If you need to differentiate styles between Internet Explorer and other browsers like Firefox, Chrome, etc., consider using Conditional Comments.
<!--[if lt IE 9]>
<link href="path-to-file/IE.css" rel="stylesheet" type="text/css" />
<![endif]-->
By using this method, you can instruct Internet Explorer to apply a different stylesheet compared to other browsers such as Firefox.
Dealing with Internet Explorer can be challenging, so experiment with your stylesheet until it functions as intended.
To further segment styles within your stylesheet, check out this useful resource: CSS browser selectors. This JavaScript plugin allows you to target specific browsers by using prefixes like .webkit or .ie in your stylesheets.
