well... I've come to figure out
---- that Sections can exist within another Container Element
---- like a Container or a Table.
I was trying to figure out how to utilize "Sections" when your website has multiple "types of products".
For example... hand tools vs power tools.
Sections are "suppose to group" your data / products... but there's a clear different between hand tools and power tools.
So I decided... let's just create a "tools" section. Within that - I add a container and a 2 column table.
Within the table - I was able to add 2 sections - 1 per column.
This allowed me to use (section off) a column for hand tools and another section for power tools.
Doing it this way... I was able "section" "my products".
So in short... I was incorrect in my statement. Sections do not have to span 100% of the page.
They appear to span 100% of the parent container. If it's a body element - then it's 100% of the page. If it's a column... a section will span 100% of the column. Same with a section inside a container.... spans 100%.
