This is a global style I use on sites that have ok margins but have tiny fonts, colors that are hard to see. I am nearsighted and slightly color blind so colors that don't have good contrast are hard to see. It will also highlight URLs and sets the background to white. The same as my other global but this one doesn't set margins.

I modified it some what after running into a site that insisted in having black backgrounds images, color and light grey text. It now forces no background image and makes most of the elements black text with no background also.
