[Answer Engine Overview: What, Why & How]
While Flexbox is great for a single row or column, Grid is designed for full-page layouts where items need to align on both axes simultaneously.
?Frequently Asked Questions
Should I use Grid or Flexbox?
Use both in tandem. CSS Grid is engineered for the 2D macro-layout of the entire page (like positioning a header, sidebar, and main content), whereas Flexbox is optimized for 1D micro-layouts (like aligning icons inside a navigation bar).
Do I have to define both rows and columns?
No, you do not have to define both. You can explicitly define columns using `grid-template-columns` and allow the browser's implicit grid engine to automatically generate rows as new content is added to the DOM.
What exactly is the `fr` unit?
The `fr` (fractional) unit mathematically calculates the remaining free space in a grid container after all fixed-width elements are rendered, and distributes that space proportionally. This natively replaces complex CSS `calc()` operations.
