The backdrop-filter CSS property

I had never heard of the backdrop-filter property until yesterday, but after a couple of hours messing around with it I’m positive that it’s nothing more than magic. This is because it adds filters (like changing the hue, contrast or blur) of the background of an element without changing the text or other elements inside.

Take this example where I’ve replicated the iOS notification style: see how the background of each of these boxes are blurred but the text isn’t?…

Solved With CSS! Colorizing SVG Backgrounds

CSS is getting increasingly powerful, and with features like CSS grid and custom properties (also known as CSS variables), we’re seeing some really creative solutions emerging. The possibilities are still being explored on what CSS can do to make writing UI’s simpler, and that’s exciting!

Using SVG to Create a Duotone Effect on Images

Creatives everywhere welcomed the 2016 new year with the spark of a colorizing technique popularized by Spotify’s 2015 Year in Music website (here is last year’s) which introduced bold, duotone images to their brand identity.

The Contrast Swap Technique: Improved Image Performance with CSS Filters

With CSS filter effects and blend modes, we can now leverage various techniques for styling images directly in the browser. However, creating aesthetic theming isn’t all that filter effects are good for. You can use filters to indicate hover state, hide passwords, and now—for web performance.

While playing with profiling performance wins of using blend modes for duotone image effects (I’ll write up an article on this soon), I discovered something even more exciting. A major image optimization win! …

Breaking down CSS Box Shadow vs. Drop Shadow

Drop shadows. Web designers have loved them for a long time to the extent that we used to fake them with PNG images before CSS Level 3 formally introduced them to the spec as the box-shadow property. I still reach for drop shadows often in my work because they add a nice texture in some contexts, like working with largely flat designs.

Not too long after box-shadow was introduced, a working draft for CSS Filters surfaced and, with it, a …

Using Filters in Vue.js

Filters are an interesting way to deal with data rendering in Vue but are only useful in a small amount of cases. The first thing to understand about filters is that they aren’t replacements for methods, computed values, or watchers, because filters don’t transform the data, just the output that the user sees. As of Vue 2.0, there are no built-in filters, we need to construct them ourselves.

We can use filters locally or globally, but it’s worth mentioning …
