Comments ladders with limited nesting

In short

#comments .c .c
{
margin-left: 20px;
}

#comments .c .c .c .c .c .c .c .c .c .c .c
{
margin-left: 0px;
}


Little more detail

Sometimes you can not even consider the nesting of comments on the server and not assign them their classes like indent_1, indent_2, indent_3, and so on.
