Get the most from each lesson’s live editor with a deliberate loop—same habits that transfer to real Bootstrap projects.
Recommended workflow
- Read the concept section before touching code.
- Change one class group at a time (grid columns, then spacing, then component variant).
- Resize the preview pane to test responsive breakpoints (
col-md-*,d-lg-none). - Use browser DevTools to inspect which Bootstrap rule wins when debugging.
- Reset the editor if you drift too far from the lesson goal.
Review CSS cascade if custom CSS and Bootstrap utilities conflict—your overrides need equal or higher specificity, or CSS variables Bootstrap exposes.
Self-check
- Why change one class group at a time during learning?
- What DevTools panel confirms a Bootstrap class is applied?
Challenge
CDN smoke test
- Confirm Bootstrap styles apply (add
btn btn-primary). - Open DevTools and verify CSS loads from the CDN link.
Done when: a styled button appears without a local build step.
