Example 3: css grid vs flexbox

/* Both flexbox and grid are based on this concept. 
Flexbox is best for arranging elements in either a single row, 
or a single column. Grid is best for arranging 
elements in multiple rows and columns. 
The justify-content property determines how the extra space of the 
flex-container is distributed to the flex-items. */
