Introduction to CSS hitesh kumar 1 Cascading Style Sheets CSS stands for Cascading Style Sheets Styles define how to display the HTML elements CSS rule, is made up of two parts: 1. Selector 2. Declaration 1. Selector: which indicates which element or elements the declaration applies to (if it applies to more than one element, we can have a comma - separated list of several elements) 2. Declaration: which sets out how the elements referred to in the selector should be styled The declaration is also split into two parts, they are separated by a colon: 1. Property: which is the property of the selected element(s) that we want to affect, in this case the width property. 2. Value: which is a specification for this property; in this case it is that the table cells should be 36 pixels wide. Here is an example of a CSS rule that applies to several different elements (in this example, the < h1 > , < h2 > , and < h3 > elements). A comma separates the name of each element that this rule will apply to. The rule also specifies several properties for these elements with each property - value pair separated by a semicolon. Note how all the properties are kept inside the curly braces: h1, h2, h3 { font-weight:bold; font-family:arial; color:#000000; background-color:#FFFFFF; } Here three heading elements named in the selector ( < h1 > , < h2 > , and < h3 > ), and this rule headings are written in a bold Arial font in black with a white background. Note: If there is only one property - value pair in the declaration, we do not need to end it with a semicolon. However, because a declaration can consist of several property - value pairs, and each property - value pair within a rule must be separated by a semicolon.
