Issue with duplicate selectors not being merged in SASS partials

Is there a way for SASS to combine duplicate CSS selectors from multiple files into a single output file?

In my current setup, I have the same CSS selector present in separate SASS partials files that are all included in a master file. For example:

File1:

.mySelector { color: #ffffff; }

File2:

.mySelector { line-height: 1; }

Master file:

@import 'partials/File1';
@import 'partials/File2';

Instead of combining these duplicate selectors into one in the final CSS output file, SASS creates two separate instances. Is there a setting or workaround that can help merge identical selectors during compilation?

Answer №1

It is important to understand that the order of rules in a CSS file has significant impact on the styling of elements. Consider the example below:

.foo {
  color: 'red';
}
.bar {
  color: 'blue';
  line-height: 1;
}
.foo {
  line-height: 2;
}

Merging the two rules for the .foo selector would lead to incorrect behavior, as it would not preserve the intended styling for elements with both foo and bar classes.

Answer №2

From what I recall, SASS does not have a feature for combining identical selectors. It may be necessary to refactor your code in this case.

Wouldn't it make more sense for changes to be made in just one location within a file? Having modifications spread across multiple spots could complicate things, especially for someone else trying to navigate and understand the code.
