问题 @media only screen and (min-width: 480px) and (max-width: 767px) { } Here is my media query how to fix it. how to set for safari web browser. 回答1: Media queries aren't made for browser detection.

问题 My application displays a small banner loaded from the web in a TWebBrowser control. This banner is actually a HTML page including an image; when the users click the image it takes them to the promotional campaign we're currently running. The bad thing here is that when clicking the link in TWebBrowser, the campaign page is opened in Internet Explorer, not in their default browser. I know this happens because TWebBrowser is a IE-based control, but is there a way to open the link in users'
