Why should you use the Responsive Flexbox Grid?
FlexGrid provides simpler and more flexible layout options in CSS. More specifically, it provides:
– Easy vertical alignment of content within a parent element.
– Easy reordering of content across devices and screen resolutions with the help of media queries
– Easy CSS-only equal height columns for your grid-based layouts
All these things are possible outside flexbox, but typically require extra hacks and workarounds to do right.
