mix-blend-mode: multiply

By  on  

One of my favorite interview questions is "how do you stay current on emerging front-end techniques and APIs?"  I always get the standard "blogs" and "RSS" answers but rarely do I ever hear "from gurus on Twitter."  I find that strange because I learn loads from Twitter, especially when it comes to CSS, because a tiny snippet can do something really neat.

I had heard CSS mix-blend-mode was something awesome but this blew my mind:

Essentially, using mix-blend-mode: multiply; on an image with white background would turn that white into a level of opacity as though the image were a .png with opacity.  Whoa!  I created a demo here:

What an awesome bit of CSS!  Thanks to Wes Bos for the heads up on this nifty CSS feature!

    Create Namespaced Classes with MooTools

    MooTools has always gotten a bit of grief for not inherently using and standardizing namespaced-based JavaScript classes like the Dojo Toolkit does.  Many developers create their classes as globals which is generally frowned up.  I mostly disagree with that stance, but each to their own.  In any event...

    CSS vs. JS Animation: Which is Faster?

    How is it possible that JavaScript-based animation has secretly always been as fast — or faster — than CSS transitions?

    Form Element AJAX Spinner Attachment Using MooTools

    One event that's always been lacking within the document is a signal for when the user is looking at a given tab, or another tab. When does the user switch off our site to look at something else? When do they come back?

    you know why twitter is bad source? cause it’s just like any channel throwing everything in single place: you’ll miss many important things, twitter is meant for things that are important only in a given moment, not for sharing knowledge

    Holy moly, this is amazing. Didn’t know that’s possible at all even if I always wished for this feature.
    Well, I learn stuff like that from sites like this. Thanks! :)

    I wanted to use this on a recent website I made to save the client uploading heavy PNGs. But it doesn’t work in Edge or IE so had to remove it :(

      I usually save between 50-80% of filesize by using http://tinypng.com to optimize my pngs. You should give it a go, it works wonders.

Wrap your code in <pre class="{language}"></pre> tags, link to a GitHub gist, JSFiddle fiddle, or CodePen pen to embed!
