Case-insensitive CSS attribute selectors

Last updated on : 2022-04-10

Note:
Case-insensitive CSS attribute selectors shows a browser compatibility score of 85. This is a collective score out of 100 to represent browser support of a web technology. The higher this score is, the greater is the browser compatibility. The browser compatibility score is not a 100% reflection for every browser and the web technology support. However, it does give you an estimate on how much you should rely on a particular web technology in terms of browser compatibility.

Overview

In CSS, using an i after the]' allows for case-insensitive matching. For example, [b='xyz'] will match both <a b=‘xyz’> and <a b=xYZ>.
