How to create a Shrinking Sticky Header in Elementor with GSAP
SHARE
What does this code do?
- Header Shrinking: Reduces the height of the header while adding a translucent background and a blur effect.
- Logo and Button Scaling: Scales down the logo and button for a more compact appearance.
- Navigation Scaling: Shrinks the entire navigation menu to match the smaller header.
- Menu Link Color Change: Changes the color of the menu links as you scroll for better contrast.
- Mobile Menu Toggle: Scales down the mobile menu toggle button to align with the overall shrinking effect.
Tips for Adjustements:
startandendvalues: Adjust these values to control when the animation begins and ends.- Custom Colors: Replace
#FFFwith any color code to match their design. - Scrub Setting: Experiment with
scrub: 1to fine-tune the scroll-linked animation smoothness.
