working like a charm. thanks.
I never try to use any of layout option before. how does it different than 1, 1/2, 1/3, … option on the element top left corner?
BTW, I notice there is small padding to the size when screen size drop below 767px.
#page-wrap {
padding: 0 5px;
}
which make it no longer full size. (p.s. I removed all the spacing and padding)
