Twitter bootstrap documentation talks about three mixins to generate grid systems:
.container-fixed();
#grid > .core();
#grid > .fluid();
I know how to setup the page to use bootstrap and less... But I don't know how to use the grid system semantically. The documentation says what mixins to use but not how... ¿ Could anyone ilustrate how to use them in order to create semantic grids ? Just to figure out or to see how it works :S
Thank you !!
