The Mental Shortcut for Mastering CSS Flexbox

Have you ever stared at a CSS Flexbox problem and felt like you were reading another language? You aren't alone. Let's break down exactly why this trips up so many students.

The Contrast Technique

To build your intuition, contrast a failure against a success.

Failure: applying justify-content to the child instead of the parent.

Success: Flexbox properties like justify-content and align-items MUST be applied to the parent container (`display: flex;`), not the individual child items you want to move..

By comparing the two, the shortcut becomes obvious. You aren't doing less work; you are doing more efficient work.
