If you see your Internet Explorer showing that it’s using IE5 (Quirky) mode for a particular website, you might be wondering why?
As of the date this post has been written, IE11 is the latest version in most of the PCs (Edge is getting popular in Windows 10). So there are IE6, IE7, IE8, IE9, IE10, and IE11 available. Despite several better options, why is your website is rendered in IE5?
- “Via intranet compatibility settings” means that this checkbox is selected in compatibility view settings: “Display intranet sites in Compatibility View”
- This checkbox is selected probably by your IT department
- If this checkbox is selected and the page doesn’t have HTML5 document tag (
<!DOCTYPE html>), then the browser will render the page in IE5 (Quirks) mode
