ColorMe / CSS Color Level 4

Does this look weird?

.element {
  background: color(#eb8fa9 alpha(75%) blackness(20%));

That's the "color function" from a draft spec from the CSS working group. I think it's all about making colors a little easier and more intuitive to work with. Looks awesome to me, as someone who uses Sass color manipulation functions quite a bit.… Read article


High Contrast, A PostCSS Plugin Story*

8-Digit Hex Codes?

Weird right? 4-digit hex codes too. They are a way put alpha transparency information into the hex format for colors. You might be seeing it more all the sudden if you use Chrome, because it dropped in 52, and the DevTools seem to be defaulting to showing alpha transparent colors in this format even if you set it originally using something else.

Firefox supports it too, for the record.… Read article


RGBa Browser Support

This article was originally published on February 2, 2009 and is now being updated to clarify the concept and update the information for modern browsers.

RGBa is a way to declare a color in CSS that includes alpha transparency support. It looks like this:

div {
   background: rgba(200, 54, 54, 0.5); 

This allows us to fill areas with transparent color; the first thee numbers representing the color in RGB values and the fourth representing a transparency value between 0 … Read article
