About the CSS Flexbox Generator Tool

This CSS Flexbox Generator is a practical tool that helps you build modern, responsive layouts with ease. Experiment in real time with properties like flex-direction, flex-wrap, justify-content, and align-items to see exactly how each change affects your design.

What is Flexbox?

Flexbox, or CSS Flexible Box Layout, is a layout model that makes it easier to design flexible, responsive web layouts. It allows you to align and distribute space among items in a container even when their size is unknown or dynamic.

Container Properties

  • display: Determines the type of flex container. Choose flex for block-level containers or inline-flex for inline containers.
  • flex-direction: Sets the direction of the flex items. Use row or row-reverse for horizontal alignment, and column or column-reverse for vertical stacking.
  • flex-wrap: Controls whether items should wrap to a new line. With nowrap all items remain on a single line, while wrap or wrap-reverse allows items to flow onto multiple lines.
  • justify-content: Aligns items along the main axis (horizontal in a row, vertical in a column). Options like flex-start, flex-end, center, space-between, space-around, and space-evenly help you distribute space evenly.
  • align-items: Aligns items along the cross axis. Use settings such as flex-start, flex-end, center, baseline, or stretch to control vertical alignment (or horizontal, if in a column).
  • align-content: When wrapping occurs, this property controls the spacing between lines of flex items. It works similarly to justify-content but on the cross axis.
  • gap: Specifies the spacing between flex items, providing an easy way to create uniform space without extra margin settings.

Flex Item Properties

  • flex-grow: Dictates how much a flex item will grow relative to the other items in the container. A higher number means more growth.
  • flex-shrink: Controls how flex items shrink when there isn't enough space, helping to prevent overflow.
  • flex-basis: Sets the initial size of a flex item before space is distributed according to the growth or shrink values.
  • order: Allows you to change the order of the flex items without altering the HTML structure. This means you can rearrange items simply by adjusting their order value.
  • align-self: Overrides the container's align-items property for individual items, giving you more granular control over each element's alignment.
  • width & height: Define the dimensions of each flex item to ensure they maintain a consistent and intentional layout.

This tool helps developers and designers simplify their workflow while learning CSS flexbox. Adjust the properties, see changes immediately, and create layouts that are both stylish and functional across all devices.
