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...
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...
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:

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:

Styling a Web Component
8.1.2019
This confused me for a bit here so I'm writing it out while it's fresh in mind. Just because you're using a web component doesn't mean the styles of it are entirely isolated. You might have content within a web component that is styled normally along with the rest of your website. Like this:

Styling a Select Like It’s 2019
31.12.2018
It's rather heartwarming to know you can style a <select> in a rather cross-browser friendly way that doesn't hurt accessibility. Kudos for documenting this Scott!

Gradient Borders in CSS
28.12.2018
Let's say you need a gradient border around an element. My mind goes like this:
There is no simple obvious CSS API for this.
I'll just make a wrapper element with a linear-gradient background, then an inner element will block out most of that background, except a thin line of padding around...
An Initial Implementation of clip-path: path();
24.12.2018
One thing that has long surprised (and saddened) me is that the clip-path property, as awesome as it is, only takes a few values. The circle() and ellipse() functions are nice, but hiding overflows and rounding with border-radius generally helps there already. Perhaps the most useful value...
Reversing an Easing Curve
17.12.2018
Let’s take a look at a carousel I worked on where items slide in and out of view with CSS animations. To get each item to slide in and out of view nicely I used a cubic-bezier for the animation-timing-function property, instead of using a standard easing keyword.
See the Pen Carousel with reversed...

Hash rate bitcoinu roste raketovou rychlostí. Kurz sice klesá, ale těžaři mu věří
16.7.2018
Ačkoliv cena kryptoměn po loňské mánii pomalu klesá, rozhodně to neznamená, že lidé o tento fenomén ztratili zájem. Tedy – platí to alespoň o klíčovém pilíři celého systému: těžařích.
Jak připomíná web Crypotslate, cena bitcoin use sice od začátku roku propadla o 53 procent,

Building a Complex UI Animation in React, Simply
12.7.2018
Let’s use React, styled-components, and react-flip-toolkit to make our own version of the animated navigation menu on the Stripe homepage. It's an impressive menu with some slick animation effects and the combination of these three tools can make it relatively easy to recreate.
This is...
Custom List Number Styling
18.5.2018
How about a classic CSS trick! This isn't even so tricky anymore, since CSS has counter-increment and counter-reset and such that is perfect for this. I just wanted to make sure you knew how it works and had some easy-to-copy examples at the ready.
Let's say all you wanna do is style the dang...
Responsive Knockout Text With Looping Video
3.5.2018
Here’s an idea! Let’s make an an HTML <video> play inside the shape of some letters. Like "Knockout Text" except instead of an image behind, it’s video. A live demo will explain more clearly:
