When Internet Explorer detects a web page that is incompatible with the current version of the browser, in the address bar there is a button "compatibility View". To see it, you need to call up the main system menu by clicking "start" and go to "All programs." Start Internet Explorer and navigate to the desired web page. Determine the current state of compatibility mode is an active mode status is displayed as a colored button that is disabled - schematic. To disable the active state of the compatibility mode, simply press the colour button.
Expand the tools menu of the top toolbar of Internet Explorer and point to "Settings for compatibility view". Clear the check box in the row "Display all nodes in the compatibility view mode" in the dialog window and confirm saving the changes by pressing the OK button.
An alternative method of disabling the display pages in compatibility mode is the use of the meta element, which is the same server response header, X-UA-Compatible with value IE=edge
tag meta http-equiv="X-UA-Compatible" content="IE=edge" / tag.
Note that the value IE=edge enforces the last possible mode of operation of the browser, without regard to its current version. Thus, the representation of web pages in compatibility mode with previous versions will be disabled programmatically. In Internet Explorer 8 edge mode: displays pages only at the level of this version: in version 9 - the next level. It is recommended to limit using this mode the test web pages and other purposes not related to the production, because the results of incorrect display of pages is not fully understood.
