10 Days of React Challenges (Beginner): Loop Over and Display Data with JSX
10.5.2019
Data comes in all shapes and sizes. In JavaScript, an array is how we hold sets of data. For the majority of our site content, we use an array of objects.

10 Days of React Challenges (Beginner): Display Simple Data with JSX
10.5.2019
One of the building blocks of React is the ability to use HTML elements when developing components.
JSX allows us to write simple markup in HT
A responsive grid layout with no media queries
9.5.2019
Andy Bell made a really cool demo that shows us how to create a responsive grid layout without any media queries at all. It happens to look like this when you change the size of the browser window:
I think this is a wonderful layout technique that’s just 6 lines (!) of CSS.
.auto-grid...
Getting To Know The MutationObserver API
8.5.2019
MutationObserver watches the DOM, specifically the places you tell it to, like:
document.querySelector('#watch-this');
...and it can tell you (trigger a callback) when stuff happens — like when a child is added, removed, changed, or a number of other things.
I used it just the other day...
Inclusively Hidden
19.4.2019
Scott O'Hara recently published "Inclusively Hidden," a nice walkthrough of the different ways to hide things on the web. Nothing is ever cut and dry when it comes to the web! What complicates this is that hidden begs the question: hidden for whom? Different answers to that have different...
Příští Apple Watch by mohly mít displeje z Japonska
17.4.2019
Apple postupně přechází na OLED panely a krom iPhonů jimi vybavuje i své chytré hodinky. Watch mají dosud displeje výhradně z produkce LG, ovšem koncem roku by se k této jihokorejské společnosti mohla přidat značka Japan Display, která nedávno ohlásila vstup zahraničních investorů.Další články...
Simulating Mouse Movement
15.4.2019
If you've ever had to display an interactive animation during a live talk or a class, then you may know that it's not always easy to interact with your slides and while talking.
This happened to me when I needed to show this particles demo to my students. I didn't want to have to stay next to...
Creating a Custom Element from Scratch
20.3.2019
In the last article, we got our hands dirty with Web Components by creating an HTML template that is in the document but not rendered until we need it.
Next up, we’re going to continue our quest to create a custom element version of the dialog component below which currently only uses...
The Dark Side of the Grid
10.3.2019
Manuel Matuzovic makes the point that in order to use CSS grid in some fairly simple markup scenarios, we might be tempted to flatten our HTML to make sure all the elements we need to can participate on the grid. What we need is subgrid and non-buggy display: contents;, so I'd like to think in...
Should I Use Source Maps in Production?
1.3.2019
It's a valid question. A "source map" is a special file that connects a minified/uglified version of an asset (CSS or JavaScript) to the original authored version. Say you've got a filed called _header.scss that gets imported into global.scss which is compiled to global.css. That final CSS file...
Control Icons with Font Size
27.2.2019
Here’s a nifty trick from Andy Bell that now seems a little obvious in hindsight: if you set an SVG to have a width and height of 1em then you can change the size of it with the font-size property.
Try and change the font-size on the body element below to see the icon scale with the text:

Where Do You Nest Your Sass Breakpoints?
11.2.2019
I love nesting my @media query breakpoints. It's perhaps the most important feature of Sass to me. Maybe I pick a method and do it like this:
.element {
display: grid;
grid-template-columns: 100px 1fr;
@include breakpoint(baby-bear) {
display: block;
}
}
That's straightforward enough....
Slide an Image to Reveal Text with CSS Animations
29.1.2019
I want to take a closer look at the CSS animation property and walk through an effect that I used on my own portfolio website: making text appear from behind a moving object. Here’s an isolated example if you’d like to see the final product.
Here’s what we're going to work with:

Amazing User Agent API with userstack
17.1.2019
We do our best to design and code websites so that they look and perform the way they should regardless of device or browser, but the truth is we sometimes we need to code for specific device, browser, or crawler. Whether it’s a quick hack or a simply wanting to display different content...
VESA uvedla nový standard monitorů: Display HDR s opravdovou černou [CES]
7.1.2019
Organizace VESA připravila nový standard DisplayHDR True Black, který je rozšířením starajícího DisplayHDR a jehož úkolem je značně vylepšit podání černé barvy u nových zobrazovacích panelů.
U tohoto nového standardu jde o to, jak nízký jas dokáže obrazovka zobrazit pro co nejlepší poddání černé
Fighting FOIT and FOUT Together
19.12.2018
Lots from Divya with the setup:
There are 2 kinds of problems that can arise when using webfonts; Flash of invisible text (FOIT) and Flash of Unstyled Text (FOUT) ... If we were to compare them, FOUT is of course the lesser of the two evils
If you wanna fight FOIT, the easiest tool is...
Google Fonts and font-display
19.12.2018
The font-display descriptor in @font-face blocks is really great. It goes a long way, all by itself, for improving the perceived performance of web font loading. Loading web fonts is tricky stuff and having a tool like this that works as well as it does is a big deal for the web.
It's such a...
A CSS Venn Diagram
17.12.2018
This is pretty wild: Adrian Roselli has made a series of rather complex Venn diagrams using nothing but CSS. With a combination of the Firefox dev inspector, plus a mixture of CSS Grid and the shape-outside property, it’s possible to do this and without a ton of hacks, too.
I also think it’s super...
Stuff you can do with CSS pointer events
27.7.2018
Martijn Cuppens (the same fella with the very weird div!) has some more irresistible CSS trickery. Three of the examples are about making a child element trigger an event on a parent element (almost like the magic that is :focus-within).
Here's how I reasoned it out to myself:
You know how if...
Did you know that style and script tags can be set to display: block?
25.7.2018
The other night, Amit Patel mentioned that you can set script tags in HTML to display: block with CSS and then edit that code inline with the contentEditable attribute. This means that you can then see it all update live in the browser as you type. Shortly after, Marius Gundersen replied that...
