Articles on the craft of web development, particularly on HTML and CSS optimization.
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.
:has() pseudo-class and the forgotten school of ID- and class-less development.
“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.
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.
Content security policies. Promotions. Words. Tracking. Link types. Meta information. VG WORT. Social markup. Living the dream.
There’s a content model in HTML that contains—nothing. Details on what this means, and how it relates to “empty” or void elements.
Our culture has become one of canceling, of reacting to what we disagree with and whom we dislike by ignoring, unfollowing, blocking, banning, ostracizing. Camouflaged as non-violent protest, it can well be passive-aggressive intolerance of views and people.
There may be a time when you’ll feel “too old” for web development. When you begin to feel that, here are a few thoughts. They might not be all you need but—maybe they are of use.
After a 20-year break, a collection of settings and thoughts on Counter-Strike.
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.
If you care about HTML as a craft, if you consider yourself an HTML minimalist, if you believe in pushing for boundaries (and sometimes overdoing it), then this is a right book (and a right book series) for you—with 10 fresh examples from the field that get inspected and improved.
Ideas and principles for managing engineering teams: From “competence, caring, conviction” and googliness to systems and processes to communication and delegation to team focus and health to trust and humility.
“body-ok” relates to link type keywords, and denotes what
link elements are okay to be used in the document body.
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.
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.
As you know, Web Development has its own, special vocabulary that easily consists of several thousand terms. Do you like to try your knowledge again, on how many of the following 33 terms you know?
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.
With more and more software and regulation limiting the data that we pay with for contents and services, we are, in a way, requiring these contents and services to be made truly free. This doesn’t appear sustainable, and the Web is likely to change.
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.
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.
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.
Would it still be useful to read the HTML 3.2 specification—from 1997? A few observations.
If you care about HTML as a craft, if you consider yourself an HTML minimalist, if you believe in pushing for boundaries (and sometimes overdoing it), then this is a right book (and a right book series) for you—with 10 new examples from the field that get inspected and improved.
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).
