How The New POSITIONS Will Work in MODERN CSS
In this video, you’ll learn everything about the new CSS positioning system that’s changing how modern web layouts work.
Developers have been using position: absolute and JavaScript to align dropdowns and tooltips for years — but that’s now old news.
With anchor-positioning, @position-try, position fallbacks, and the Popover API, you can now build smart dropdown menus and popovers that never leave the screen — using only HTML and CSS.

In this CSS tutorial for 2025, we’ll break down all the latest updates step by step:
• How anchor positioning connects elements using the anchor() function.
• How @position-try and position-try-fallbacks automatically pick the best placement.
• How position-area defines preferred zones for smarter layouts.
• How the Popover API and the new popovertarget attribute let you toggle dropdowns and tooltips without JavaScript.
You’ll learn to combine all of this to create responsive, dynamic UI components that adapt to the viewport — the kind of CSS that used to require complex JavaScript logic.
