Internet Explorer within a span of 7 years of its debut captured a market share of 95%, but its share has since crumbled to 3.2%. At present, IE experiences loads of compatibility issues and to add to its troubles, even Microsoft has pulled back all its support from IE’s earlier versions and has shifted its focus to its new browser, Microsoft Edge.
But even in spite of the dropped market share and lack of support, IE still manages to hold considerable ground in the market and, trust me when I say this, even the experience of your tiny percentage of users coming from IE can make or break your brand, making it absolutely critical to test for compatibility issues. Although this is a time when cross-browser compatibility is a big thing, all the browsers still behave differently, even when it comes to how margins and paddings are treated, how fonts are rendered, or how default styles of elements are interpreted, etc. IE itself is loaded with such issues and here I’m going to talk about some of the most prominent ones.
