CSS
Cascading Style Sheets
Definition
The language that controls how web pages look, colours, fonts, spacing, layout, animations. HTML provides structure; CSS provides the visual design.
Why it matters
CSS is what makes a website look polished or amateur. Even without coding skills, understanding CSS concepts helps you communicate design changes clearly to developers.
Example
A founder asks her developer to "increase padding, make the button border-radius rounder, and change the hover state to the brand pink", all CSS properties.
