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.

CSS: When to Use Logical Properties
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…

Upgrade Your HTML (the Booklet)
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.

On Writing Better Markup
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.

The Developer’s Fallacy of Close Collaboration With Designers
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.

“Must Work Without JavaScript”
That websites should work without JavaScript has a long professional tradition, and for apps much the same has been asked for. Yet with the success and ubiquity of scripting, how relevant is it to make sure sites and apps “work without JavaScript”?

Optional HTML: Everything You Need to Know
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.

Sources 2019
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.

When to Use “img,” “img@srcset,” and “picture” and “source”
I’ve disliked 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.

Image Compression: How to Super-Easily Set Up Automated Base Optimization
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.

The Problem With Web Development Checklists, or: The Frontend Checklist, Revised
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).

3 Reasons Against Ad Blockers
Ad blockers are popular. Yet, they’re also a problem. They’re a problem that can be broken into three sub-problems, sub-problems that speak not only against the use of ad blockers but argue against their existence.

Understanding Image Compression: Tooling and Context
Image compression plays an important role in performance optimization. It seems straightforward but is a little deceptive, however, because it consists not of one but two parts—and it’s usually lack of understanding of one part that causes problems.

How Can We Make Website Maintenance Work More Visible?
The maintenance and maintainability of websites is a much neglected topic. This is problematic because: We cannot not maintain. Yet primarily we may deal with a visibility problem that we could explore more options for.

199 Love Haiku (the Book)
In 2016, I wrote 1,000 short poems, haiku-style. I wrote those poems to challenge myself as a writer. I launched a website for the haiku and I shared the story. Today, I’ve published the 199 haiku that a few friends and I liked the most as a book.
Print Styling, the 3 Basics
Many sites are not prepared for print, and yet our users print, and they save through print. Therefore: Have a print style sheet, and be it a negative one. Hide what’s not usable or useful. Always test, and tweak when you want better.

Optional “@lang”
The lang
attribute is one of HTML’s global attributes. If one doesn’t simply take it for granted, it begs a number of questions—and these suggest to drop W3C requirements around it, and to demand software to do the job.

HTML and Performance: Leave Out Optional Tags and Quotes
As experts we should know what code is optional and leave it out, and our production systems should do a better job assisting us with that. After all the years of neglecting basic HTML optimization, let’s think about taking the next step and not ship optional HTML markup.
