This article is going to take you, step by step, through the implementation with the least amount of code I could come up with. So, let’s jump right into it!… Read article “Simple Swipe with Vanilla JavaScript”

Scooped Corners in 2018

When I saw Chris' article on notched boxes, I remembered that I got a challenge a while ago to CSS a design like it, but with rounded, scooped corners instead. So, let's see how we can do it that way instead and expand it to multiple corners while being mindful of browser support.

What Houdini Means for Animating Transforms

I’ve been playing with CSS transforms for over five years and one thing that has always bugged me was that I couldn’t animate the components of a transform chain individually. This article is going to explain the problem, the old workaround, the new magic Houdini solution and, finally, will offer you a feast of eye candy through better looking examples than those used to illustrate concepts.… Read article “What Houdini Means for Animating Transforms”

Using Conic Gradients and CSS Variables to Create a Doughnut Chart Output for a Range Input

I recently came across this Pen and my first thought was that it could all be done with just three elements: a wrapper, a range input and an output. On the CSS side, this involves using a conic-gradient() with a stop set to a CSS variable.… Read article “Using Conic Gradients and CSS Variables to Create a Doughnut Chart Output for a Range Input”

A Sliding Nightmare: Understanding the Range Input

You may have already seen a bunch of tutorials on how to style the range input. While this is another article on that topic, it’s not about how to get any specific visual result. Instead, it dives into browser inconsistencies, detailing what each does to display that slider on the screen. Understanding this is important because it helps us have a clear idea about whether we can make our slider look and behave consistently across browsers and which styles are … Read article “A Sliding Nightmare: Understanding the Range Input”

Creating a Star to Heart Animation with SVG and Vanilla JavaScript

In my previous article, I’ve shown how to smoothly transition from one state to another using vanilla JavaScript. Make sure you check that one out first because I’ll be referencing some things I explained there in a lot of detail, like demos given as examples, formulas for various timing functions or how not to reverse the timing function when going back from the final state of a transition to the initial one.… Read article “Creating a Star to Heart Animation with SVG and Vanilla JavaScript”

Emulating CSS Timing Functions with JavaScript

CSS animations and transitions are great! However, while recently toying with an idea, I got really frustrated with the fact that gradients are only animatable in Edge (and IE 10+). Yes, we can do all sorts of tricks with background-position, background-size, background-blend-mode or even opacity and transform on a pseudo-element/ child, but sometimes these are just not enough. Not to mention that we run into similar problems when wanting to animate SVG attributes without a CSS correspondent.

How to be evil (but please don’t!) – the modals & overlays edition

We’ve all been there. Landed on a website only to be slapped with a modal that looked something like the one below:

Hello darkness, my old friend.

For me that triggers a knee-jerk reaction: curse for giving them a pageview, close the tab, and never return. But there’s also that off case when we might actually try to get to the info behind that modal. … Read article “How to be evil (but please don’t!) – the modals & overlays edition”

Glue Cross-Browser Responsive Irregular Images with Sticky Tape

I recently came across this Atlas of Makers by Vasilis van Gemert. Its fun and quirky appearance made me look under the hood and it was certainly worth it! What I discovered is that it was actually built making use of really cool features that so many articles and talks have been written about over the past few years, but somehow don’t get used that much in the wild – the likes of CSS Grid, custom properties, blend modes, … Read article “Glue Cross-Browser Responsive Irregular Images with Sticky Tape”
