During the CSS Stone Age, developers used floats and positioning for layouts until the introduction of Flexbox. Flexbox revolutionized layout design by allowing developers to create flexible layouts. To use Flexbox, you need a container with child elements in your HTML. In CSS, you set the container's display property to "flex," creating a main and cross axis. You can align items along the main axis with "justify-content" and along the cross axis with "align-items." "Flex-direction" determines the main axis orientation.
By default, items try to fit in one line, but you can enable wrapping with "flex-wrap." When using wrapping, "align-content" helps align items on the cross axis. You can add gaps between items with the "gap" property. Flex properties like "flex-grow," "flex-shrink," and "flex-basis" control item sizing. "Align-self" overrides "align-items" for individual items. The "order" property changes the order of items but should be used sparingly due to its impact on accessibility and semantics.
Sure, here are the key facts extracted from the provided text:
1. During the CSS Stone Age, developers were creating layouts with floats and positioning.
2. Flexbox was introduced and changed the world of web layout.
3. To use flexbox, you need a container and children in your HTML.
4. The "display: flex" property creates two invisible axes: a main axis and a cross axis.
5. The main axis is horizontal by default but can be changed to vertical with the "flex-direction" property.
6. "justify-content" property aligns items along the main axis (default is "flex-start").
7. "align-items" property aligns items along the cross axis (default is "stretch").
8. "align-content" property aligns content on the cross axis when "flex-wrap" is set to "wrap".
9. You can add gaps between items using the "gap" property on the container.
10. "flex-grow" property allows items to grow if there's enough space.
11. "flex-shrink" property controls how fast an item shrinks relative to others.
12. "flex-basis" defines the size of an item before space distribution.
13. "flex" is a shorthand property combining growth, shrink, and basis.
14. "align-self" property overwrites "align-items" for individual items.
15. "order" property changes the order in which items appear (default is 0).
These facts provide an overview of key concepts related to CSS flexbox and its properties.
