Flex, Box, or Flexbox: Which Display Value Should You Use?

The Flexible Box Model: Navigating 'flex', 'box', and 'flexbox' Values

The advent of the flexible box model introduced a paradigm shift in CSS3, phasing out传统的 display 属性值，such as inline and block. However, the flexible box model is often presented with various values, including flex, box, and flexbox. This article delves into the differences between these values and provides guidance on their usage.

Display: flex

Display: flex is the current standard value. It supports modern browsers, including Chrome 29 , Firefox 22 , Safari 7 , and Internet Explorer 11 . Flex provides advanced capabilities for layout management, including the ability to align and distribute items along both horizontal and vertical axes.

Display: box

Display: box is an older value that was introduced earlier in the development of the flexible box model. It is supported in most major browsers with vendor prefixes but is generally phased out in favor of display: flex.

Display: flexbox

Display: flexbox is another intermediate value that was introduced to bridge the transition from display: box to display: flex. It is supported in newer browsers with vendor prefixes and is similar to display: flex in terms of functionality.

Which Value to Use?

Ultimately, the choice between these values depends on the browsers you need to support. If you require backward compatibility, consider using display: box with browser prefixes. For more modern browser support, display: flex is the recommended option.

Additional Notes

• The box spec differs significantly from the flexbox/flex specs and may not always be suitable for achieving desired results.
• Some browsers may support multiple display values. However, it is recommended to include flex properties when possible for future-proofing.
