Did you know there’s an imagesrcset attribute you can put on link rel="preload" as="image" (along with an imagesizes attribute)?
I didn’t. (Until Amber pointed this out.)
Trys describes exactly the situation where you really do need to use the Shadow DOM in a web component—as opposed to just sticking to HTML web components—, and that’s when the component is going to be distributed and you have no idea where:
This component needed to be incredibly portable, looking great on any third-party website, in any position, at any viewport, with any amount of content. It had to be a “hyper-responsive” component.
This is excellent! A free web book (it’s a book! it’s a website!) that teaches you how to make a website from scratch:
I feel strongly that anyone should be able to make a website with HTML if they want. This book will teach you how to do just that. It doesn’t require any previous experience making websites or coding. I will cover everything you need to know to get started in an approachable and friendly way.

Some lovely HTML web components—perfect for progressive enhancement!
Scott gives a thorough step-by-step walkthrough of building an HTML web component, in this case for responsive video:
In this post, I’m going to talk briefly about responsive video, but most of the post will be about using HTML web components to extend native video behavior in very helpful ways. But even if you’re not particularly interested in video development, stick around as I’ll demonstrate how to build an HTML Web Component to progressively enhance anything you need.
This is an interesting idea from Scott—a templating language that doesn’t just replace variables with values, but keeps the original variable names in there too.
Not sure how I feel about using data- attributes for this though; as far as I know, they’re intended to be site-specific, not for cross-site solutions like this.
Naming custom elements, naming attributes, the single responsibility principle, and communicating across components.
Mobile Safari doesn’t support the min and max attributes on date inputs.
A lazy option for responsive images is at hand.
The joy of getting hands-on with HTML and CSS.
Why do browsers that don’t implement stylesheet switching still download alternative stylesheets?
