High Contrast themes on Windows 7 overwrites css styles in firefox and IE!

How can I continue to use the high-contrast styles in Windows 7 and not have it interfere with Firefox (3.6.3) and IE 8 (64-bit and 32-bit) browsers. Chrome displays the web pages as the web designers coded them.

Any and all colors and images defined in the css (style sheets, page level and embedded styles) are removed or replaced with the high-contrast theme settings. Images embedded on the web pages display (but most of my front-end work consists of css background images).

I am a web developer who codes in a dark cave-like office. I don't want the too-bright aero theme and I do not want, nor need, Micro$oft to dictate how my applications should work (and render CSS!) based on display settings nor how I should do my work (i.e., in a bright environment).

What is the solution besides losing the Windows look and feel that a) is power saving (the monitors consume less energy displaying dark backgrounds over white) and b) easier on my eyes. 

Thank you,




Hi Drew,


High Contrast themes are basically intended to increase legibilityby heightening screen contrast with alternative color combinations. To a certain extend this can help in saving power and at the same time improve the performance of the computer. Aero themes consume more memory as compared to the basic or high contrast themes. This can slow down the computer performance if the theme consumes more than the allowed memory. In such case, you can choose the basic theme or the high-contrast theme to improve its performance.

Besides, you can download other themes available online that suits your requirement.

Coming to the CSS style problem with high contrast theme, MSDN forum would be the best place to put across the query.
