Many thanks for getting back, i apologise for the delay.
I must admit i hadn't thought of what joe's video explained and thought this was a cool way to get around the problem of spacing, even though i had just re-downloaded your spacer stack again, and decided to give joe's idea of padding and margins a go.
I'm creating a community / town website where i live in Eastern France which currently runs to 32 pages.
So went ahead and decided to use joe's method for the first 4 pages to see how i got along, and i must say it was ok, but a little time consuming in relation to adding a spacer stack, then adding the given pixels and moving onto the next part. But after a complete day redoing the 4 pages i have decided to go back to the spacer stack, so much simpler, for me anyway.
It was a little like moving from Photoshop to Gimp for example. After 20 years as a Photoshop user trying to work with gimp, or any other image software just doesn't feel right, trying to get to know the in's and out's of a new software package doesn't feel easy.
I've always used Spacer and found that it suits my workflow perfectly. Each to there own as the saying goes.
As for the technicalities and whats under the hood of the Spacer stack i'll leave that to you the developers. It work's perfectly for what i want.
Once again many thanks for the response and taking the time.
All the best
