Back to good old browser default style sheets again. In order to ensure your page content sits
exactly as you desire on all browsers and doesn’t inherit browser defaults, it is important to
consider resetting the page margin and padding in the body selector.
Netscape and IE place a default margin of 8px around the <body> element. The Opera browser
confuses things further by applying a default padding of 8px. Therefore, until all browsers agree
and can settle on either margin or padding to provide this default spacing, it is recommended
that margin and padding be given the values you desire in the body selector:
/* Define default values for the whole site */
body {
margin: 0;
padding: 0;
}
Obviously values of 0 will remove the default spacing entirely, so it may be that you prefer
to set the margin to 10px, 20px, or whatever you need.
Other methods are available that will reset all margins and padding to a defined value that
is inherited throughout unless you declare otherwise. Such methods should be used with caution however, as all headings, paragraphs, lists, and so on will also inherit the value, and if the value
is 0, you might end up in trouble, with all of your page elements bunched together. This would
then require margin and/or padding values to be declared for all headings, paragraphs, and other
elements that typically have sensible default spacing values.
