Frequently Asked Questions & Guide
What is Flexbox?
Flexbox (Flexible Box Layout) is a 1D layout model in CSS that handles item distribution along a single axis (horizontal or vertical) with alignment and sizing capabilities.
How does flex-direction affect layout alignment?
Changing `flex-direction` to `column` switches the main axis to vertical, meaning `justify-content` aligns items vertically, and `align-items` aligns them horizontally.
When should I use flex-direction: row-reverse?
Use `row-reverse` when you want to reverse the display order of items (e.g. from right-to-left) without altering the HTML structure.
