Sass Flexbox Mixins

In my day-to-day web development work at FHOKE, I write a lot CSS (more specifically Sass). When we started implementing flexbox across various client sites I found it incredibly time consuming having to Google all the variations of each flexbox property to support older browsers (think -webkit- and -ms-).

You might not need the below mixins if you don’t support certain browsers, or version of browsers, however when building client sites we like to make them work across as many devices and browsers as possible, within reason of course, so the following mixins are tremendously helpful.

The below are simply a bunch of mixins I created to save me time (and I can testify, using the below saves me a lot of time!).

@mixin flex($properties) {
    @if $properties == 'flex' {
        display: -ms-flexbox;
        display: -webkit-flex;
        display: flex;
    } @else if $properties == 'inline-flex' {
        display: -ms-inline-flexbox;
        display: -webkit-inline-flex;
        display: inline-flex;
    }
}

@mixin flex_direction($properties) {
    -webkit-flex-direction: $properties;
    -ms-flex-direction: $properties;
    flex-direction: $properties;
}

@mixin flex_wrap($properties) {
    @if $properties == 'nowrap' {
        -webkit-flex-wrap: nowrap;
        -ms-flex-wrap: nowrap;
        flex-wrap: nowrap;
    } @else if $properties == 'wrap' {
        -webkit-flex-wrap: wrap;
        -ms-flex-wrap: wrap;
        flex-wrap: wrap;
    } @else if $properties == 'wrap-reverse' {
        -webkit-flex-wrap: wrap-reverse;
        -ms-flex-wrap: wrap-reverse;
        flex-wrap: wrap-reverse;
    }
}

@mixin flex_justify($properties) {
    @if $properties == 'flex-start' {
        -webkit-justify-content: flex-start;

        justify-content: flex-start;
    } @else if $properties == 'flex-end' {
        -webkit-justify-content: flex-end;
        -ms-flex-pack: end;
        justify-content: flex-end;
    } @else if $properties == 'center' {
