Extended from bootstrap spacing
Each spacing class is named for the percentage of the base size (16px) that generates the associated pixel value.
For example, 32px is 200% of 16px, so the classes are named p-200 m-200.
p-0 m-0p-25 m-25p-50 m-50p-100 m-100p-150 m-150p-200 m-200p-300 m-300p-400 m-400p-500 m-500p-600 m-600p-800 m-800
