This is a very brief reference sheet than an exhaustive list of CSS terms: it is intended to provide you with a way to look up the information you’re most likely to need right away. For detailed information about CSS syntax, selectors, and properties, visit the W3C’s CSS tutorial pages at http://www.w3schools.com/css/.
A CSS stylesheet is essentially a group of rulesets. Rulesets are made up of three
things:
See next page for more detailed discussion of each
A selector is the way you identify the elements or groups of elements that will be affected by your style information. A selector may be simply the name of an element, or they may take into account the nesting of the element, or a specific attribute value.
Here’s a list of the most common selectors and their syntax.
Here’s a list of common properties and their most common
kinds of values. Note that some properties (especially those
that govern size) can be measured in several different ways.
Some of the measurements are in absolute units such as pixels;
others are relative to the font size (for instance, ems), and
others are relative to the surrounding text (for instance,
percentages or larger
or smaller
).
