in a list, the width of the container. >From http://www.w3.org/TR/CSS2/visuren.html#floats I see that "A floated box must have an explicit width", which is a shame as I wanted to use the code in a dynamic manner. In any case, I have posted my tests/results here: http://www.liamdelahunty.com/tips/css_class_float.php http://www.liamdelahunty.com/tips/css_class_float_min_width.php http://www.liamdelahunty.com/tips/css_class_float_width.php All work in windows IE 5.5 and Opera 7.01, so could some kind soul please have a look and let me know if any of the display works in IE Mac 5? (Any others too.) Kind regards, Liam
