title: bootstrap grid with 24 cols and 12 cols on the same page
body: <p>I have a question about bootstrap's grid system.
  I need in the same page 2 grids - row with 12 cols and row with 24 cols.</p>
  
  <p>In row with 24 cols i have 3 elements - with 1 cols, with 20 cols and with 3 cols.
  I can not split 2th element (with 20/24) as Gleb Kemarsky mention <a href="https://stackoverflow.com/a/38384830/4527967">here</a></p>
  
  <p>I need in the same page grid with normal (12 cols), so i can not use bootstrap's @grid-columns 's variable. As zessx mention <a href="https://stackoverflow.com/a/26679237/4527967">here</a></p>
