A single selector

The id determiner can independently promote influence, even if it is not used to create a derivative determiner:

# sidebar {border: 1px dotted # 000; padding: 10px;}

Following this rule, an element with an id of sidebar will have a black dotted border that is pixel wide and will be surrounded by a 10 pixel wide inner margin (padding, internal vacancy). Older versions of Windows/IE browsers will probably ignore this delineation unless you rate the boundary of the element to which the determiner belongs:

Div#sidebar {border: 1px dotted # 000; padding: 10px;} at this point, I believe you have a better understanding of "how to use the CSS id selector". You might as well do it in practice!
