How the CSS Flexbox Generator Works
Our CSS Flexbox Generator online helps you create fully responsive layouts in seconds, without memorizing any CSS. The tool uses flex containers and flex items to structure your layout visually.
Container Properties define the layout:
  • display: flex – enables Flexbox
  • flex-direction – row or column
  • flex-wrap – nowrap, wrap, or wrap-reverse
  • justify-content – align items along the main axis
  • align-items – align items along the cross axis
  • align-content – spacing for multiple lines
  • gap – spacing between items
Item Properties control individual elements:
  • flex – shorthand for flex-grow, flex-shrink, and flex-basis
  • align-self – override container alignment
  • order – rearrange items visually
Live Preview:
 See changes instantly as you adjust properties. Once satisfied, copy CSS code directly to your project.
Tip: Beginners can experiment freely every adjustment updates the live preview, helping you learn Flexbox visually.
