You must import the foundation as
@import '~foundation-sites/scss/foundation';
Since you already have includePath in your webpack.config
After debugging for a while, I found that the problem is that mix base-all includes a different mesh style by default
@mixin foundation-everything(
$flex: true,
$prototype: false
) {
@if $flex {
$global-flexbox: true !global;
}
@include foundation-global-styles;
@if not $flex {
@include foundation-grid;
}
@else {
@if $xy-grid {
@include foundation-xy-grid-classes;
}
@else {
@include foundation-flex-grid;
}
}
)
