Articles on high quality web development, especially on HTML and CSS optimization (and, occasionally, on philosophy, art, and adventure).
What is a BHO? Goanna? Hooking? How about a principal box? Or the Ten-Second Rule? Covering almost 2,000 terms ranging from A11Y to Zsh, and including explanations from Wikipedia and the Mozilla Developer Network (MDN), 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—
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 argument for why professionals don’t have their own websites is usually 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’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.
As HTML is so important and yet also so easy, everyone writes HTML, and everyone says they can write HTML. And with that they don’t just mean they are able to write HTML, but that they write good HTML, where “good” means “high quality.” That would be great news.
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.
Web developer, n.: A person who—
Optional HTML can be left out to improve performance, to guide code comprehension, and to hone the craft. An overview over all optional tags, rules around quotes for attribute values, and omissible attribute value defaults, as well as notes on pitfalls and tools.
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.
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.
We’ve all seen approaches to team management and leadership that work, and others that don’t. A brief and scrappy list of the mistakes I’ve witnessed (or committed), together with thoughts on how not to make them.
Setting up image compression tooling is easy—and for those who want to err on the safe side automatically employing lossless compression, it’s even easier with a solution from sum.cumo: Merlin.
Checklists are a great way to make sure nothing gets forgotten, yet they are problematic when they contain items that aren’t important. A few general thoughts and a very specific review of The Frontend Checklist—of which 33 guidelines appear useful, and 41 not (yet).
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).
