I found an image grid that I am using and would like to modify it to load images in HTML instead of js. Here is the original source: https://codepen.io/team/css-tricks/pen/pvamyK.
My desired format for loading images is as follows:
<section id="photos">
<img src="img/single.png" alt="Cute cat">
<img src="img/single2.png" alt="Serious cat">
<img src="img/single3.png" alt="Serious cat">
<img src="img/single4.png" alt="Serious cat">
<img src="img/single5.png" alt="Serious cat">
</section>
