How to Prevent Fixed Elements from Overlapping the Footer?

Scroll-Proof Fixed Footers

When using fixed-position elements, it can be challenging to avoid them overlapping with the page footer. This issue is commonly encountered with floating share buttons or other UI elements.

One effective solution to this problem involves continuously monitoring the position of the fixed element as the user scrolls. By adding a jQuery event listener to the document's scroll event, we can dynamically adjust the positioning of the element.

Here's a detailed explanation of the solution:

1. Offset Checking: Use jQuery's offset() function to retrieve the current position of the fixed element on the page.
2. Absolute Positioning: If the bottom edge of the fixed element (calculated by offset plus height) intersects with the top edge of the footer (minus 10px to provide a buffer), set its position to absolute using CSS.
3. Fixed Position Restoration: When the user scrolls up and the fixed element is no longer in danger of overlapping the footer, restore its position to fixed.
4. Parent Element Positioning: Ensure that the fixed element's parent element is a sibling of the footer to ensure proper positioning.

By implementing this solution, you can effortlessly prevent your fixed elements from scrolling over the footer, maintaining their visibility while ensuring a clean and seamless user experience.
