Start by setting a variable to the colors you want:
$rainbow: red orange yellow green blue indigo violet;You could set individual variables for each color as well. You would still pass them all as a single argument, or join them into a single variable before passing, as you see fit.
Here’s the function:
// Returns a striped gradient for use anywhere gradients are accepted.
// - $position: the starting position or angle of the gradient.
// - $colors: a list of all the colors to be used.
@function stripes($position, $colors) {
$colors: if(type-of($colors) != 'list', compact($colors), $colors);
$gradient: compact();
$width: 100% / length($colors);
@for $i from 1 through length($colors) {
$pop: nth($colors,$i);
$new: $pop ($width * ($i - 1)), $pop ($width * $i);
$gradient: join($gradient, $new, comma);
}
@return linear-gradient($position, $gradient);
}And how to use it:
.rainbow {
@include background-image(stripes(left, $rainbow));
}Jina has posted a demo and explanation on CodePen.
(The real lesson here is that all the colors of the rainbow are acceptable CSS color keywords. Go forth and queer the web.)
There are several proposals, but one major road block
We’re trying to make progress on shorthand syntax for CSS logical properties. But the path forward depends on where we hope to be a decade from now.
Can we get this process unstuck?
The CSS Working Group recently resolved to add a size shorthand for setting both the width and height of an element. Many people asked about using it to set the ‘logical’ inline-size and block-size properties instead. But ‘logical shorthands’ have been stalled in the working group for years. Can we…
It’s not just a shorthand for anchor()
position-area might be my favorite part of the CSS Anchor Positioning spec, with a ton of features packed in to make things just… work. But there’s no magic here, just a few key parts that work well.
