On the Responsibility That Comes with Good JavaScript Support

According to our data, the classic idea of making sure websites and apps work without JavaScript being enabled is dead; when we look only at support requirements, this was the end of the story. It’s not, however, when we employ a broader look at JavaScript and its misuses.

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

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.

Biography

Jens Oliver Meiert, on April 29, 2020.

I’m Jens Oliver Meiert, and I’m a web developer and author. I love trying things (sometimes involving philosophy, art, or adventure).

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

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).
