How to Improve HTML5 Skills

1. Use semantic elements: <header>, <main>, <section>, <article>, <nav>, <footer>.

2. Craft accessible forms with proper input types, labels, and validation.

3. Embed media the modern way: <video>, <audio>, captions, and fallbacks.

4. Lean into APIs: Canvas, Local Storage, Drag-and-Drop, Geolocation—use them thoughtfully.

5. Structure for responsiveness from the start; content first, layout second.

6. Mind accessibility: landmarks, alt text, headings, and ARIA where needed.

6. CSS3

CSS3 shapes the look and feel—layouts, motion, polish. It’s where usability and aesthetics meet.

Why It's Important

Great ideas stumble without solid presentation. CSS3 brings responsive layouts, accessible color systems, and subtle animations that guide the eye.

How to Improve CSS3 Skills

1. Understand the cascade, specificity, inheritance, and the box model deeply.

2. Design with modern layout tools: Flexbox and Grid for sane, fluid structures.

3. Adopt responsive strategies: fluid units, media queries, and container queries.

4. Use custom properties (CSS variables) for themes and consistency.

5. Animate with restraint: transitions, keyframes, prefers-reduced-motion.

6. Organize styles: BEM, utility-first, or another system—just be consistent.

7. Measure performance and accessibility; optimize paints and reflows.

7. Git

Git tracks changes and coordinates collaboration. It’s the safety net and the time machine.

Why It's Important

You’ll experiment freely, recover gracefully, and work with others without trampling one another’s changes. Employers expect it.

How to Improve Git Skills

1. Get fluent with the bread-and-butter: clone, branch, add, commit, pull, push.

2. Branch with purpose. Keep changes focused and merge cleanly.

3. Write commits that tell a story: what changed, and why it mattered.

4. Use .gitignore to keep noise out of history.

5. Learn to resolve conflicts calmly and review diffs like a detective.

6. Explore advanced moves: rebase, cherry-pick, stash, bisect.

7. Adopt a simple workflow (feature branches, pull requests, code reviews) and stick to it.
