Using CSS,There are three ways to insert CSS into an HTML document: by using an internal style sheet, inline styles, or an external style sheet. An internal style sheet applies to a single page, an inline style to a single element, and an external style sheet to potentially an entire web site.

Grouping,To keep style sheets short and easy to edit, similar rules can be grouped together. This grouping provides several ways to specify a set of related rules.

Relationship Selectors,Relationship selectors match elements based on their relation with other elements. To understand these selectors, it is important to recognize how elements in a web document are related to each other.

Specificity,When more than one rule applies to the same element and they specify the same property, there is a priority scheme that determines which rule is given precedence. In short, CSS gives priority to the rule that has the most specific selector.
