Values are the choices you make when you change the property of an element. If red value then color was a property. Let's assume that you are changing the color of text enclosed in paragraphs (the p tag) tags to be blue, OK? The CSS code would look like this:
p {color: blue}
In this example code above the property in point is color. Properties can be anything from border-width to vertical-align.The value of the property (color, in this case) is blue. So, in that CSS example above, the entire line of code is a rule. A rule has two basic parts - a declaration and a selector. The selector is the HTML tag which will be affected by the rule. In this case the selector is the p tag. The declaration is the part of the rule that states just what is happening to what. The declaration consists of the previously-mentioned property and value, seperated by a colon (:).
Multiple declarations must be seperated by semicolons (;). Look at this example:
sub {color: fuschia; font-size: 12pt; font-variant: uppercase}
Notice the red semicolons. Also, units of measurement are commonly used as values.
