Hi, the site navigation bard (on gray) look different from page to page. I want it to keep the same size no matter what page I visit. I attached the CSS and the html pages.

* This problem seems to happen in Internet Explorer.

body {

Using pixels to define sizes causes all kinds of trouble. Different screen resolutions display the pixel sizes in different ways.

Negative sizes are not defined. This throws browsers into quirks mode.

Don't put size styles (width, height) and nonzero surround styles (margin, border, padding) in the same style or in the same tag. Using them together causes browser incompatibilities.

Don't put units of measure on 0 values. This causes Firefox to throw out the entire style and enter quirks mode.
