Description:
On the landing page of OpenCRE, the scroll-down arrow button remains visible even after reaching the bottom of the page.
For a better user experience, the arrow button should be hidden once the user reaches the bottom of the page.
Expected Behavior:
The scroll-down arrow button should disappear when the page is fully scrolled to the bottom.
Actual Behavior:
The arrow button is still visible at the bottom of the page.
Suggested Improvement:
Add a condition to detect when the user reaches the bottom of the page and hide the arrow button accordingly.
