Custom Elements v praxi
29.3.2020
Jak se něco dozvědět o nové technologii? Vyzkoušet ji v praxi! Mám za sebou už pár neseriózních pokusů s vlastními HTML značkami a v minulých dnech a týdnech jsem s jejich pomocí přepsal regulérní aplikaci webového klienta pro MPD, nazvaného CYP. Co jsem se při tom naučil a dozvěděl?
Creating a Pencil Effect in SVG
28.3.2020
Scott Turner, who has an entire blog "Exploring procedural generation and display of fantasy maps", gets into why vector graphics seems on these surface why it would be bad for the look of a pencil stroke:

Auto-Growing Inputs & Textareas
25.3.2020
By default, <input> and <textarea> elements don't change size based on the content they contain. In fact, there isn't any simple HTML or CSS way to make them do that. Kinda funny, as that seems like a reasonable use-case. But of course, there are ways, my friend. There are always...
How to Create a “Skip to Content” Link
17.3.2020
Skip links are little internal navigation links that help users move around a page. It’s possible you’ve never actually seen one before because they’re often hidden from view and used as an accessibility enhancement that lets keyboard users and screen readers jump from the top of the page to...
What React Does (and Doesn’t Do)
5.3.2020
With a name as big as React, it's bound to cause some Stream-Crossing Confusion, as I like to call it. How do you center a <div> in React? Dave Ceddia:
React cares exactly zero about styling. Think of it as generating the barebones HTML. React will put elements on the page, but everything...
Listen to your web pages
16.2.2020
A clever idea from Tom Hicks combining MutationObserver (which can "observe" changes to elements like when their attributes, text, or children change) and the Web Audio API for creating sounds. Plop this code into the console on a page where you'd like to listen to essentially any DOM change...
Creating a Details Element That Opens But Never Closes
15.2.2020
The <details> and <summary> elements in HTML are useful for making content toggles for bits of text. By default, you see the <summary> element with a toggle triangle (▶︎) next to it. Click that to expand the rest of the text inside the <details> element.
But...

Toward Responsive Elements
12.2.2020
Hot news from Brian Kardell, regarding what we've been referring to as "container queries", the most hotly requested feature in CSS:
There does seem to be some general agreement on at least one part of what I am going to call instead "Responsive Design for Components" and that is that flipping...
Custom Styling Form Inputs With Modern CSS Features
7.2.2020
It’s entirely possible to build custom checkboxes, radio buttons, and toggle switches these days, while staying semantic and accessible. We don’t even need a single line of JavaScript or extra HTML elements! It’s actually gotten easier lately than it has been in the past. Let’s take a look.
Here’s...
Full-Width Elements By Using Edge-to-Edge Grid
7.2.2020
If you have a limited-width container, say a centered column of text, "breaking out" of that to make a full-width element involves trickery. Perhaps the best trick is the one with left relative positioning and a negative left viewport-based margin. While it has it's caveats (e.g. requiring hidden...
Set Type on a Circle… with offset-path
28.1.2020
Here's some legit CSS trickery from yuanchuan. There is this CSS property offset-path. Once upon a time, it was called motion-path and then it was renamed. I sort of rolled my eyes at the time, because the property is so obviously for animating things along a path. But you don't have to use it...
What’s the Difference Between Width/Height in CSS and Width/Height HTML attributes?
24.1.2020
Some HTML elements accept width and height as attributes. Some do not. For example:
<!-- valid, works, is a good idea --<img width="500" height="400" src="..." alt="..."<iframe width="600" height="400" src="..."</iframe<svg width="20" height="20"</svg<!-- not valid...

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...
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...
A CSS Tribute to SVG
31.12.2019
This demo from Jérémie Patonnier is incredible. Make sure to look at it in Firefox because some Chrome bug apparently prevents the entire thing from working.
The big idea is that the entire demo is one <rect> element. That's it. It is duplicated with <use> elements when needed,...
css.gg
18.12.2019
I'm not sure what to call these icons from Astrit Malsija. The title is "500+ CSS Icons, Customizable, Retina Ready & API" and the URL is "css.gg" but they aren't really named anything.
Anyway, their shtick is:
The 🌎's first icon library designed by code.
The idea is that they don't...
