Techopedia explains Angle Bracket
One of the most common uses of angle brackets is in HTML code. As a major building block of web design, HTML is the primary structural part of most web source code. HTML is dependent on a large number of tags, many of which are included in angle brackets, to identify web elements and otherwise direct web browsers to render pages.
Angle brackets also have other uses. Visual Basic uses angle brackets to define attributes that add metadata to code.
