Hi Steve - I did container within columns from the start. To get the same way just using column causes the "issue" to achieve the same layout.
I really would appreciate if you still could get a video up because I think this is beneficial for many users. There is a basic difference to design in RLMP with columns only, with a mix of columns (some have a container inside, some have not), and all containers have a container inside.
From the content point of view, both column and container, can hold anything, however, the relation of these placeholders makes a difference. I think you many confirm, that when I make a column white, the columns will be next to each other and that makes it appear one white row. One can do some tricks with margin and push and pull, but it seems to be better to drop a container inside a column for total control down to pixel of a layout unless you have always the same background and the columns and float inside as the browser dimension pleases.
Thanks for the subgrid trick.
Learning by doing, the best. Nice examples in youtube by the way. All done using columns only.
Will see you again on some other issue. One is still open is the slider issue I have, any slider. Only cssSlider was working but not with all features. Maybe it is a CSS issue.
Kind regards.
