SCSS rbga() Function Awesome Sauce.
The rgba function can take a color and an opacity as its arguments. You can plug in a variable(!) as the color, including colors defined using hex! This is excellent for buttons, since this means that you can bot
$blue: #4900ff;
.some_class {
background-color: rgba($blue, 1);
&:hover {
background-color: rgba($blue, .5);
}
}
