What is HTML5 Syntax?

HTML5 elements can contain attributes that are used for setting different properties of the element. All attributes have a name and a value:


<!DOCTYPE html>

Meta Character Encoding

<meta charset = "UTF-8">

The <script> tag

<script src ="scriptfile.js"></script>

<link> tag

The<link>?tag defines the relationship between the document and external resources. I.e. in simple words, it is used to include the CSS files.

Use <link>? tag in <head>

<link rel ="stylesheet" href = "stylefile.css">
