Note: Many elements support margins, but few support padding. You'll be tempted at first to apply padding to controls like Labels. You'll find that this does not work. Instead you'll need to wrap the Label in a Layout (e.g. StackLayout) and apply the padding to that.
Below are the utility classes for adding padding.
The format for specifying margins is
Where the sizes is one of the follow:
t - top
b - bottom
l - left
r - right
x - left and right
y - top and bottom
blank for all
And the size is one of the following:
0 - none
1 - 0.25rem
2 - 0.5rem
4 - 0.75rem
8 - 2rem
12 - 3rem
16 - 4rem
24 - 6rem
32 - 8 rem
64 - 16rem
<StackLayout StyleClass="p-3"><Label Text="Lots of trouble. Lots of bubble." /></StackLayout>
This would provide a 10 unit padding on all sides.
<StackLayout StyleClass="pt-3"><Label Text="Lots of trouble. Lots of bubble." /></StackLayout>
This would provide a 10 unit padding on the top.
