<h1> Header Tags

A header tag can be used to specify important information such as a page or paragraph title. It is written as <h1></h1> . The number in the tag specifies the size of text and can range from 1 to 6.

<h1>This is size 1</h1>

<h2>This is size 2</h2>

<h3>This is size 3</h3>

<h4>This is size 4</h4>

<h5>This is size 5</h5>

<h6>This is size 6</h6>

Header tags are important as they are often deemed to be significant by search engines when selecting sites in response to a query.

<hr> Horizontal Rule

A web page can be divided into sections by using the horizontal rule tag <hr>. It produces a default line like:

Parameters can be added to change the appearance of the line:

Width
width="200" or width="50%"
The width of the line can be expressed in pixels or as a percentage of the container - eg window or table cell.

Height
height="5"
The height of the line can be expressed in pixels

Align
align="left" {or right, center}
The height of the line can be expressed in pixels

Color
color="red" or color="#ff0000"
The color of the line can be expressed as a named color or a hexadecimal number (see Web Colors).

Noshade
noshade
If this parameter is present, the line will not have a three dimensional appearance.

If the parameters above are added to the <hr> tag to give:
<hr width="50%" size="10" align="center" color="#00ff00" noshade>
the result is:

The <hr> tag should be used sparingly as it splits a web page horizontally and not often recognised as a good design feature.

<br>,<nobr> and <wbr> tag

The <br> tag is use to insert a line break. A line break will always occur at this point.

The <nobr> tag will ensure no line breaks occur until the </nobr> tag is reached. This will give some very wide pages if you forget to use the end tag, so be careful
