A common problem in apps is when active elements have active areas the size of the content.
For example, a small text at around 12px will be easy to miss when tapped. Apart from this, it presents anxiety to the user that he/she might miss it when it needs to be tapped.
The solution is simply increasing the size of the active area thru Padding.
