What Does Angle Bracket Mean?
The angle bracket (< or >), which is also called an “inequality sign”

include tags or pieces of code. This ASCII set of characters is common in web
design and other types of coding projects.
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.
