Basic Tags
<p></p>
The <p> and </p> tags denote a paragraph. A line break generally appears before and after a paragraph. Here is an example:
<p> This is a paragraph. Many sentences can be contained within an HTML paragraph.</p>
<h1></h1>…<h6></h6>
The HTML heading tags are used to create headings of various sizes and importance within a document. <h1> is the largest and most emphasized, while <h6> is the smallest, and least emphasized.
<h1>Heading 1</h1> <h2>Heading 2</h2> <h3>Heading 3</h3> <h4>Heading 4</h4> <h5>Heading 5</h5> <h6>Heading 6</h6>
A line break <br /> is used to move the content which comes after it to the next line. The /> in the <br /> tag is a requirement for XHTML to close all tags. There are a number of tags which have to close themselves because there is no content markup to go between the tags.
The <hr /> tag creates a line across the page known as a horizontal rule. This can be beneficial in separating sections of a web page.
