On the Responsibility That Comes with Good JavaScript Support

HTML and CSS and the 2019 Web Almanac

The HTTP Archive’s Web Almanac is fantastic because it provides us with data about how we build what kinds of websites. While the release of the 2019 Almanac has been accompanied by some analysis, I had found it interesting to interpret the data, too.

The typical reason for why professionals don’t have their own websites is that they don’t want to make the commitment, and yet that misses how the disadvantages people see are actually advantages. Renewed thoughts on how running your own website is an asset.

Upgrade Your HTML (the Booklet)

I’ve written a very short book on improving HTML code: Upgrade Your HTML. Upgrade Your HTML is about one thing: Picking examples of HTML in the wild, and explaining how to make that code better. Kindly. Constructively. Thoroughly, as finding a balance between detail and brevity permits.

On Writing Better Markup

As HTML is so important and yet also so easy, everyone writes HTML, and everyone says they can write HTML. And with that they don’t just mean they are able to write HTML, but that they write good HTML, where “good” means “high quality.” That would be great news.

“Must Work Without JavaScript”

That websites should work without JavaScript has a long professional tradition, and for apps much the same has been asked for. Yet with the success and ubiquity of scripting, how relevant is it to make sure sites and apps “work without JavaScript”?

When to use img, img@srcset, and picture and source

I’ve disliked srcset and the whole family of ideas around it from the start because doing the same thing for the same purpose several times has usually looked like too much DX cost for too little UX gain to me. Two angles at what to use when.
