Jens Oliver Meiert’s Blog
Articles on the craft of web development, particularly on HTML and CSS optimization.
People Care
It seems easy these days to lose faith in people. We’re destroying the planet, elect the least competent and least humane of our peers for presidents, kill our own people when we don’t kill people in other countries, etc.—and yet we all care.
A Day Is a Day
On a personal preference for Inbox 0, and doing, delegating, and deferring.
Custom Properties: Questioning :root
For custom properties (aka CSS variables) we got into the habit of declaring variables in a rule with a :root selector. Yet unless you’re working in an environment in which style sheets serve several document types (and roots), question this use of :root.
Love
Love is the essence, love is the emotion. Yet it’s striking how we talk about love, as if there was just one type of love. Aldous Huxley comes to mind, and After Many a Summer Dies the Swan.
Website Optimization Measures, Part X
9 TILs that I applied to my personal projects.
The Anti-Reset
I advise against resets. You don’t need them. (We don’t need them.) Yet what’s the opposite of a reset? Of all resets? The anti-reset. It looks something like this—
33 Web Development Terms You May Not Have Heard Of
Web Development has its own, special vocabulary that easily consists of several thousand terms. Even if you’re an experienced developer you’re unlikely to know all of them. Still, do you like to try your knowledge? How many of the following terms do you know?
On Disclosing Our Salaries
For a year now I’ve been toying with the idea of publicly disclosing my salary, as well as my financial assets. Not because of me, but because I’ve come to believe that this step, if taken by others, too, would be a step towards more transparency.
The 25 Boolean Attributes of HTML
What is a Boolean, what is a Boolean attribute, how does a Boolean attribute work, and what Boolean attributes are there? Meet the Boolean attributes, from allowfullscreen to truespeed.
5 Tips to Get Your Dev Blog Running
If you know what you can deliver, if you keep at it, if you make it easy for your peers, if you talk about the effort, and if you measure and improve and employ a process, you’re likely to do well: thoughts on technical outreach.
The 4 Pillars of Good Embed Code
Embed code is third-party code to be integrated on websites and apps, like ads or social media widgets. There have been many problems with embed code for a very long time. This post covers the essence of what makes for good embed code.
The Web Development Glossary (More Than 2,000 Key Terms for Developers)
What is a BHO? Goanna? Hooking? How about a principal box? Or the Ten-Second Rule? Covering more than 2,000 terms ranging from A11Y to Zsh, and including explanations from Wikipedia and the MDN Web Docs, I’m very happy to release the The Web Development Glossary.
The Frameworks Paradox
The more complex a website, the bigger the need for a framework, the less effective an external framework. This is not new, and not even a paradox because an internal—homemade—HTML/CSS framework is always an option. However—
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.
Highlights from The Crowd (Gustave Le Bon)
“Crowds are only cognisant of simple and extreme sentiments; the opinions, ideas, and beliefs suggested to them are accepted or rejected as a whole, and considered as absolute truths or as not less absolute errors.”
Highlights from An Introduction to Psychology (Wilhelm Wundt)
“There cannot be the least contradiction in the idea that physical and psychical phenomena follow different laws, as long as these laws are not irreconcilable with the actual unity of the psycho-physical individual.”
Round Table
I was late to discover Round Table, but joining this fine service association was one of the greatest decisions and experiences I’ve made in my life. Here’s my story co-founding and accompanying a new table, RT 233 Alster-Milchstraße, for almost four years.
Professional Agile Leadership (PAL) Reminders and Resources
Notes, refreshers, as well as an alternative overview over Scrum.org resources for PAL certification.
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.
If It Can Be Done Using an HTTP Header, Use an HTTP Header
The following is a (slightly modified) chapter from Upgrade Your HTML, which is “all about picking examples of HTML in the wild, and explaining how to make that code better.”
How Running Your Own Website Is Much Better for You Than You Think
The typical reason for why professionals don’t have their own websites is 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.
2019
Another year, another retrospective. Factoids and data on life and work.
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.
When to Open Links in a New Tab
Always open links in the same tab unless doing so 1) could disrupt a process, 2) could risk data loss, or 3) could confuse the user.
On Leadership
Leadership is important, and it can be learned.
Biography
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 appreciate 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).
