CSS Grid System - Sass

HI, I want to make a grid system so e.g. when i write md or full-md-less or such, my current grid will change.

So right now, the collumns are all 100% width on mobile, and if they pass mobile, they are as much columns, as i set, so tablet is 3 say, and i need to put to be desktop 4, but they wont, since there is only one value.

What would be a good way to do this? theres my css

// ==========================================================================
// Grid Container
// ==========================================================================

.grid {
  content: "";
  display: table;
  clear: both;
  float: none;
  width: 100%;

  // Make nested grid 100%
  [class*="grid__col--"] > & {
    width: 100%; 
  }

  // Set a max-width for grid container
  @media (min-width: 1100px) {
    max-width: $g-cont-max-w;
  }
}

// ==========================================================================
// Grid Columns
// ==========================================================================

// Calculate grid columns

@media (min-width: 769px) {
  @for $i from 1 through $g-col-count {
    $context: g-context($g-col-width, $g-col-count ,$g-gutter-width) !global;  
    $target: ($g-col-width * $i) + ($g-gutter-width * ($i - 1));

    // Generate column modifier classes
    .grid__col--#{$i} {
      width: percentage($target / $context);
    }
  }
}

// Column styles

[class^="grid__col--"] {
  @media (min-width: 1px) and (max-width: 768px) {
    margin-top: em(12px);
    margin-bottom: em(12px);
  }
  @media (min-width: 769px) {
    @include doubly(percentage($g-gutter-width / $context));    
    float: left;
    min-height: 1px;
    &:last-of-type {
      float: right;
    }
  }
}

.full-md-less {

  @include mq(medium-less) {
    width: 100%;
  }
}

// ==========================================================================
// Mixins
// ==========================================================================

@if variable-exists(font-url) {
    @import url($font-url); 
}

@function g-context($g-col-width, $g-col-count ,$g-gutter-width) {
  $g-context: ($g-col-width * $g-col-count) + ($g-gutter-width * ($g-col-count - 1));
  @return $g-context;
}


//Media queries

@mixin mq($break) {
    @if $break == "small" {
        @media (min-width: $brk-sm) and (max-width: $brk-md) {
            @content;
        }
    }

    @else if $break == "medium-less" {
        @media(max-width: $brk-lg){
            @content;
        }

    }

    @else if $break == "medium" {
        @media(min-width: $brk-md + 1){
            @content;
        }

    }
    @else if $break == "large" {
        @media(min-width: $brk-lg){
            @content;
        }
    }
    @else {
        @error "Error, No value could be retrieved for '#{$break}' "
    }
}

@mixin doubly($margin: 1em) {
    & + & {
      margin-left: $margin;
    @content;
    }
}

// Grid

$g-col-width    : 65px;
$g-gutter-width : 30px;
$g-col-count    : 12;
$g-cont-max-w   : 1100px;


// Breakpoints

$brk-sm     : 1px;
$brk-md     : 768px;
$brk-lg     : 1080px;
