Fixed Width HTML and High-Contrast System-Themes
Why is the default Zen Cart theme fixed width instead of 100% of the browser window? This makes it difficult for users with large fonts as the text often pushes out of the boundary area and or much farther down the page than is necessary.
On a similar note, using high-contrast system themes is difficult because highlighted input boxes have a lightly colored background while the sys. theme also uses a light font color. If styling input boxes, or any background for that matter, please go all the way and style the foreground color or don't style them at all. Form input is best left to the browser and system preference anyway.
