CSS, or Cascading Style Sheets, are files, provided along with HTML, to style the webpage accordingly.
How to include CSS in your HTML document
There are three different ways that CSS can be added into an HTML document;
<link> tag
The <link> tag must be placed within the <head> of a document.
<html>
<head>
<link href="myfile.css" rel="stylesheet" type="text/css" media="screen" />
</head>
<body>
</body>
</html>
<style> tag
The <style> tag is used to make CSS declarations directly in the HTML file's <head> tag.
<html>
<head>
<style type="text/css">
div#example {
color: black;
height: 50px;
width: 50px;
}
</style>
</head>
<body>
</body>
</html>
style attribute
Most HTML elements can have a style attribute added to them, so CSS may be applied directly to specific elements.
<html>
<head>
</head>
<body>
<div style="color:black; height:50px; width:50px;">
</div>
</body>
</html>
