Padding
Many components in Ionic purposely have both padding and margin reset set to zero. In many instances apps will have components bleed to the edge of the screen, and by starting each component at zero developers can easily control padding and margins throughout the app.
The padding
utility classes can be reused to give any element's content some breathing room, meaning it adds a default 10px
between the outer box of the element and its inner content. The following classes are not required for any element, but may be helpful with your layout.
