Musings on HTTP/2 and Bundling

HTTP/2 has been one of my areas of interest. In fact, I've written a few articles about it just in the last year. In one of those articles I made this unchecked assertion:

If the user is on HTTP/2: You'll serve more and smaller assets. You’ll avoid stuff like image sprites, inlined CSS, and scripts, and concatenated style sheets and scripts.

I wasn't the only one to say this, though, in all fairness to Rachel, she qualifies her assertion with caveats in her article. To be fair, it's not bad advice in theory. HTTP/2's multiplexing ability gives us leeway to avoid bundling without suffering the ill effects of head-of-line blocking (something we're painfully familiar with in HTTP/1 environments). Unraveling some of these HTTP/1-specific optimizations can make development easier, too. In a time when web development seems more complicated than ever, who wouldn't appreciate a little more simplicity?


Using WebP Images

We've all been there before: You're browsing a website that has a ton of huge images of delicious food, or maybe that new gadget you've been eyeballing. These images tug at your senses, and for content authors, they're essential in moving people to do things.

Except that these images are downright huge. Like really huge. On a doddering mobile connection, you can even see these images unfurl before you like a descending window shade. You're suddenly reminded of the bad old days of dial-up.

This is a problem, because images represent a significant portion of what's downloaded on a typical website, and for good reason. Images are expressive tools, and they have the ability to speak more than copy can. The challenge is in walking the tightrope between visually rich content, and the speedy delivery of it.

The solution to this dilemma is not one dimensional. (more…)

`font-display` for the Masses

If you're a regular reader here at CSS-Tricks, chances are good that you're familiar with using web fonts. You may even know a few useful tricks to control how fonts load, but have you used the CSS font-display property?

The font-display property in CSS is newly available in Blink-based browser. It gives us the same power found in browser features such as the Font Loading API and third party scripts such as Bram Stein's Font Face Observer. The key difference, though, is that this capability is also now a CSS feature.
