A element can be hidden by:

display: none
make invisible and occupies no space. (effectively as the element doesn't exist.)
visibility: hidden
maket it invisible, but it still occupies the same space.
visibility: visible
normal.

These are useful especially when used together with JavaScript. For example, for collapsible list, popup tooltip.
