When I use a standard divider, the spacing is too wide, perhaps too “thick” is the correct wording.
I use the controls to adjust all way down to 1 pixel…still it seems the "buffer area is too wide (thick).
How am I screwing this up?
That “buffer” area is margin. You can look in the inspector to get the divider class then add it to your class manager. Or you can use bootstrap classes straight on the divider
Eg
.my-0
Will remove the margin top and bottom. You can set the 0 to 1 through to 5 to vary the margin.
Click inside the box . You should see now a blinking cursor. Once the cursor is blinking you type on your keyboard my-0 and press enter. Now the name: my-0 should visible on a pill–shape grey background. If nothing happens you’ve most likely made an error in the sequence above and you should start all over from step 1 .
