🌐 HTML/CSS Cheat Sheet
Complete reference for HTML tags, CSS properties, Flexbox, Grid, selectors, and common web development patterns.
📖 About HTML & CSS
HTML (HyperText Markup Language) provides the structure of web pages, while CSS (Cascading Style Sheets) controls the visual presentation. Together they form the foundation of every website on the internet. HTML5 introduced semantic elements like <article>, <nav>, and <section> that improve accessibility and SEO.
Modern CSS includes powerful layout systems like Flexbox (for one-dimensional layouts) and Grid (for two-dimensional layouts), as well as features like custom properties (CSS variables), media queries for responsive design, and animations/transitions for interactivity.
❓ Frequently Asked Questions
Use Flexbox for one-dimensional layouts (rows OR columns) — navbars, card rows, centering content. Use Grid for two-dimensional layouts (rows AND columns simultaneously) — page layouts, dashboards, image galleries. Many layouts benefit from both: Grid for the overall page structure and Flexbox for components within grid cells.
Semantic elements describe their content's meaning, not just appearance. Examples: <header>, <nav>, <main>, <article>, <section>, <aside>, <footer>. They improve accessibility (screen readers), SEO (search engines understand page structure), and code readability. Always prefer semantic elements over generic <div>.
