Mastering CSS Flexbox

Flex Direction

Defines the direction in which items are placed in the container.

  • row: Default. Left to right.
  • row-reverse: Right to left.
  • column: Top to bottom.
  • column-reverse: Bottom to top.

Justify Content

Aligns items along the main axis (horizontal if row, vertical if column).

  • flex-start: Items packed to start.
  • center: Items centered.
  • space-between: Evenly distributed, first/last at edges.

Align Items

Aligns items along the cross axis (vertical if row, horizontal if column).

  • stretch: Stretch to fill container (if no fixed size).
  • center: Cross-axis centered.
  • flex-start: Cross-axis start.

Flex Wrap

Controls whether items forced onto one line or can wrap onto multiple lines.

  • nowrap: All items on one line.
  • wrap: Items wrap to next line if needed.

The CSS Flexbox Playground is an interactive tool to help you master CSS Flexbox. Flexbox is a powerful layout module, but remembering all the properties like `justify-content`, `align-items`, and `flex-wrap` can be tricky.

With this tool, you can visually toggle settings and see the results instantly. Add items, change their size, and experiment with different alignments. Once you have the perfect layout, copy the generated CSS code directly into your project.

Frequently Asked Questions

When should I use Flexbox vs CSS Grid?

Use Flexbox for one-dimensional layouts (rows OR columns), like navigation bars, card lists, or centering elements. Use CSS Grid for two-dimensional layouts (rows AND columns), like page layouts or complex grids. Many designs use both together.

Does Flexbox work in Internet Explorer 11?

IE11 has partial Flexbox support with the 2012 syntax. Most Flexbox properties work, but some features like 'gap' are not supported. For IE11 compatibility, use margins instead of gap and test thoroughly.

What are the most common Flexbox patterns?

Common patterns include: centering (align-items: center; justify-content: center), equal-width columns (flex: 1 on children), space-between navigation (justify-content: space-between), and sticky footer (flex-direction: column with min-height: 100vh on body).
