This lesson

This lesson teaches Responsive hide and show—the ideas, syntax, and habits you need before moving on in Tailwind CSS.

Traffic is predominantly mobile—layouts that only work on desktop fail users and metrics.

You will apply Responsive hide and show in contexts like: React/Vue/Next apps, marketing sites, design systems, and rapid prototypes where consistency and speed matter.

Read the lesson, edit HTML/CSS in the playground, press Run to preview, then answer the lesson MCQs.

When the previous lesson's MCQs feel easy and you can explain Responsive hide and show in your own words.

Toggle visibility with hidden, block, flex, and responsive pairs like md:flex + md:hidden. Classic pattern: hamburger visible on mobile, horizontal nav on desktop.

Accessibility caution

Hiding with display:none removes content from the tab order. Mobile menus need keyboard focus traps and aria-expanded—utilities handle visuals, not behavior. Compare Utility CSS hide/show patterns.

Self-check

Write classes for a nav hidden on mobile, flex on md+.
What is missing if you only toggle hidden without JS for a menu?
