let vs. const
9.1.2020
There are multiple ways to declare variables in JavaScript. We had var, and while that still works like it always has, it is generally said that let and const are replacements to the point we rarely (if ever) need var anymore. This doodle explanation does a pretty good job, if you need...
“All these things are quite easy to do, they just need somebody to sit down and just go through the website”
8.1.2020
I saw a video posted on Twitter from Channel 5 News in the UK (I have no idea what the credibility of them is, it's an ocean away from me) with anchor Claudia Liza asking Glen Turner and Kristina Barrick questions about website accessibility.
Apparently, they often post videos with captions,...
Multi-Thumb Sliders: General Case
8.1.2020
The first part of this two-part series detailed how we can get a two-thumb slider. Now we'll look at a general multi-thumb case, but with a different and better technique for creating the fills in between the thumbs. And finally, we'll dive into the how behind the styling a realistic 3D-looking...
The Auto-Flowing Powers of Grid’s Dense Keyword
8.1.2020
Let's say we're working on the homepage of a news website. You're probably used to seeing some card-based content in a grid layout, right? Here's a classic example, The New York Times:
Yeah, something like that.
There are going to be some cards/elements/boxes/whatever that need to take up more...
The Ultimate Guide to Dark Mode for Email Marketers
7.1.2020
On the regular web (I suppose) we handle "dark mode" with the CSS prefers-color-scheme media query. But, and to nobody's surprise, it's way weirder in the land of HTML email. The weirdness is that across different email clients, they handle the dark mode thing differently, starting with the fact...
Multi-Thumb Sliders: Particular Two-Thumb Case
7.1.2020
This is a concept I first came across a few years back when Lea Verou wrote an article on it. Multi-range sliders have sadly been removed from the spec since, but something else that has happened in the meanwhile is that CSS got better — and so have I, so I recently decided to make my...
Jetpack Slideshow Block
7.1.2020
One of the many (many) useful things that Jetpack does is give you extra-fancy custom blocks in the WordPress block (AKA Gutenberg) editor: a slideshow, business hours, contact info, GIF, Mailchimp, Map, Markdown, Pinterest, Star Rating, Recurring Payments Button, Repeat Visitor, Simple Payments...
How Auto Margins Work in Flexbox
6.1.2020
Robin has covered this before, but I've heard some confusion about it in the past few weeks and saw another person take a stab at explaining it, and I wanted to join the party.
Say you have a flex container with some flex items inside that don't fill the whole area.

Why every website wants you to accept its cookies
6.1.2020
I'm probably in the minority on this, but I've never ever built one of those "This site uses cookies, here's some kind of explanation of why, and please click this OK button to accept that" bars that feels like they are on half of the internet.
Emily Stewart:
Most of us just tediously click “yes”...
How to Stack Elements in CSS
6.1.2020
If you want to create fantastic and unique visual experiences on the web, you will eventually need two elements to overlap or exist in the same place. You may even just need them to be positioned near or next to each other. Let's go over two different ways to accomplish this, one with the position...
Systems, Mistakes, and the Sea
6.1.2020
Our own Robin Rendle:
[...] folks can’t talk about real design systems problems because it will show their company as being dysfunctional and broken in some way. This looks bad for their company and hence looks bad for them. But hiding those mistakes and shortcomings by glossing over everything...
Is “is” Useful?
3.1.2020
God I'm funny.
Anytime we have fairly repetitive selectors that have a common parent, it's probably a place we can use the :is() pseudo-selector.
Holger Bartel demonstrates like this:
section section h1, section article h1, section aside h1, section nav h1,
article section h1, article article...
Gotta Select’em All
3.1.2020
I suspect it is not highly known that CSS can control how text is selected. You can do user-select: none; to prevent some text from being selected. That's probably not terribly good UX in general, but perhaps you use some period (.) characters as decoration or something, I could see preventing...
Microbrowsers are Everywhere
3.1.2020
The word "microbrowser" clearly got my attention. Never heard that before. Colin Bendell defines them as the little parts of other software that do HTTP requests to a URL to generate a preview. Like the little URL preview in iOS messages, WhatsApp, or Slack.
I'm a tiny bit skeptical of the name...

Hats off to Neal Agarwal for some stellar interactive work lately, like The Deep Sea, a vertical scrolling experience to help us understand the depth of the oceans, and The Size of Space, a side-scrolling experience to help us understand the size scale of things in the universe (check out Josh...
How to Build Your Resume on npm
2.1.2020
Just yesterday, Ali Churcher shared a neat way to make a resume using a CSS Grid layout. Let’s build off that a bit by creating a template that we can spin up whenever we want using the command line. The cool thing about that is that you’ll be able to run it with just one command.

Adding Dynamic And Async Functionality To JAMstack Sites
2.1.2020
Jason Lengstorf:
Here’s an incomplete list of things that I’ve repeatedly heard people claim the JAMstack can’t handle that it definitely can:
Load data asynchronously
Handle processing files, such as manipulating images
Read from and write to a database
Handle user authentication and protect...
New Year, New Job? Let’s Make a Grid-Powered Resume!
1.1.2020
Many popular resume designs are making the most of the available page space by laying sections out in a grid shape. Let’s use CSS Grid to create a layout that looks great when printed and at different screen sizes. That way, we can use the resume online and offline, which might come in handy during...
PSA: It’s That Time to Update the Copyright Year on Your Site
1.1.2020
Every year about this time I see articles going around reminding people how to update the copyright on their websites. Usually somewhere in the footer. You know, a line like:
© Copyright 2007-2019 CSS-Tricks
I am very absolutely not a lawyer, but this is how I understand it:
You don't actually...
