combining: enhancing the value of the background-image property

Here is a mixin that I would like to modify:

.a () {background-image: url(one.png);}

I want to create a new class .b which inherits properties from .a, but also includes an additional background image layer, like this:

.b {
    .a;                                 <-- import
    background-image: url(second.png);
}

This code snippet should produce the following CSS output:

.b {
    background-image: url(one.png);
    background-image: url(second.png); /* wins */
}

and not:

.b {
    background-image: url(one.png), url(second.png);
}

This is the desired outcome. Can this be achieved in LESS?

Answer №1

In LESS, you can make this happen with a slight tweak to your approach. To achieve the desired outcome, you'll need to declare the images as variables first:

@background-image-a:url('../images/img-a.png') top left repeat;
@background-image-b:url('../images/img-b.png') top left repeat;

Then, when defining a class or id, incorporate the variables like this:

.someClass {
    background: @background-image-a, @background-image-b;
}
