Css, How to

When designing a CSS based website it is very useful to understand Margins. I have found that it is much easier to deal with browser compatibility when  one uses proper margin styles. Trying to set a top: -10px seems to cause browser issues that can be easily avoided by using margin-top:-10px.

Margins can be applied to the outside of any block level or inline element. They create space between the edge of an element and the edge of any adjacent elements.

Margins can be applied to the individual sides of an element.

Margins can also be used with a single short tag. If one value is set this value will be applied to all sides of the element.

If two values are set, the first value will be applied to the top and bottom of the element while the second value will be applied to the left and right margins.

If three values are set the fist value is applied to the top, the second value is applied to the left and right and finally the third value is applied to the bottom.

If for values are set the first value is applied to the top, the second value is applied to the right, the third value is applied to the bottom and the forth is applied to the left.
