Starting with Internet Explorer 8, a compatibility view feature was shipped by Microsoft in Internet Explorer to help users deal with web page rendering issues. It was implemented as a button on the address bar. Sometimes websites don’t look like you expect them to–images might not appear, menus might be out of place, and text could be jumbled together. This might be caused by a compatibility problem between Internet Explorer and the site you’re on. Sometimes this can be fixed by adding the site to your Compatibility View list.
Internet Explorer 11 no longer has the familiar Compatibility View button next to the URL. This is how you can still use Compatibility View without the button.
To add a site to the compatibility view list
open the Internet Explorer and click the Tools button which lies on top right corner of Internet Explorer 11
select or click Compatibility View Setting
Under Add this website, enter the URL of the site you want to add to the list, and then tap or click Add.
After adding to compatibility view Internet Explorer 11 will automatically show that site in compatibility view and if it looks like worse again then the problem might not be compatibility and you can turn it off by removing it from your compatibility list
