Articles on the craft of web development, particularly on HTML and CSS optimization.
HTML Concepts: Constraint Validation
When a form element has attributes that define requirements for the element’s value, then these requirements—constraints—are being validated by the user agent. On the validation of constraints, validity states, and a link to CSS.
CSS: “:has()” and the Lost Paradigm
On the :has() pseudo-class and the forgotten school of ID- and class-less development.
The 3-Second Frontend Developer Test
“Do you validate?” Be a frontend developer who ships valid HTML and CSS; hire frontend developers who ship valid HTML and CSS. End the time of unconditionally accepted sloppiness in professional frontend development.
Use the “i” Element, and Use It Appropriately
“Use em instead of i” is in the Top 25 of bad advice you can get in HTML development. The two elements have different meanings, the blunt rule ignores all context, and i is a valid element with legitimate use cases.

HTML Concepts: The “Nothing” Content Model
There’s a content model in HTML that contains—nothing. Details on what this means, and how it relates to “empty” or void elements.
Reasons to Listen to Whom You Don’t Agree With

After a 20-year break, a collection of settings and thoughts on Counter-Strike.
98% of the Top 100 U.S. Websites Use Invalid HTML (in 2021)
Is frontend development in the bad shape it’s said to be? Is it hyperbole when frontend developers are accused of poor quality work? When you look at the code of the most popular websites, the answer is clear.
Upgrade Your HTML III

HTML Concepts: “Body-Ok”
“body-ok” relates to link type keywords, and denotes what link elements are okay to be used in the document body.
Code in Quarantine
In the current paradigm, we often work with components and have a 1:1 relationship of HTML to CSS. This makes maintenance more predictable. However, it also pronounces the problem of rarely used code—which can be useful to put in quarantine.
The Choice to F Up
On the things we are doing and not doing, how these things are not and cannot be accidents, and how it all revolves around choice.
33 Additional Web Development Terms You May Not Have Heard Of

5 Tips for Your Next Promotion or Salary Raise
How do you approach promotions and salary raises? Are these tied to a cyclical event or do they depend on your initiative? Do you invest into building your case, or do you wing it? Here are a few ideas on what can improve your position and chances.

HTML puts elements into content categories. This article serves as a boring, brief, but updated overview over the broad and overlapping categories of HTML, and which elements fall into them.
In Critical Defense of Frontend Development
The field of frontend development is in another crisis, largely due to an incomplete, misinterpreted definition and a bizarre mess created by “web development as a commodity” and “web development as software development.” How frontend development is more than development, and what we can (and should) do.

2020 has been a strange year, a year of challenges, but overall a—good year. Personal notes, professional highlights, a few numbers.
Ignore AMP
In 2018, my recommendation was to avoid AMP, to use AMP for the most relevant pages, or to use AMP only. In 2020 my recommendation is to ignore it, because AMP largely appears meaningless now. Upgrade Your HTML II gives an opinionated idea why.

About Me
I’m Jens Oliver Meiert, and I’m an engineering manager and author. I love trying things, sometimes including philosophy, art, and adventure.
As an expert in web development, 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, the Upgrade Your HTML series, as well as The Web Development Glossary).
In philosophy I’m most interested in metaphysics (even in How to Work on Oneself). When it comes to art I play with photography. For adventure I enjoy exploring both places (Journey of J.) and activities (100 Things I Learned as an Everyday Adventurer).
