Header

Alpha
Use the Header component to create a header that has all of its items aligned vertically with consistent horizontal spacing

Examples

All items directly under the Header component should be a Header.Item component. Inside these components can be anything (text, forms, images...), and the Header.Item component will make sure these elements vertically align with each other.

Header.Item elements have a built-in margin that will need to be overridden with the mr={0} props for the last element in the container. We relied on the prop here instead of :last-child because the last child isn't always the item visible. On responsive pages, there's a mobile menu that gets presented to the user at smaller breakpoints.
