// GRID SYSTEM
// -----------
// To customize the grid system, bring up the variables.less file and change the column count, size, and gutter there

.row {
  .clearfix();
  margin-left: -@gridGutterWidth;
}

// Find all .span# classes within .row and give them the necessary properties for grid columns (supported by all browsers back to IE7)
// Credit to @dhg for the idea
.row > [class*="span"] {
  .gridColumn();
}

// Default columns
.span1     { .columns(1); }
.span2     { .columns(2); }
.span3     { .columns(3); }
.span4     { .columns(4); }
.span5     { .columns(5); }
.span6     { .columns(6); }
.span7     { .columns(7); }
.span8     { .columns(8); }
.span9     { .columns(9); }
.span10    { .columns(10); }
.span11    { .columns(11); }
.span12    { .columns(12); }
.span13    { .columns(13); }
.span14    { .columns(14); }
.span15    { .columns(15); }
.span16    { .columns(16); }

// For optional 24-column grid
.span17    { .columns(17); }
.span18    { .columns(18); }
.span19    { .columns(19); }
.span20    { .columns(20); }
.span21    { .columns(21); }
.span22    { .columns(22); }
.span23    { .columns(23); }
.span24    { .columns(24); }

// Offset column options
.row {
  & > .offset1   { .offset(1); }
  & > .offset2   { .offset(2); }
  & > .offset3   { .offset(3); }
  & > .offset4   { .offset(4); }
  & > .offset5   { .offset(5); }
  & > .offset6   { .offset(6); }
  & > .offset7   { .offset(7); }
  & > .offset8   { .offset(8); }
  & > .offset9   { .offset(9); }
  & > .offset10  { .offset(10); }
  & > .offset11  { .offset(11); }
  & > .offset12  { .offset(12); }
}

// Unique column sizes for 16-column grid
.span-one-third     { width: 300px; }
.span-two-thirds    { width: 620px; }
.offset-one-third   { margin-left: 340px; }
.offset-two-thirds  { margin-left: 660px; }
