How It Works
CSS is written in rulesets that consist of selectors and declarations. Selectors specify which HTML elements to style, and declarations define how to style those elements. The declarations are enclosed in curly braces and consist of property-value pairs.
Key Components
- Selectors: Identify which HTML elements to style (e.g.,
p
,#id
,.class
). - Properties: Define what aspect of the element to style (e.g.,
color
,font-size
). - Values: Specify the style to be applied (e.g.,
red
,16px
).
