I didn't know when to get bored yesterday. Today I found that all the web page backgrounds and styles of IE are gone. It was later remembered that the high contrast was enabled in the auxiliary function.
Symptoms:
1. Use IE (other browsers with IE as the core, such as roaming) to display Large fonts on webpages;
2. ie shows that the webpage has no background, no background image or background color, and any webpage has a white background.
3. Windows styles cannot be started. And so on.
Solution:
1. choose "start"> "Settings"> "Control Panel"> "auxiliary functions"> "display", and remove "√" before "use high contrast". "OK, re-open IE to solve the problem of "a large font is displayed on the webpage.
2. Open IE (other browsers also perform similar operations), tools-> Internet Options-> auxiliary functions-> remove all √-> OK, and solve the problem that IE displays no background.
