I am new to ajax I want to load images first and then footer but when I am trying to load the images using ajax the footer gets loaded first instead of the images which makes the image overlap the footer. As you can see in the below image.

<!doctype html>
<html lang="en">
  <head>

    <meta charset="utf-8">
    <meta name="viewport" content="width=device-width, initial-scale=1">

    <link rel="stylesheet" href="styles.css" />     
    <title>Image Gallery</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script>
    <script>
        $(document).ready(function(){
        $.ajax({
            url: "js/data.json",
            dataType: "json",
            success: function(data)
            {
                $.each(data, function(i,pic){
                    $("ul.gallery").append("<li><img src='images/square/"+ pic.path + "' alt='" + pic.title + "'></li>");
                });
            },
            error: function() {
                console.log("Picture cannot be loaded");
            }
        });
    });
    </script>
    <style>
        .b-footer{
            background-color: #274472; 
            color:white;
        }
        .gallery {
            list-style-type: none;
            margin: 0px;
            padding: 0px;
        }
        .gallery {
            list-style-type: none;
        }

        .gallery li{
            float: left;
            padding: 30px;
            position: relative;
            overflow: hidden;
        }
    </style>
  </head>
  <body>
    <main class="container">     
        <ul class="gallery">
        </ul>
    </main>
    <footer class="text-center p-4 b-footer">
        This is a footer
        <div>
            <nav aria-label="breadcrumb">
                <ol class="breadcrumb justify-content-center">
                    <li class="breadcrumb-item"><a href="#">Home</a></li>
                    <li class="breadcrumb-item"><a href="#">About</a></li>
                    <li class="breadcrumb-item"><a href="#">Contact</a></li>
                    <li class="breadcrumb-item"><a href="#">Browse</a></li>
                </ol>
            </nav>
        </div>
    </footer> 
  </body>
</html>

Can anyone help me out with how to resolve this issue like how to make the footer to be loaded later after the images are loaded? A correct code can help me.

The simple answer is to remove existing styles for .gallery li and add the below
```
.gallery li {
    display: inline-block;
    padding: 30px;
    position: relative;
    overflow: hidden; }
```

I think your footer would be fine if you added a clearfix class to your main container. The reason is that all your li’s are float left so your footer will overlap the main container.
```
.clearfix::after { 
    content: ""; 
    clear: both; 
    display: block; 
}
```
SUMMARY

The clearfix, for those unaware, is a CSS hack that solves a
persistent bug that occurs when two floated elements are stacked next
to each other. When elements are aligned this way, the parent
container ends up with a height of 0, and it can easily wreak havoc on
a layout.

It’s not an ajax issue you just need to add proper footer CSS here is working solution of your problem just replace footer CSS with this

.b-footer{
                background-color: #274472; 
                color:white;
                position: absolute;
                 bottom: 0;
                width: 100%;
            }
