Web Development
One-Dimensional Website Optimization Considered Harmful
There are many website optimization vectors—SEO, performance, accessibility, &c.—, but optimizing on only one dimension may not only be expensive, but also counter-productive. On optimizing optimizations.
Website Optimization Measures, Part XIV
About link relationships, Twitterbot, dark mode, tags, addresses, social markup, color-scheme
, and—FLoC.
Minimal Social Markup
Every website and app these days relies on so-called “social markup,” metadata for a richer and prettier display in social media and messaging tools. On the absolute minimum you may need.
Thoughts on an Accessibility “Get Well” Plan
Have you wondered how to anchor accessibility in an engineering team, one that isn’t yet producing accessible sites or apps? Some options to start with, for further refinement and discussion.
The Machine-Illustrated Life of a Frontend Developer
You may know DALL·E, what you can do with it, what others do with it, and… be intrigued by it, too. And you may wonder, how would AI depict frontend developers?
HTML Concepts: Focusable Areas
When you hear “focusable area,” what comes to your mind? Anchors and form elements that receive focus when being “tabbed through,” i.e., that are highlighted and that can be interacted with? That’s not a bad description!—but also not a complete one.
Write HTML, the HTML Way (Not the XHTML Way)
You may not use XHTML (anymore), but when you write HTML, you may be more influenced by XHTML than you think. You are very likely writing HTML, the XHTML way.
2 Approaches to Accessibility on the Web
One can distinguish two approaches to accessibility on the Web: to produce accessible websites and apps (active accessibility), and to produce accessible-making software (passive accessibility). On how largely using one approach would stand in the way of a greater vision for web accessibility.
The CSS Art Paradox
The fanciest CSS, standing on the shoulders of bloated HTML.
3 Books to Become a Better Developer
When a frontend developer chooses A Philosophy of Software Design, The Pragmatic Programmer, and Clean Code.
HTML Concepts: Commands and Facets
On what you think they are, and something that what you think they are has.
What Makes You a Professional Web Developer
On a starting point that involves committing to high standards (including validating, and exercising control over oneself), acting ethically, practicing, learning, taking care of oneself, and taking care of others.
Website Optimization Measures, Part XIII
Lessons from running multiple websites, this time covering SVGs, HTML optimization, auto-completion, semantics tricks, code styling, favicon markup, and social images. Happy Saturday.
25 Web Development Terms You’ve Never Heard Of
__qem
s, cyclomatic complexity, homogenous migrations, NUIs, OOPIFs, and everything the web and software developer needs.
On the Difficulty of Counting the Number of HTML Elements
How many HTML elements are there? What looks like a fairly simple question, isn’t one, because there isn’t one number of HTML elements.
Reduce the Pressure on Young and Inexperienced Developers
Lower the expectations on young and inexperienced developers, and raise the expectations on their mentoring and coaching: on running gags, unrealistic expectations, and healthier hiring.
HTML Concepts: Form Owners
Today in “HTML Concepts”: form owners. It’s not what you are when you put a form on a page. What are form owners? In essence, form elements that so-called form-associated elements are tied to.
Web Frameworks, Coding Guidelines, Quality Control, and the Craft of Web Development
“Good frameworks aim to be tailored, usable, and extensible”? “Coding guidelines must be communicated, enforced, and reviewed”? “No website should go without a plan for quality control”?
The 6 Ways of Writing HTML (and Their Combinations)
There are 6 general ways of writing HTML: unsystematic, valid, semantic, accessible, required-only, and hyper-optimized. These types make for 19 combinations—the ways we write HTML.
HTML Concepts: Common Idioms
Welcome to another brief post in the “HTML Concepts” series. Today we’re going to look at common idioms: popular design patterns for which HTML doesn’t have dedicated elements, but makes suggestions.
Making the Web Developer’s Pilgrimage
Have you read the HTML specification? Have you marked highlights, taken notes, and reviewed what you learned? Have you reported issues and made suggestions to the HTML working group, giving back and improving the standard? On our field’s “pilgrimage.”
Declaring Page Language—and Declaring Changes in Language
Popular screen readers don’t seem to pick up changes in language automatically. We may need a push on screen readers to improve detection of changes in language, and a shift of attention from declaration of page language to marking up changes in language.
Comparing Page Language Declaration Setups in Screen Readers
One best practice in web development is to declare the document language via the lang
attribute, on the html
start tag. That is useful, but also not the only option. How well are different setups supported in screen readers? A few data points.
Not Releasing Late on Fridays, a Matter of Courtesy
Why don’t we, in engineering departments, prefer not to release late on Fridays—or late on others days? Occasionally, developers and stakeholders believe that’s because of a lack of confidence in our code and our systems. The true reason is not that:—
HTML Concepts: Indicators for Layout Tables
You use tables for data, and therefore not for layout purposes (as was popular in the past). But how would you recognize a layout table? That’s what we’re looking at today in “HTML Concepts.”
