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.

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”

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.

3 Reasons Against Ad Blockers

Ad blockers are popular. Yet, they also appear to be a problem. They appear to be a problem that can be broken into three sub-problems, sub-problems that may speak not only against the use of ad blockers but their very existence.

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.

Print Styling, the 3 Basics

Many sites are not prepared for print, and yet our users print, and they save through print. Therefore: Have a print style sheet, and be it a negative one. Hide what’s not usable or useful. Always test, and tweak when you want better.

Optional @lang

The lang attribute is one of HTML’s global attributes. If one doesn’t simply take it for granted, it begs a number of questions—and these suggest to drop W3C requirements around it, and to demand software to do the job.

HTML and Performance: Leave Out Optional Tags and Quotes

As experts we should know what code is optional and leave it out, and our production systems should do a better job assisting us with that. After all the years of neglecting basic HTML optimization, let’s think about taking the next step and not ship optional HTML markup.

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).
