Fixes #8804 - Align the dashboard to bootstrap columns

@ShimShtein This is merged already, but now that I think about it, isn't it possible to move this data-sizex up? 

Something like 
```scss
@for $i from 1 through 12 {
  [data-col="#{$i + 1}", data-sizex="#{$i}"] {
```

Feel free to resubmit a PR referencing this issue number if you think this can be DRYed up a bit more.
