Fixing a Div After Scrolling to It

Problem: How can you ensure that a div remains fixed after scrolling to it, despite its initial position on the page?

Solution:

To achieve this, there are two primary approaches:

1. CSS-Only Method:

   • Utilize the CSS position: fixed property after scrolling to the desired position.
   • This solution is available in modern browsers (see https://stackoverflow.com/a/53832799/1482443 for details).

2. jQuery Method:

   • Listen for the scroll event using jQuery.
   • Determine the desired div's initial position using the offset().top method.
   • Apply position: fixed styling if the scroll position exceeds the div's initial position and revert to position: static otherwise. Here's the jQuery code:

var fixmeTop = $('.fixme').offset().top;

$(window).scroll(function() {

    var currentScroll = $(window).scrollTop();

    if (currentScroll >= fixmeTop) {
        $('.fixme').css({
            position: 'fixed',
            top: '0',
            left: '0'
        });
    } else {
        $('.fixme').css({
            position: 'static'
        });
    }

});

With either approach, you can effectively make a div fixed after scrolling to it. Remember to consider browser support when choosing between the two methods.
