Everything you need to know about how this utility processes data safely in your browser.
When should I use Flexbox vs CSS Grid?
Use Flexbox for 1-dimensional layouts (a row of buttons or a single navigation bar) and CSS Grid for 2-dimensional multi-column/multi-row layouts.
How does `align-items` differ from `justify-content`?
`justify-content` aligns items along the primary axis, while `align-items` aligns along the cross axis.
