align items vs justify content code example

Example 1: flexbox align right and left

.primary-nav {
    display:-webkit-flex;
    display:flex;
    list-style-type:none;
    padding:0;
    justify-content:flex-end;
}

.left {
    margin-right:auto;
}

Example 2: flex align children to side

flex-direction: column;
align-items: flex-start; //left
align-items: center; //center
align-items: flex-end; //right

Example 3: justify-content vs align-items

(Note: The X and Y axis / alignment direction can change depending 
if you are using flex-direction: row or column)

1. justify-content: Horizontal-X-axis
Alignment & Spacing along primary axis (X-axis)

flex-start; Align children horizontally left

flex-end; Align children horizontally right

center; Align children horizontally centered (amaze!)

space-between; Distribute children horizontally evenly across
entire width

space-around; Distribute children horizontally evenly across 
entire width (but with space on the edges

2. align-items: Vertical-Y-axis
Alignment only along secondary axis (Y-axis)

flex-start; Align children vertically top

flex-end; Align children vertically bottom

center; Align children vertically centered (amaze!)

baseline; Aligned children vertically so their baselines align 
(doesn't really work)

stretch; Force children to be height of container (great for columns)
