Modern CSS (2010s–Present)

Today, CSS continues to evolve with new specifications and features. Some of the most important modern additions include:

• CSS Grid Layout: A powerful two-dimensional layout system.
• Custom Properties (CSS Variables): Reusable values for colors, spacing, and fonts.
• Advanced Animations with keyframes and transitions.
• Improved Responsive Design with flexible units like vw, vh, and rem.

Modern browsers now have excellent CSS support, reducing cross-browser issues that were common in the past. Developers also use preprocessors (like SASS and LESS) and frameworks (like Bootstrap and Tailwind CSS) to write cleaner and more efficient styles.
