问题 I am trying to make my website accessible in high-contrast mode. In order to detect when high-contrast mode is enabled, I created a JavaScript method to detect if background images are disabled, because high-contrast mode disables background images. Then if the browser is in high-contrast mode, I append a CSS file to make fixes for displaying in high contrast.

问题 I have a .NET Winform with a background image, and testing just reported the BackgroundImage is hidden when display settings in Win7 are set to high contrast mode. I understand why MS does this by default, but I'm hoping there is a way to override this behavior without changing the layout of my form?

问题 When pressing Shift + Left + Alt + Print Windows switches into high contrast mode - is there any chance to detect that on a web page (using JavaScript or CSS)? Is there any chance to detect that in the HTTP-Request (a.k.a the server-side e.g. via PHP or Ruby)? 回答1: According to this article about using CSS sprites in high contrast, in high contrast mode on Windows, background images should be set to "none" and it also changes the background color. This should override any CSS stylesheet. So
