This lesson

An orientation to this CSS lesson—scope, vocabulary, and what you will practice next.

You need a clear map of the CSS track so later lessons do not feel like isolated tricks.

You will apply RWD Intro in contexts like: All browser UIs, component libraries, marketing sites, and many native apps that reuse web views.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs. Also open the interview prep blocks.

Start here at the beginning of the css track before skipping ahead.

RWD intro emphasizes fluid containers, flexible media, and adaptive components.

Q: Fluid vs fixed layout?
A: Fluid scales with viewport; fixed stays rigid and can overflow.
Q: Why start with content priority?
A: Small screens force essential information hierarchy decisions.
Q: RWD and accessibility connection?
A: Better zoom/reflow behavior directly improves accessibility.

Tip: Design mobile-first: base rules, then min-width media queries.
