Max’s demo is really clever and features lots of interesting web component related techniques.
I came up with this demo of a book store. Each of the books is draggable and can be moved to one of three sections, with varying available space. Depending on where it is placed, different styles will be applied to the book.
Scott Jehl has taken a refreshingly Progressive Enhancement -centric look at Web Components.
this pattern provides a nice hook for adding progressive enhancements to already-meaningful HTML contained in these custom elements, leaving them resilient in the case of of script loading failures and allowing the page to start rendering before the JS happens to run.
GOV.UK’s guidance on developing using progressive enhancement is pretty great in all departments. It begins with this solid advice:
Over the last couple of days I’ve witnessed a good example of progressive enhancement “In Real Life”. And I think it’s good to log and share these validations of web development best practices when they happen so that their benefits can be seen as real rather than theoretical.
In web development it’s useful when we can say “if the browser supports X, then we know it also supports Y”.
Who said navigation has to be in the header of every page? If your front end is extremely lightweight or if you have a long list of menu items to display in your navigation, the most practical method might be to create a separate page to list them all.
We’re not going to try to replicate everything that the browser does by default with a native select element. We’re going to literally use a select element when any assistive tech is used. But when a mouse is being used, we’ll show the styled version and make it function as a select element.
Here’s a brilliant discussion between Gerry McGovern and Jeremy Keith on that problem, suggesting tactics to help fix things such as performance budgets, introducing tactics at the design stage to mimic slow connections and other access constraints, optimising for return visits, progressive enhancement and more.
In the same vein as Jeremy Keith’s recent blog post, Hydration, which calls out some of the performance and user experience problems associated with current Server Side Rendering approaches, I think Jake Archibald is absolutely bang on the money here.
The situation we have now is the worst of both worlds: server-side rendering followed by a tsunami of hydration. It has a whiff of progressive enhancement to it (because there’s a cosmetic separation of concerns) but it has none of the user benefits.
A disclosure component is the formal name for the pattern where you click a button to reveal or hide content. This includes things like a “show more/show less” interaction for some descriptive text below a YouTube video, or a hamburger menu that reveals and hides when you click it.
My name is Laurence Hughes and I’m a perfectionist. But I’m working on it.
