A web developer and a graphic designer walk into a studio.
Conversation with a friend who works in a web design studio. A print designer decided to switch to web design. - /me "Great! A print designer, an unchained creative coming to the web!" My friend was tasked with helping her out, teaching, supervising. I expected to learn how he'd teach responsive web design, animations, perfromance - /me How's it going?Quiz!
A pop-quiz is a terrible way to get attention. But our school teachers used it with great results. Let's give it a try.- Ancient text

Espresso is coffee brewed by forcing a small amount of nearly boiling water under pressure through finely ground coffee beans. Espresso is generally thicker than coffee brewed by other methods, has a higher concentration of suspended and dissolved solids, and has crema on top (a foam with a creamy consistency).
Tamping down the coffee promotes the water's even penetration of the grounds. This process produces an almost syrupy beverage by extracting both solid and dissolved components. The "crema" is produced by emulsifying the oils in the ground coffee into a colloid, which does not occur in other brewing methods.
.element {

shape-outside: url(image.png);
shape-image-threshold: 0.5;
}
Naive, using img with transparent bg, expecting text to fill the gaps.
Disappointed to get square shape around img.

Fingerprint login on phones? I don't know about you, but that freaks me out. I don't want a thief running off with my phone and a finger. Phones are relatively easy to come by; replacement body parts, not so much.
Plus, I like all of my fingers. I've had them for a long time and I got used to them being there. I don't have a favorite one, they're all useful.
Can you imagine the trouble of tacking on a different finger? I mean, where do you even go to get replacement fingers?

The octopus is a very intelliget sea creature. Most of its neurons are not loctated in its head, like with other animals, but in its arms. You could say that each of its eight arms has a mind of its own. In fact, when threatened, some ocotopi ("octopuses" sounds nicer), can break off one of their arms, which will squiggle around and confuse the predator. That would confuse the hell out of me. The octopus does not have a skeleton. Its body is mostly water and soft cartilage. The only solid part is its bird beek-like mouth. This means that the octopus can squeeze through anything large enough to fit its mouth.
.element{
shape-outside: polygon(111px 239px, 23px 222px, 4px 175px ...)
