This lesson

This lesson teaches CSS Buttons—the ideas, syntax, and habits you need before moving on in CSS.

Without a solid grasp of CSS Buttons, you will repeat mistakes in CSS exercises and on real pages or scripts.

You will apply CSS Buttons 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.

When intermediate lessons feel comfortable and you are ready for production-style trade-offs.

Button styling should balance brand aesthetics with clear states and accessibility guarantees.

Button state system

  • Default, hover, active, disabled.
  • Focus-visible ring for keyboard users.
  • Consistent size and spacing variants.

Important interview questions and answers

  1. Q: Most common button styling bug?
    A: Missing focus-visible state after custom theme styling.
  2. Q: Why avoid low-contrast disabled buttons?
    A: They can become unreadable and ambiguous.
  3. Q: Should link-looking buttons be anchors?
    A: No, actions should remain button semantics.

Practice: Change one property in the playground and observe cascade + layout in DevTools.
