Buttons and LinksĀ
It is important that the buttons have enough space between them and the text or any other component inside the design. This lets people see the button faster if it is too close to something then it might become a bit more difficult to see. Because links are the same they should have enough space between them and the other text, so it makes it easier to find. Links are often the same font as the rest of the design it is important to make it stand out, so people are able to spot it with ease.
