Getting Started with Skeleton, the Simple CSS Boilerplate

The row class is just for clearing floats around the columns. Skeleton provides the following code snippet:

.container:after, 
.row:after,
.u-cf {
  content: "";
  display: table;
  clear: both; }

That means, if you want, you can structure your HTML without including the row class. However, in this case you should clear the floats around your columns. To do this, you can use the helper u-cf class as a wrapper for your columns.
