CSS Syntax, Selectors & Specificity
CSS rules consist of a selector (what to style) and a declaration block (how to style it). The browser resolves conflicting styles using the Cascade: specificity scores determine whether an element selector (1 pt), class selector (10 pts), or ID selector (100 pts) wins.
> **Key Takeaway:** CSS (Cascading Style Sheets) applies styling rules to HTML elements using selectors, properties, and values.
