A semantic UI open-source framework provides a segment or portion on a webpage that is used to create a group of related content. It is very similar to bootstrap usage and has different elements to make your website more amazing using jQuery and CSS for interfaces. For styling of elements, it uses classes.
Example:
html
<!DOCTYPE html>
<html>
<head>
<title>Semantic UI</title>
<link href=
"https://cdnjs.cloudflare.com/ajax/libs/semantic-ui/2.4.1/semantic.min.css"
rel="stylesheet" />
</head>
<body>
<div style="margin-top: 100px"
