The Serif Tax

Fonts are vector. Vector art with more points makes for larger files than vector art with fewer points. Custom fonts are downloaded. So, fonts with less points in their vector art are smaller. That’s the theory anyway. Shall we see if there is any merit to it? Open Sans (top) and Garamond (bottom) Let’s take two fonts off of Google Fonts: Open Sans and EB Garamond. The number of points isn’t a dramatic difference, but the seriffed Garamond does have more of them, particularly in looking at the serif areas. It’s not just serifs, but any complication. Consider Bleeding...

Native Lazy Loading

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: Addy Osmani says it’s coming in Chrome 75: The loading attribute allows a browser to defer loading offscreen images and iframes until users scroll near them. loading supports three values: lazy: is a good candidate for lazy loading. eager: is not a good candidate for lazy loading. Load right away. auto: browser will determine whether or not to lazily load....

Undefined: The Third Boolean Value

I wanted to implement a notification message in one of my projects, similar to what you’d see in Google Docs while a document is saving. In other words, a message shows up indicating that the document is saving every time a change is made. Then, once the changes are saved, the message becomes: “All changes saved in Drive.” Let’s take a look at how we might do that using a boolean value, but actually covering three possible states. This definitely isn’t the only way to do this, and frankly, I’m not even sure if it’s the best way. Either...

Decaying Sites

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 the hands of some domain hoarder after it expired, hoping someone will pay a premium to get it back. That stuff is no fun. But what about sites that are totally still around, just old? What kind of fun things could we do to indicate oldness...

Fixed Headers, On-Page Links, and Overlapping Content, Oh My!

Let’s take a basic on-page link: Section Two When clicked, the browser will scroll itself to the element with that ID: . A browser feature as old as browsers themselves, just about. But as soon as position: fixed; came into play, it became a bit of an issue. The browser will still jump to bring the newly targeted element into view, but that element may be obscured by a fixed position element, which is pretty bad UX. I called this “headbutting the browswer window” nearly 10 years ago, and went over some possible solutions. Nicolas Gallager documented five different...
