Flex layout
Basics
If “regular” layout is based on both block and inline flow directions, the flex layout is based on “flex-flow directions”.
Flex properties
Direction
This establishes the main-axis, thus defining the direction flex items are placed in the flex container. Flexbox is (aside from optional wrapping) a single-direction layout concept.
.container {
flex-direction: row | row-reverse | column | column-reverse;
}
Align self
Issue: Flexbox "align-items : center" shrinks a child's max-width[1]
.container {
align-self: center;
max-width: 200px;
width: 100%;
}
