Frequently asked questions

Do I need to know CSS basics before flexbox?

A little. If you can write a class selector and set properties like color or padding, you are ready — flexbox is just a set of properties on a container and its children.

Is flexbox still worth learning with CSS Grid available?

Yes. Flexbox excels at one-dimensional layout (a row or a column) and is the right tool for navbars, toolbars, and centering; Grid handles two-dimensional layouts. Most sites use both.
