justify-content

• reference: https://developer.mozilla.org/en-US/docs/Web/CSS/justify-content
• defines how the browser distributes space between and around content items along the main-axis of a flex container, and the inline axis of a grid container
• The alignment is done after the lengths and auto margins are applied, meaning that, if in a Flexbox layout there is at least one flexible element, with flex-grow different from 0, it will have no effect as there won't be any available space.
