A web developer needs to create a layout where each child element occupies an equal amount of space, regardless of its content. Which display property should they use, Flexbox or Grid, and why?

  • Both Flexbox and Grid
  • Flexbox
  • Grid
  • Neither Flexbox nor Grid
In this scenario, Flexbox is the preferred choice because it is designed for one-dimensional layouts, making it ideal for distributing space along a single axis, ensuring each child element gets an equal amount of space regardless of content.
