Autoprefixer 8.6 brings gap property support and two values support for grid-gap/gap.

Grid Gap

CSSWG renamed grid-gap property to gap.

@yepninja added gap support with 2 values support.

Grid layout code bellow will work even in IE if you pass grid: true option to Autoprefixer:

.main {
    gap: 10px 20px;
    grid-template-columns: 1fr 1fr 1fr;
    grid-template-areas: "head head head"
                         "nav main main"
                         "nav foot foot";
}
