FAQ
- When should I use place-items: center?
- It is a modern shorthand for CSS Grid layout to center elements both horizontally and vertically in just one line of code.
- What are the limitations of using vertical-align?
- The vertical-align property only works on inline or table-cell elements, and often requires pairing with a line-height hack to align nested divs.
- When is the absolute-positioning method the right choice for vertical alignment?
- The top: 50% plus transform: translateY(-50%) combination is handy when you can't change the parent's layout (say, it's not set up as flex or grid) but still need to position a single child element. Keep in mind it takes the element out of normal document flow, so overusing it can easily break your layout.
