HTML Explained
Horizontal Rule
A Horizontal Rule tag <HR> draws a line across the page.
You can control the thickness of the line by using <HR SIZE=n>, where n is the thickness, in the case below 10.
You can also control the width of the line by using <HR WIDTH=n>, where n is the width in pixels, in the case below 100.
The width can also be set to a percentage of the width of the page by using <HR WIDTH=n%>, where n is the percentage, in the case below 50.
The WIDTH and SIZE can be combined, for example <HR SIZE=10 WIDTH=100>.
Headers
Header tags come in six sizes, 1-6, where 1 is the largest, and 6 is the smallest. The header is contained within its own paragraph. Header tags are used as follows:
<H1> This is header size 1 </H1>
<H3> This is header size 3 </H3>
<H6> This is header size 6 </H6>
