Hello, I got a question about styles in SMIL after staring at standard Courier 10 black on white font in the text elements. It would be nice to format text using CSS2. However, none of the SMIL elements have the style attribute. It would be nice to know why? I know there are alternative ways to do this, one is to use external stylesheets in the beginning of the XML document: <?xml-stylesheet href="style.css" type="text/css"?> However, I consider this limiting, especially for scripting. Frequently, the color of the text is wanted to be changed when mouse is over it. But, the above stylesheet can't be modified from the script and prevents changing the color. One solution is to use the <layout type="text/css"> element. The regions will then be defined using CSS2, which includes text formatting, for example: [region="b"] { top: 20px; left: 10px; font-family: Arial; color: blue; } [region="r"] { top: 20px; left: 10px; font-family: Arial; color: red; } The script would then change the region of the text element from 'b' to 'r'. <text region="b" ... > becomes <text region="r" ... > Another way is to use CSS2 classes: [region="area"] { top: 20px; left: 10px; } .red { color: red; } .blue { color: blue; } The script would then change the class attribute of the text element from 'red' to 'blue'. <text class="red" region="area" ... > becomes <text class="blue" region="area" ... > But I find this a bit cumbersome. The way it would be done in HTML is: <text region="area" style="color: red;"> and the style attribute would then be changed using the script. I understand this may produce some problems. The region of the media element could be defined using the style attribute: <text region="area" style="top: 10px; left: 20px"> and this is probably something unwanted. (or is it?) It would be nice to hear opinions about this. Is there a reason not to have the style attribute? SVG and XHTML have it. They also have a style element. - Kari
