This was a bit unexpected. It appears when setting a value on one of the Margins in a Div contained within a section, it’s outputting the 0 values and shifting the layout. (Whereas, typically the 0 values in CS are ignored altogether – right?)
Anyway, here’s the hierarchy.
Section
* Div
** Text
** Text
The Div has the following settings changed from default:
- Global Container: True
- Flexbox : True
- Direction: Row
- Wrap: Off
- Vertical: Baseline
- Margine: True
- Margin Link Sides: OFF
- Margin Bottom: 1em
- Margin Top, Right, Left: 0em
You can see it pinned to the 0 value to the left of the screen here.
