Web Development
Website Optimization Measures, Part IX
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.
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.
Definition of Web Developer
Web developer, n.: A person who—
“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 important 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.
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).
Understanding Image Compression: Tooling and Context
Image compression plays an important role for performance optimization. It seems straight-forward 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.
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.
What Happened on Google+, the Web Development Archives
Following a few philosophy posts to be archived, here are past entries related to web development. Nothing more, nothing less.
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.
Google Lighthouse and PWA
A review of Lighthouse’s PWA audits and the PWA category as a whole. Just in time to see it be superseded by Lighthouse 4, the major update that solves some (unfortunately not all) of those issues.
On Performance Visions, or: Performance Optimization Is a Process
It’s smart to have a vision for what one wishes to achieve for the performance of a site or app. Yet even the soundest approaches to performance visions have their problems, and in them we recognize that performance, or performance optimization, is indeed a process.
Should Designers Code
Arguments for a “no” to a recurring question: Why we may want to give designers all freedom in the world, not to be limited in what they’re trained to do best.
Performance Rule #1: Do What You Need to Do—But Not More
Web Performance has over the age of the Web not only turned into a discipline by itself, but also a complex one at that. While important much less so for revenue but for user experience and accessibility reasons, there’s a particular angle at performance that makes the matter very simple: the pragmatic angle.
How to Configure Lighthouse for Balanced Quality Websites
Google’s Lighthouse is a great tool even though it has some issues. Fortunately, it’s possible to configure Lighthouse to one’s own views on what matters. Here’s the config that I like to use.
A Short Guide to Minimal Web Development
There’s an art and even a bit of magic around simple frontend code. Writing such code comes with a few preconditions: perhaps a firm understanding of core technologies, a lot of practice, public scrutiny, and then some. Thoughts.
Web Development and the GDPR
Who shares or presents code has a special responsibility, because for both the uninitiated and the quality-minded such code should be of a considerable standard. European privacy legislation ups the ante.
37 Theses on CSS and Web Development
CSS Optimization Basics ends with a list of key ideas. From acknowledging that we don’t always write perfectly efficient and maintainable and understandable code to leading by example.

Perhaps my most relevant book: CSS Optimization Basics (2018). Writing CSS is a craft. As craftspeople we strive to write high quality CSS. In CSS Optimization Basics I lay out the, at least some of the most important aspects of such CSS.
