This page documents various CSS elements that are useful to know when working in the article and template namespaces. For information about how to use them, see:

• border-collapse:collapse This style will eliminate 3-d style borders created by the border attribute and collapse them in 1px wide borders. This property will override cellspacing! To define similar whitespace, use the border-spacing property (although it is not possible to have both border-spacing and border-collapse for the same table).

• float:right and clear:right These styles are used to move a table to the right-hand side of the screen. Float right is equivalent to align="right" The clear code property makes it impossible for the movement to be blocked by another box or picture: the template will automatically move under it.

• margin:0 0 0.5em 1em; This style prevents text from running straight to the template by saving blank space. It should be used on boxes which are floated right (using float: right;).
  • margin:0 1em 0.5em 0; This performs the same function as the style directly above, but should be used for boxes which are floated left (using float: left;).
