How do I implement infinite scrolling in a Blogger template to resemble Instagram's feed?

Implementing infinite scrolling requires JavaScript. You'll need to load more posts as the user scrolls down. Blogger's API can be used to fetch older posts. A common approach is to initially load a set number of posts, then use JavaScript to detect when the user reaches the bottom of the page. When detected, make an AJAX request to the Blogger API to retrieve the next batch of posts and append them to the existing content. Be mindful of performance; load images efficiently (lazy loading is recommended).
