Checklists are everywhere. They let you display a set of terms, phrases, or statements clearly, and prevent reader fatigue or confusion. Check comes with 43 hand picked vector based checkmarks for you to choose from, to further reinforce your list items.
Having a left gutter on your list items helps reinforce readability, and it looks great, well at least on a screen of any sizeable width. But once the screen size gets very small, that left gutter starts to look completely out of place. Check responds accordingly, allowing your content to push all the way left on smaller screens, so it always looks great.
