Let’s use (X, X, X, X) for talking about specificity

Category Image 052

I was just chatting with Eric Meyer the other day and I remembered an Eric Meyer story from my formative years. I wrote a blog post about CSS specificity, and Eric took the time to point out the misleading nature of it (I remember scurrying to update it). What was so misleading? The way I was portraying specificity as a base-10 number system.

Say you select an element with ul.nav. I insinuated in the post that the specificity of that selector was 0011 (eleven, essentially), which is a number in a base-10 system. So I was saying tags = 0, classes = 10, IDs = 100, and a style attribute = 1000. If specificity was calculated in a base-10 number system like that, a selector like ul.nav.nav.nav.nav.nav.nav.nav.nav.nav.nav.nav (11 class names) would have a specificity of 0111, which would be the same as ul#nav.top. That’s not true. The reality is that it would be (0, 0, 11, 1) vs. (0, 1, 0, 1) with the latter easily winning.

That comma-separated syntax like I just used solves two problems:

  1. It doesn’t insinuate a base-10 number system (or any number system)
  2. It has a distinct and readable look

I like the (X, X, X, X) look. I could see limiting it to (X, X, X) since a style attribute isn’t exactly a selector and usually isn’t talked about in the same kind of conversations. The parens make it more clear to me, but I could also see a X-X-X (dash-separated) syntax that wouldn’t need them, or a (X / X / X) syntax that probably would benefit from the parens.

Selectors Level 3 uses dashes briefly. Level 2 used both dashes and commas in different places.

Anyway, apparently I get the bug to mention this every half-decade or so.

Swipey Image Grids

Category Image 091

I hope people think of SVG as a vector format that is good for drawing things. There is plenty more to know, but here’s one more: SVG is good for composition. You draw things at very specific coordinates in SVG and, while they can scale, they tend to stay put. And while SVG is a vector format, you can place raster images onto it. That’s my favorite part of Cassie’s “Swipey image grids” post. The swipey part is cool, but the composition is even cooler.

<svg viewBox="0 0 100 100">
  <rect x="30" y="0" width="70" height="50" fill="blue"/>
  <rect x="60" y="60" width="40" height="40" fill="green"/>
  <rect x="0" y="30" width="50" height="70" fill="pink"/>

  <image x="30" y="0" width="70" height="50" href="https://place-puppy.com/300x300"/>
  <image x="60" y="60" width="40" height="40" href="https://place-puppy.com/700x300"/>
  <image x="0" y="30" width="50" height="70" href="https://place-puppy.com/800x500"/>
</svg>

You’ll need to check this out in Chrome, Edge or Firefox:

Don’t miss Cassie’s interactive examples explaining preserveAspectRatio. That’s a thing I normally think of on the <svg> itself, but is used to great effect on the <image> elements themselves here. It’s like a more powerful object-fit and object-position.

How to retrieve a device name from IP or MAC on LAN

558fe5180e0e8fc922d31c23ef84d240

In Visual Studio 2015, VB, in Windows 10, I have a small program where I use the arp -a command
to pick up the mac and I/P addresses of connected devices on my lan. From everything I've read (and tried), the answer
somehow comes back to DNS.getHostEntry which throws a No Such Host when fed a cell's I/P and
I understand that, a cell phone is not a host. Does anyone know of the appropriate DNS or other type
command that, fed an I/P or MAC will return the device's name?

Thank you.

Jenny B Kowalski’s A-Z (and a-z) as Variable Letterforms

Category Image 052

Jenny B Kowalski has been posting a-letter-a-day on Instagram exploring multi-axis variable/responsive letterforms. They are very clever in that one of the axes controls an uppercase-to-lowercase conversion, literally morphing the shape of the letters from an uppercase version to a lowercase version. The other axis is a stroke weight, which also dramatically changes the feel of the letters.

Here’s Q, one of my favorites:

She’s using p5.js, but I don’t see any reason these couldn’t be made into a variable font with custom axes.

OK here’s one more. I find the I/i very clever:
