It’s the skeleton. Without clear structure and accessible markup, everything else wobbles.
How to Improve HTML5 Skills
Semantics first: Use the right elements for the job. It helps screen readers, SEO, and humans scanning your code.
Accessible by default: Landmarks, labels, alt text, keyboard paths. Ship inclusive experiences.
Form mastery: Native inputs, validation, helpful error states—lightweight and user-friendly.
Responsive mindset: Structure content that adapts gracefully across devices and densities.
Performance basics: Sensible markup, defer what you can, keep the DOM lean.
Build often: Recreate pages, refine semantics, and test with assistive tech.
Simple HTML, done right, makes everything downstream easier.

6. CSS3
CSS3 styles the experience—layout systems, animations, and responsive rules that translate ideas into interfaces.
Why It's Important
Good styling isn’t decoration. It’s clarity, hierarchy, and usability across screens and contexts.
How to Improve CSS3 Skills
Core layout fluency: Box model, Flexbox, Grid. Compose complex layouts with minimal hacks.
Responsive design: Thoughtful breakpoints, fluid spacing, container queries where appropriate.
Scalable structure: Use naming conventions and component patterns that survive growth.
Modern tooling: Preprocessors or PostCSS, variables, and build pipelines to keep styles consistent.
Motion with purpose: Transitions and animations that guide attention, never distract.
Practice relentlessly: Rebuild real sites; aim for pixel trust, not pixel perfection.
When CSS snaps into place, the whole product feels calmer.
