Summary of Animate On Scroll With Just 3 LINES Of CSS (No Libraries Needed)

The video demonstrates how to create smooth animations on scroll using only three lines of CSS, without the need for any libraries. The process involves creating a view container with block elements that will be animated based on the scroll position.

Key Concepts and Steps:

• Initial Setup:
  • Create a view container and add block elements of varying sizes and colors.
  • Define an animation called "appear" that sets the opacity to 0 and scales the elements to 0.5 initially, then transitions them back to opacity 1 and scale 1.
• animation Triggering:
  • Initially, the animation occurs when the page is reloaded. To trigger animations on scroll, the duration value is removed, and the animation-timeline property is set to "view," ensuring animations happen only when elements are visible on the screen.
• animation Completion:
  • The video addresses an issue where animations complete prematurely as elements exit the viewport. The animation-range property is adjusted to "entry Z," which allows animations to complete as elements enter the viewport.
  • The optimal value for the animation range is discussed, suggesting the use of "cover" to ensure animations complete when elements reach 40% visibility in the viewport.
• Experimentation:
  • Viewers are encouraged to experiment with different animations, such as changing from scale to translation or using clip-path animations where elements grow in width and height as they scroll.
