Foundation 5's block grids for Bootstrap 3.

block-grid.less

// # Block Grid
//
// Technique adapted from Foundation 5 for Bootstrap 3.0.3 to at least 3.3.1.
// https://github.com/zurb/foundation/blob/f755d8704123f86c281ede0b171881e2672f150d/scss/foundation/components/_block-grid.scss
//
// # Example Usage
//
// To produce a grid of 2 items per row on an extra-small screen, and 3 items
// per row on a small screen:
//
//     <div class="block-grid-xs-2 block-grid-sm-3">
//         <div class="block-grid-item">
//             ...
//         </div>
//     </div>

[class*="block-grid-"] {
  display: block;
  margin: -(@grid-gutter-width/2);
  padding: 0;
  .clearfix();
}

.block-grid-item {
  display: inline;
  margin: 0;
  padding: (@grid-gutter-width/2);
  height: auto;
  float: left;
  width: 100%;
  list-style: none;  // for those who like to use `li` elements as block-grid-items
}

.block-grid (@per-row) {
  & > .block-grid-item {
    width: (100%/@per-row);

    @nth-equation: ~"@{per-row}n+1";
    &:nth-of-type(n) { clear: none; }
    &:nth-of-type(@{nth-equation}) { clear: both; }
  }
}

// Recursive loop that produces rules for block grids of @per-row many items
// per row down to 1 many items per row.
.block-grids(@size, @per-row: @grid-columns) when (@per-row > 0) {
  .block-grid-@{size}-@{per-row} { .block-grid(@per-row); }
  .block-grids(@size, (@per-row - 1));
}

.block-grids(xs);
@media (min-width: @screen-sm-min) { .block-grids(sm) }
@media (min-width: @screen-md-min) { .block-grids(md) }
@media (min-width: @screen-lg-min) { .block-grids(lg) }

This is exactly what I was looking for. Any idea how it could be updated to be used as a LESS mixin?

For example using LESS to change font-size;

.myFontSize(@size) { font-size: ~"@{size}px"}

.myFontClass (@size) {
   (~".font@{size}") { .myFontSize(@size); }
}

//////////////////////////////////////////////////////

.loop (@index) when (@index >= 10) {
    .myFontClass (@index);
    .loop(@index - 1);
} 
.loop (@index) when (@index < 10) {}

Usage:

.title{
    margin-bottom:0.5em;
    .myFontSize(13);
}

Output CSS

.title {
  margin-bottom: 0.5em;
  font-size: 13px;
}

I tried this sass mixin but the li with thumbnails still has the padding at left and right for first child and last child. Is there any way for me to set padding-left and padding-right at 0 for first child and last child in grid?

I've created a new repo: https://github.com/JohnnyTheTank/bootstrap-block-grid

Thank you very much for this information! I really need something like that in bootstrap project now!

Does it need to be inside a .row ? Thanks!

Nice! Thanks for sharing.
