Pseudo-classes & Pseudo-elements

CSS pseudo-classes for targeting element states (:hover, :focus, :nth-child) and pseudo-elements for creating virtual content (::before, ::after).

Responsive Design

Building layouts that work on every screen size -- the viewport meta tag, media queries, mobile-first development, breakpoints, responsive images, and fluid typography.

Selectors

Specificity & the Cascade

How CSS decides which rule wins -- the cascade algorithm, specificity calculation, inheritance, the !important keyword, and cascade layers.

How browsers calculate element sizes using the CSS box model -- content, padding, border, margin, box-sizing, and debugging with DevTools.

Transitions & Animations

CSS transitions for smooth state changes, transform functions (translate, rotate, scale, skew), keyframe animations, timing functions, and performance tips.

Units & Sizing

CSS length units -- px, em, rem, percentages, viewport units, and when to use each one for font sizes, spacing, and layout.
