Create Headings – The <hn> Elements:

Any documents starts with a heading. You use different sizes for your headings. HTML also have six levels of headings, which use the elements <h1>, <h2>,<h3>,<h4>,<h5> and <h6>.

Example:

<h1>This is  heading 1</h1>

<h2>This is  heading 2</h2>

<h3>This is  heading 3</h3>

<h4>This is  heading 4</h4>

<h5>This is  heading 5</h5>

<h6>This is  heading 6</h6>

Create Paragraph – The <p> Element:

The <p> element offer a way to structure your text. Each paragraph of text should go in between an opening <p> and closing </p> tag.

Example:

<p>Here is  a paragraph of text.</p>

<p>Here is  a second paragraph of text.</p>

<p>Here is  a third paragraph of text.</p>

This will produce following result:

Here is  a paragraph of text.

Here is  a second paragraph of text.

Here is  a third paragraph of text.

You can use align attribute to align your paragraphs.

<p align=”left”>This is left aligned.</p>

<p align=”center”>This is center aligned.</p>

<p align=”right”>This is right aligned.</p>

<p align=”justify”>This is justify. This works when you have multiple lines in your paragraph and  you want to justify all the lines so that they can look more nice.</p>

Create Line Breaks – The <br /> Element:

Whenever you use the <br /> element, anything following it starts on the next line. This tag is an example of an empty element, where you do not need opening and closing tags, as there is nothing to go in between them.

Note: The <br /> element has a space between the characters br and the forward slash. If you omit this space, older browsers will have trouble rendering the line break, while if you miss the forward slash character and just use <br> it is not valid XHTML

Example:

Hello<br />

You come most carefully upon your hour.<br />

Thanks<br />

Nonbreaking Spaces:

Suppose you were to use the phrase “12 Angry Men.” Here you would not want a browser to split the “12” and “Angry” across two lines:

A  good example of this technique appears in the movie “12 Angry Men.”

In cases where you do not want the client browser to break text, you should use a nonbreaking space entity (&nbsp) instead of a normal space. For example, when coding the “12 Angry Men” paragraph, you would use something similar to the following code:

<p>A good example of this technique appears in the movie”12&nbsp;Angry&nbp;Men.”</p>

Preserve Formatting - The <pre> Element:

Sometimes we want our text to follow the exact format of how it is written in the HTML document. In those cases, we can use the preformatted tag(<pre>).

Any text between the opening <pre> tag and the closing </pre> tag will preserve the formatting of the source document.

<pre>

Function testFunction ( strText){

                Alert (strText)

}

</pre>

This will produce following result:

Function testFunction (strText){

                Alert (strTest)

}

Horizontal Rules – The <hr />Element:

Horizontal rules are used to visually break up sections of a document. The <hr> tag creates a line from the current position in the document to the right margin and breaks the line accordingly.

For example:   you may want to give a line between  two paragraphs as follows:

<p> This is paragraph one and should be on top </p>

<hr />

<p> This is paragraph two and should be on bottom </p>
