I have two scss files

fileA:

body {
   background-color: pink;
}

fileB:

body {
   background-color: green;
}

these two files are importet in my JS file:

import './fileA.scss';
import './fileB.scss'

My expectation is that fileB overwrites the background deklaration from fileA to green.
But on my bundled output file I get:

body{background-color:pink;background-color:green}

So my question is: Is there a possibility to overwrite a previos declaration in Sass?
For my rollup config i use:

• rollup
• rollup-plugin-styler
• sass
