Define "cascade" as it relates to CSS and explain the CSS cascading mechanism.
What will be an ideal response?
One of the fundamental features of CSS is that style sheets cascade. This means that multiple style sheets and style rules can apply to the same document. HTML authors can attach a preferred style sheet, while the reader might have a personal style sheet to adjust for preferences such as human or technological handicaps. However, only one rule can apply to an element. The CSS cascading mechanism determines which rules are applied to document elements by assigning a weight to each rule based on the following three variables:
Specificity of the selector
Order of the rule in the style sheet
Use of the !important keyword
