Inline SVG… Cached

12.4.2019
I wrote that using inline <svg> icons makes for the best icon system. I still think that's true. It's the easiest possible way to drop an icon onto a page. No network request, perfectly styleable. But inlining code has some drawbacks, one of which is that it doesn't take advantage...

IntersectionObserver has made lazy loading a lot easier and more efficient than it used to be, but to do it really right you still gotta remove the src and such, which is cumbersome. It's definitely not as easy as: <img src="celebration.jpg" loading="lazy" alt="..." /> Addy Osmani says...

Revisiting the Rendering Tier

5.4.2019
Have you ever created a well-intentioned, thoughtful design system only to watch it grow into an ever-increasing and scary codebase? I've been working in sort of the opposite direction, inheriting the scary codebase and trying to create a thoughtful system from it. Here's Alex Sanders on the topic...

Decaying Sites

4.4.2019
Websites have a tendency to decay all by themselves. Link rot, they call it. Unpaid domain name registrations. Companies that have gone out of business. Site owners that have lost interest. What's sadder than a 404? Landing on a holding page of a URL that used to exist, but now has fallen into...

KV Storage

1.4.2019
localStorage is... Good! It's an incredibly easy API to use. localStorage.setItem('name', 'Chris'); let name = localStorage.getItem('name'); Bad! Philip Walton explains why: localStorage is a synchronous API that blocks the main thread, and any time you access it you potentially prevent your...

A historical look at lowercase defaultstatus

1.4.2019
Browsers, thank heavens, take backward compatibility seriously. Ancient websites generally work just fine on modern browsers. There is a way higher chance that a website is broken because of problems with hosting, missing or altered assets, or server changes than there is with changes in...

Powers of Two

28.3.2019
Refactoring is one of those words that evokes fear in the eyes of many folks, from developers to product owners and everyone in between. It may as well be a four-letter word in many ways.

Next Genpm

27.3.2019
So many web projects use npm to pull in their dependencies, for both the front end and back. npm install and away it goes, pulling thousands of files into a node_modules folder in our projects to import/require anything.
