Understanding HTML Tags

HTML tags are essential keywords that define how web browsers format and display content. They help distinguish HTML content from plain text. An HTML tag consists of three main parts: the opening tag, the content, and the closing tag. Some tags, known as self-closing tags, do not require a closing tag.

Basic Structure of an HTML Tag

<tag> content </tag>

Example Tags

<p> Hello Students this is a paragraph tag </p>
<h2> Hello Students this is heading </h2>
<b> Hello Students this text is bold. </b>
<i> Hello Students this text is italicized. </i>
