The percentage of market share in the global desktop browser of Internet Explorer(IE) is less than 3%. If we are developing a site that includes global users or a sizable number of visitors from an older IE version then we have to make our website compatible with IE, even though that is outdated. The solution to this problem is X-UA-Compatible mode.
This article will tell you how to set IE(Internet Explorer) using HTML meta tags.
X-UA-Compatible is a document mode meta tag that allows us to choose which version of Internet Explorer the page should be rendered. Information about the http-equiv and content tags can be found at.
Example: This example uses a meta element that includes an X-UA-Compatible header and value of IE=9 in content attribute which limits the webpage features so that the webpage is supported by Windows Internet Explorer 9.
<!DOCTYPE html> <html>
<head>
<title>Your Webpage Title</title>
<!-- Use Internet Explorer 9 Standards mode -->
<meta http-equiv="X-UA-Compatible" content="IE=9">
</head>
<body>
<h>Your Heading</h>
<p>Your content goes here.</p>
</body>
</html>
|
The content of the http-equiv tags are below:
- IE=5: This mode renders the webpage as if it were displayed in Quirks mode by Internet Explorer 7.
- IE=7: This mode renders content as if it were displayed by Internet Explorer 7
- IE=8: This mode provides supports for many established standards in the industry.
-
IE=9: This mode provides the highest support for many established industry standards.
IE 9 does not support CSS3 animations. - IE=10: This mode provides the highest support for many established industry standards, like HTML5, CSS3.
- IE=11: This mode provides the highest support for established and emerging industry standards, like HTML5, CSS3.
- IE=edge: This mode instructs Internet Explorer to display content in the highest mode available.
- IE=EmulateIE7: Works same as IE=7 mode if a valid <!DOCTYPE> declaration is present otherwise in Quirks Mode.
- IE=EmulateIE8: Works same as IE=8 mode if a valid <!DOCTYPE> declaration is present otherwise in Quirks Mode.
- IE=EmulateIE9: Works same as IE=9 mode if a valid <!DOCTYPE> declaration is present otherwise in Quirks Mode.
- IE=EmulateIE10: Works same as IE=10 mode if a valid <!DOCTYPE> declaration is present otherwise in Quirks Mode.
- IE=EmulateIE11: Works same as IE=11 mode if a valid <!DOCTYPE> declaration is present otherwise in Quirks Mode.
Quirks Mode: This mode is a technique used by some browsers in maintaining backward compatibility for pages developed for older browsers, like in our case Internet Explorer.
