New business wanted
30 September 2021 @ 10:22 am
Last week Krijn and I decided to cancel performance.now() 2021. Although it was the right decision it leaves me in financially fairly dire straits. So I’m looking for new jobs and/or donations.
Even though the Corona trends in NL look good, and we could probably have brought 350 people together in November, we cannot be certain: there might be a new flare-up. More serious is the fact that it’s very hard to figure out how to apply the Corona checks Dutch government requires, especially for non-EU citizens. We couldn’t figure out how UK and US people should be tested, and for us that was the straw that broke the camel’s back. Cancelling the conference relieved us of a lot of stress.
Still, it also relieved me of a lot of money. This is the fourth conference in a row we cannot run, and I have burned through all my
position: sticky, draft 1
8 September 2021 @ 5:44 pm
I’m writing the position: sticky part of my book, and since I never worked with sticky before I’m not totally sure if what I’m saying is correct.
This is made worse by the fact that there are no very clear tutorials on sticky. That’s partly because it works pretty intuitively in most cases, and partly because the details can be complicated.
So here’s my draft 1 of position: sticky. There will be something wrong with it; please correct me where needed.
The inset properties are top, right, bottom and left. (I already introduced this terminology earlier in the chapter.)
h3,h4,pre {clear: left}
section.scroll-container {
border: 1px solid black;
width: 300px;
height: 250px;
padding: 1em;
overflow: auto;
--text: 'scroll box';
float: left;
clear: left;
margin-right: 0.5em;

Breaking the web forward
12 August 2021 @ 3:19 pm
Safari is holding back the web. It is the new IE, after all. In contrast, Chrome is pushing the web forward so hard that it’s starting to break. Meanwhile web developers do nothing except moan and complain. The only thing left to do is to pick our poison.
blockquote {
font-size: inherit;
font-family: inherit;
}
blockquote p {
font-size: inherit;
font-family: inherit;
}
Safari is the new IE
Recently there was yet another round of “Safari is the new IE” stories. Once Jeremy’s summary and a short discussion cleared my mind I finally figured out that Safari is not IE, and that Safari’s IE-or-not-IE is not the worst problem the web is facing.

Custom properties and @property
21 July 2021 @ 1:18 pm
You’re reading a failed article. I hoped to write about @property and how it is useful for extending CSS inheritance considerably in many different circumstances. Alas, I failed. @property turns out to be very useful for font sizes, but does not even approach the general applicability I hoped for.
Grandparent-inheriting
It all started when I commented on what I thought was an interesting but theoretical idea by Lea Verou: what if elements could inherit the font size of not their parent, but their grandparent? Something like this:
div.grandparent {
/* font-size could be anything */
}
div.parent {
font-size: 0.4em;
}
div.child {
font-size: [inherit from grandparent in some sort of way];
font-size: [yes, you could do 2.5em to restore the grandpar
Let’s talk about money
29 June 2021 @ 11:23 am
Let’s talk about money!
Let’s talk about how hard it is to pay small amounts online to people whose work you like and who could really use a bit of income. Let’s talk about how Coil aims to change that.
Taking a subscription to a website is moderately easy, but the person you want to pay must have enabled them. Besides, do you want to purchase a full subscription in order to read one or two articles per month?
Sending a one-time donation is pretty easy as well, but, again, the site owner must have enabled them. And even then it just gives them ad-hoc amounts that they cannot depend on.
Then there’s Patreon and Kickstarter and similar systems, but Patreon is essentially a subscription service while Kickstarter is essentially a one-time donation service, except that both keep part of the money you donate.
And then there’s ads ... Do we want small content creators to remain dependent o
Inherit, initial, unset, revert
2 June 2021 @ 10:55 am
Today we’re going to take a quick look at a few special CSS keywords you can use on any CSS property: inherit, initial, revert, and unset. Also, we will ask where and when to use them to the greatest effect, and if we need more of those keywords.
The first three were defined in the Cascading Level 3 spec, while revert was added in Cascading Level 4. Despite 4 still being in draft revert is already supported.

The
aspect-ratio
19 May 2021 @ 10:35 am
This week we’ll take a look at the new aspect-ratio declaration and its use. Una Kravets wrote the introductory article, but there are some additional technical points to be made. I also wrote a little fallback that you might use if you need aspect-ratio right now.
At the time of writing aspect-ratio is supported by Chrome 90, by Safari Technology Preview, and by Firefox 88 if you set the aspect-ratio flag in about:config. You need one of these browsers to see the examples below — except for the fallback, which should work in all browsers that support custom properties.
.inner-box {
border: 0;
outline: 1px solid black;
background-size: contain;
background-position: center;
background-repeat: no-repeat;

