Re: Length of the page
Because every browser has a different default setting for html tags your page is naturally doomed to look slightly different amongst different browsers.
You can get around this with what is called a CSS Reset.
Possibly the most popular one can be found here:

When you link to your CSS, first link to the CSS RESET. It will wipe the defaults of the user's browser and give you full control over how your website will be displayed.
There is a catch. You will have to start using CSS to define things like Line-height:; and add padding to almost everything such as in tables.
There are many new CSS commands to use because normally Browser defaults are acceptable.
However it is wel worth doing if you really want the unity.
