Almanac

border-spacing

The border-spacing property in CSS controls how far apart cells are in a <table></table> element (or an element that is made to be table-like via display: table;).

It takes any of the lengths of CSS.

Notably, it only has any effect at all if the table is using the default border-collapse: separate; and has no effect at all when border-collapse: collapse; is set.… Read article

Bounce Element Around Viewport in CSS

Let's say you were gonna bounce an element all around a screen, sorta like an old school screensaver or Pong or something.

You'd probably be tracking the X location of the element, increasing or decreasing it in a time loop and — when the element reached the maximum or minimum value — it would reverse direction. Then do that same thing with the Y location and you've got the effect we're after. Simple enough with some JavaScript and math. … Read article

Can you view print stylesheets applied directly in the browser?

Yep.

Let's take a look at how to do it in different browsers. Although note the date of this blog post. This stuff tends to change over time, so if anything here is wrong, let us know and we can update it.… Read article

Staggered CSS Transitions

Let's say you wanted to move an element on :hover for a fun visual effect.

@media (hover: hover) {
  .list--item {
    transition: 0.1s;
    transform: translateY(10px);
  }
  .list--item:hover,
  .list--item:focus {
    transform: translateY(0);
  }
}

Cool cool. But what if you had several list items, and you wanted them all to move on hover, but each one offset with staggered timing?… Read article

The Differing Perspectives on CSS-in-JS

Some people outright hate the idea of CSS-in-JS. Just that name is offensive. Hard no. Styling doesn't belong in JavaScript, it belongs in CSS, a thing that already exists and that browsers are optimized to use. Separation of concerns. Anything else is a laughable misstep, a sign of not learning from the mistakes of the past (like the <font></font> tag and such.)

Some people outright love the idea of CSS-in-JS. The co-location of templates and functionality, à la most … Read article

Site Monetization with Coil (and Removing Ads for Supporters)

I've tried a handful of websites based on "tip with micropayments" in the past. They come and go. That's fine. From a publisher perspective, it's low-commitment. I've never earned a ton, but it was typically enough to be worth it.

Now Bruce has me trying Coil. It's compelling to me for a couple reasons:

  • The goal is to make it based on an actual web standard(!)
  • Coil is nicely designed. It's the service that readers actually subscribe to

Moving Text on a Curved Path

There was a fun article in The New York Times the other day describing the fancy way Elizabeth Warren and her staff let people take a selfie with Warren. But... the pictures aren't actually selfies because they are taken by someone else. The article has this hilarious line of text that wiggles by on a curved line as you scroll down the page.

Let's look at how they did it.… Read article

#174: Using Local Overrides in DevTools

There is a feature of Chrome DevTools that lets you:

  1. See the code of any given resource the current web page is using (like CSS and JavaScript).
  2. "Pretty Print" it (format it for readability)
  3. Save it to disk
  4. Use that saved version to override the live version, even on page refresh.

That last one is pretty awesome. If you're debugging a problem that only seems to happen on the live website, it gives you a debugging tool that will allow … Read article

#173: Ooooops I guess we’re full-stack developers now.

And by "we're", I mean us, front-end developers ;)

Here's the website that goes with this talk.

This is a talk I put together where I postulate that, over time, the breadth of what front-end developers are able to do and are being asked to do has widened to the point that it's become full-stack development. Not that we've replaced back-end developers, because they are as important as ever too, it's just there is more overlap and more possibility.

Also, … Read article

Quick Gulp Cache Busting

You should for sure be setting far-out cache headers on your assets like CSS and JavaScript (and images and fonts and whatever else). That tells the browser "hang on to this file basically forever." That way, when navigating from page to page on a site — or revisiting it, or refreshing the page — the browser doesn't have to download it again which produces way faster page loads. It's massively important for web performance, so do it!

But how do … Read article
