Split grid & containers (#29146) 2020-02-03 20:02:53 +00:00			`// Container mixins`

Match container gutters with row gutters - Replaces make-container mixin's padding-x param with gutter to match naming - Changes value of container padding variable to match grid gutter width variable - Uses local CSS variable for container padding Fixes #31642 2020-09-14 16:58:48 +00:00			`@mixin make-container($gutter: $container-padding-x) {`
Always set the CSS variables for gutters in containers (#34644) We already do this in rows, so to best support our containers, we need to do it at the container level as well. Fixes #32658, fixes #34614, closes #32658. Co-authored-by: XhmikosR <xhmikosr@gmail.com> 2021-11-01 06:39:48 +00:00			`--#{$variable-prefix}gutter-x: #{$gutter};`
