CSS
Cascading Style Sheets.
Definition
Cascading Style Sheets. The language that controls how HTML looks — colors, fonts, spacing, layout, animations. HTML provides the structure, CSS provides the visual design.
Example
h1 { color: blue; font-size: 32px; } — this CSS rule makes all h1 headings blue and 32 pixels tall.
