Web developers are concerned about the coexistence of IE7 and IE8 in fact can be very good solution.
Solution One:
In the upper right corner of the browser there is a "mimic IE7" toggle button, but a bit troublesome, you need to close the browser and then reopen it.
Solution Two:
In the developer tools IE8 comes with, click View Select Striet (Internet Explorer7) to see the effects under IE7 without restarting the browser.
can only provide IE5/7/8 three kinds, and no IE6 mode, fortunately I have "href=" Http://tredosoft.com/Multiple_IE "target=" _blank ">multiple-ie".
Solution Three: because IE8 contains IE7 kernel, so casually install a browser with IE kernel, such as the window of the world and Proud tour, open a Web page to see, he is the default use of the system inside the IE7 core, haha
By the way, IE8 's development tools have a good feature, or they may not have been noticed in the previous development tools.
