ELI5: What’s the difference between internet browsers. Aside from appearance and customization, what causes the mechanics of different browsers to work better on certain websites?

So, technically the components of websites (HTML, CSS, and JavaScript primarily) are standardized, but it's still up to the browser makers to actually implement those standards. These standards are being updated all of the time, so some browsers that are quicker to update and designed to be fully featured (e.g. Chrome, FireFox, Edge) will support these updates while older browsers or ones designed to be light won't support these updates. A web programmer has to know what sort of features are supported while writing code in order to support their target web browsers. Sometimes programmers will target a specific browser and not update their website to work well with other browsers.
