Articles on the craft of web development, particularly on HTML and CSS optimization.
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
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.
9 TILs that I applied to my personal projects.
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—
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?
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.
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
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.
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.
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 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—
“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.”
“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.”
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.
Notes, refreshers, as well as an alternative overview over Scrum.org resources for PAL certification.
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.
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.”
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.
Another year, another retrospective. Factoids and data on life and work.
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.
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.
Leadership is important, and it can be learned.
Logical properties are great and long overdue. They are great because they solve an ugly problem of international, multi-directional web development in that directionality does not need to affect your writing and managing of CSS anymore…
Random improvements and notes around compression and caching, content security and feature policies, IndieWeb markup, protocols in links, entity references, image formats, and ISBNs in URL paths.
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).
