/ Image Placeholder DIV

This is a quick snippet I already wrote about under Image Optimization but decided to revisit in order to make it totally image-less (in the placeholder state).

The change, in a gist, lies in using a button element instead of an img. The inner text used to present the reader with the dimensions and filesize of the image they are about to load - this will require some server-side code which I may add here in the future.

You can, at this point, just use a pure CSS solution.

First, we need the button. Note we're using data-src to store the URL of the image. The text inside the button can be static ("Click to load") or dynamic ("350x150, 10kB").

<button class="loadimg" data-src="https://via.placeholder.com/350x150">Click To Load 🖼️</button>

Next up is the code that makes it work. This requires a little bit of JS:

const images = document.querySelectorAll("button.loadimg");
  images.forEach(function(image) {
      image.addEventListener('click', e => {
        var i = document.createElement('img');
        i.src = e.target.dataset.src;
        image.removeEventListener('click', e);
