display

This property specifies an element's display type and can override an element's defined display type. For example, block-level elements can be redefined as inline elements so that extra lines will not be placed between them. The allowed values for display under CSS1 are inline, block, list-item, and none. The value of none completely removes an element from the document tree and unlike the hidden value of the visibility property, none does not preserve an element's canvas space.

CSS2 adds

run-in, compact, marker, table, inline-table, table-row-group, table-header-group, table-footer-group, table-row, table-column-group, table-column, table-cell, and table-caption.

Examples

p {display: inline;}
b {display: block;}
.removed {display: none;}