aspect-ratio and grid
11 May 2021 @ 12:42 pm
I’m currently investigating the new aspect-ratio declaration and plan to write an article about it. However, I got stuck on
aspect ratios in a grid context. Chrome/Safari and Firefox do something different here, and I understand neither approach. So I hope I can get some help.
aspect-ratio is currently supported by Chrome 90, by Firefox 88 with the correct flag enabled, and by Safari Technology Preview. I tested mostly in the first two — for complicated reasons I cannot install STP right now, but a kind Twitter follower sent me a few screenshots. It behaves as Chrome.
First, a general remark. aspect-ratio is intentionally a fairly weak declaration. It gives way if other constraints on boxes make the requested aspect ratio impossible. Take this example:
.my-box {
width: 100px;
height: 50px;
aspect-ratio
Two options for using custom properties
4 May 2021 @ 2:16 pm
Recently I interviewed Stefan Judis for my upcoming book. We discussed CSS custom properties, and something interesting happened.
We had a period of a few minutes where we were talking past one another, because, as it turns out, we have completely opposite ideas about the use of CSS custom properties. I had never considered his approach, and I found it interesting enough to write this quick post.
Option 1
Take several site components, each with their own link and hover/focus colours. We want to use custom properties for those colours. Exactly how do we do that?
Before my discussion with Stefan that wasn’t even a question for me. I would do this:
.component1 {
--linkcolor: red;
--hovercolor: blue;
}
.component2 {
--linkcolor: purple;
--hovercolor: cyan;
}
a {
color: var(--linkcolor);
}
a:hover,a:focus {
color: var(--hovercol
fit-content and fit-content()
29 April 2021 @ 12:28 pm
Today we will look at fit-content and fit-content(), which are special values for width and grid definitions. It’s ... complicated — not as a concept, but in its practical application.
.width {
width: -moz-fit-content;
width: fit-content;
}
.minwidth {
min-width: -moz-fit-content;
min-width: fit-content;
}
.maxwidth {
max-width: -moz-fit-content;
max-width: fit-content;
}
div.radios {
display: grid;
grid-template-columns: 1fr 1fr;
}
div.radios output {
grid-column: span 2;
}
label {
display: block;
}
.flex div {
flex-basis: 30%;
flex-grow: 1;
}
function initBoxes(obj) {
initCheck();
let container = obj.querySelector('.outer-box');
initRadios();
if (container.slider && container.showComputed) {
container.slider.addEventListener('input',container.showComputed,true)
}
function initCheck() {
let check = obj.querySelector('input[type=checkbox]');
Friday night saw Children in Need raise an incredible £46m, which is about 40% of the amount of money still owed by companies linked to Michelle Mone for faulty PPE delivered during the covid pandemic.

The late paedophile Jeffrey Epstein is facing fresh accusations after the House Oversight Committee released a series of illiterate and incoherent emails seemingly written by a child. 
A man has begun World Kindness Day by hurling all manner of abuse at several drivers on his short commute to work this morning.
Putting World Kindness Day on a wet Thursday in November is clearly the work of a spiteful twat, according to everyone today.
The BBC has issued a formal apology to fictional hotelier Basil Fawlty for edits to footage that made him appear to be a bigoted, incompetent, rage-filled, nasty snob.
The White House has today clarified that recently released Epstein emails alleging “Donald Trump knew about the girls” are “clearly referring to a different Donald Trump,” possibly a quiet accountant from Delaware or a plumber with the same name.
Following newly-released email evidence where Jeffrey Epstein suggests Donald Trump spent hours with one of the victims, the White House has today released a two-word statement from Donald Trump simply reading, ‘Oh f**k.’
The past year has been brutal for retailers, with many respected brands closing stores or shutting down completely. Traditional retailers like Sears, Kmart, JCPenny and Macy’s are struggling to find footing and losing customers. It’s not as if this wasn’t expected- Amazon has been disrupting the world of retail the last twenty years by driving online shopping growth and creating record breaking revenue. People call it The Amazon Effect.
But is this Amazon Effect real? Or is it just the natural turnover of poorly performing companies? According to the Census Bureau, retail spending as a whole is up 5% year over year, and up 17% in the last five years. The ACSI also says there is a rise in how people feel about ret

Whether for internal use or for an open-source project, most programmers hate writing technical documentation. Not just dislike, hate. They hate it. And because they hate it, it usually isn't very good. It can be hard to follow and incomplete, which is irritating to experienced devs and causes panic attacks for newbies just trying to learn something. RTFM, or Read the F@$%& Manual, is an expression commonly thrown at people trying to learn some new coding language or technology, but how can they if nobody wants to WriteTFM?
But even if a developer or team wants to create good documentation, it will inevitably fall short because not everyone learns best through reading. Many people are visual learners, and even more learn best through the act of doing.

Did you know that most men own at least one pair of underwear that's over 7 years old? We didn't' and we sort of wish that realization stayed hidden from us, to be honest. MeUndies, a company leading the movement in underwear innovation by providing comfortable everyday basics and a transparent shopping experience, gave us this fact. They recently started using Foundation on their site in an effort to boost their mobile sales, which constitutes most of their traffic and we wanted to share their story.
After 7 years, it was time for MeUndies to change their site's underwear, which is to say their code. See, the MeUndies site was beginning to boom on mobile, but they were losing sales by not optimizing the experience and ease of use for those mobile users. The team began to put their heads together and started exploring solutions.
The explosion of native mobile apps this decade put a spotlight on human centered design. Apple's iPhone and iOS were breakthroughs in part because of the way they used design to mimic humans and appeal to emotion. How good a design looks now plays second fiddle to the way it feels. New terms like 'microinteractions' and 'reactive animations' have been thrust into the designer's vernacular. It's a new era of design, the 'Experience Era.'
While mobile has been killin' it in this area, desktop experiences have still felt cl
Designers, it's time to elevate our game or get off the pot. Yes, I'm telling designers to step up. Because I'm not seeing it happen. What I see now are scared designers afraid to make decisions on behalf of their organizations. Creators and craftsmen struggling to tell other people what works best, and it's putting their own future along with their organization's in jeopardy.
Everyone wants the benefits that come along with authority and influence, but most don't want what inevitably follows: the responsibility of decision making. Making decisions all day requires tremendous amounts of mental energy. Sometimes it's not fun and it can be scary. These feelings, combined with impostor syndrome, put doubt into the heads of
