One of the more frequent questions about jOOQ is how to write a derived table (or a CTE). The jOOQ manual shows a simple example of a derived table: In SQL: In jOOQ: And that’s pretty much it. The question usually arises from the fact that there’s a surprising lack of type safety when working … Continue reading How to...

We’re fans of Custom Elements around here. Their design makes them particularly amenable to lazy loading, which can be a boon for performance. Inspired by a colleague’s experiments, I recently set about writing a simple auto-loader: Whenever a custom element appears in the DOM, we wanna load the corresponding implementation...

It’s a question I hear asked quite often: Is it possible to create shadows from gradients instead of solid colors? There is no specific CSS property that does this (believe me, I’ve looked) and any blog post you find about it is basically a lot of CSS tricks to approximate a gradient. We’ll actually cover some of those...

Every now and then, a one blog post is published and it spurs a reaction or response in others that are, in turn, published as blogs posts, and a theme starts to emerge. That’s what happened this past week and the theme developed around the cost of JavaScript frameworks — a cost that, in this case, reveals just how darn...

We often think of background images as texture or something that provides contrast for legible content — in other words, not really content. If it was content, you’d probably reach for an <img> anyway, accessibility and whatnot. But there are times when the position or scale of a background image might sit somewhere...

Geez, leave it to Patrick Brosset to talk CSS performance in the most approachable and practical way possible. Not that CSS is always what’s gunking up the speed, or even the lowest hanging fruit when it comes to improving performance. But if you’re looking for gains on the CSS side of things, Patrick has a nice way of...

I used to have this boss who loved, loved, loved, loved to emphasize words. This was way back before we used a WYSIWYG editors and I’d have to handcode that crap. <p> I used to have this boss who <em>loved</em>, <strong>loved</strong>, <strong><em>loved</em></strong>,...

I’ve found an interesting question on Twitter, recently. Is there any performance impact of using FILTER in SQL (PostgreSQL, specifically), or is it just syntax sugar for a CASE expression in an aggregate function? As a quick reminder, FILTER is an awesome standard SQL extension to filter out values before aggregating...

Do you know that kind of effect where someone’s head is poking through a circle or hole? The famous Porky Pig animation where he waves goodbye while popping out of a series of red rings is the perfect example, and Kilian Valkhof actually re-created that here on CSS-Tricks a while back. I have a similar idea but tackled...
