Foundation 5's block grids for Bootstrap 3.
// # Block Grid
// Technique adapted from Foundation 5 for Bootstrap 3.0.3 to at least 3.3.1.
// # 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;
.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));
@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) }

@Remo: Thanks for pointing that out. I'm guessing you're using Bootstrap 3.0.0. It seems like @screen-sm-min was a variable added shortly after Bootstrap 3.0.0. @screen-sm is deprecated as of 3.0.1.

@corlletelab: Good point. I've taken your suggestion!

@taydakov: Thanks for sharing an example of usage. That's important info, so I've updated the Gist with an example.

In case this helps: If you're using the CSS version of Bootstrap but are incorporating your own styles in LESS and want to use this, these are Bootrstrap's default values for the variables needed.

@grid-columns: 12;
@grid-gutter-width: 30px;

@screen-sm-min: 768px;
@screen-md-min: 992px;
@screen-lg-min: 1200px;

How can we add space between these grid items without it breaking? I am trying margin-right: 20px; but that doesnt seem to be working in my favor

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) {}



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?
