Yes, I know. But my comics look horrible at width=100% on the desktop, but need to be width=100% for mobile in order to have it be at all legible. The ideal for me is if at screensize > 600px, width=600px. At screensize<600px, width=100%. That's possible with the CSS media property, but that has to be in the header style and not an in-line style. But the AO3 workskins don't allow the media property because they were designed before the media property existed.
