1-B 2-B 3-B 4-B | 5 = gap 6 = cross 7 = .nav{display:flex;justify-content:space-between;align-items:center;} 8 = It lets the item grow/shrink to fill available space proportionally relative to sibling flex items 9 = Set flex-direction: column on the container | 10 = .cards{display:flex;flex-wrap:wrap;gap:1rem;} .cards>div{flex:1 1 300px;} — flex-wrap allows wrapping and flex-basis(300px) controls when cards drop to a new line.
