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.

How Running Your Own Website Is Much Better for You Than You Think

The typical argument for why professionals don’t have their own websites is usually 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.

An HTML Optimizer’s Config for html-minifier

Jad (Joubran) asked me about my configuration for html-minifier the other week, and in a hurry I pointed him to the config I had worked out for sum.cumo. In my own projects, however, I work with a different, more ambitious setup.

The cover of “Upgrade Your HTML.”

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.

The Developer’s Fallacy of Close Collaboration with Designers

Working closely with designers makes sense and is awesome, notably for mutual understanding and efficiency. And yet there are also good reasons not to work closely with designers. For developers it’s important, for otherwise foolish, to be aware.

“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”?

Sources 2019

In 2014, for idealistic transparency and enthusiastic link love, I’ve shared the feed sources I was following at the time. I’m still a huge believer in and user of feeds. As I also still like to be transparent I thought to share an update.

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.

Understanding Image Compression: Tooling and Context

Image compression plays an important role for performance optimization. It seems straight-forward but is a little deceptive, however, because it consists not of one but two parts—and it’s usually lack of understanding of one part that causes problems.

Biography

Jens Oliver Meiert, on September 27, 2019.

I’m Jens Oliver Meiert, and I’m a web developer and author. I love trying things, including in the fields of philosophy, art, and adventure.

As a web developer I specialize in getting the maximum out of HTML and CSS, contribute to technical standards, and write books (The Little Book of HTML/CSS Frameworks, Coding Guidelines, and Website Quality Control; On Web Development, CSS Optimization Basics, Upgrade Your HTML).

In philosophy I focus on metaphysics (except in How to Work on Oneself). When it comes to art I mostly play with photography. For adventure I enjoy exploring both places (Journey of J.) and activities (100 Things I Learned as an Everyday Adventurer).

Stay up-to-date? That’s easy, by feed or on Twitter.
