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
borderattribute and collapse them in 1px wide borders. This property will override
cellspacing! To define similar whitespace, use the
border-spacingproperty (although it is not possible to have both
border-collapsefor 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
clearcode property makes it impossible for the movement to be blocked by another box or picture: the template will automatically move under it.
Margins and sizes
- 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;).
