css flexbox syntax

Display: flex 
Flex-direction: row | row-reverse | column | column-reverse
align-self: flex-start | flex-end | center | baseline | stretch
justify-content: start |  center | space-between | space-around | space-evenly

.item {
  align-self:flex-start | flex-end | center | baseline | stretch;
}

.container {
	display: flex;
}

Anything within the container that is a block level element is
now turned into an inline element only taking up the space of 
its actual content placing all items side by side instead on
individual rows.

<div class="flex-container">
  <div>1</div>
  <div>2</div>
  <div>3</div>
</div>
<style>
  .flex-container {
  display: flex; // default: flow
  flex-direction: column; // elements in a column
}
</style>
