What is the difference between flex: 1 and flex: auto?
Difference Between flex: 1 and flex: auto
The flex shorthand property allows you to control the growth, shrinkage, and base size of flex items. flex: 1 and flex: auto are common shorthand values but differ in how they treat the base size of items.
Key Differences
flex: 1→ Equivalent toflex: 1 1 0;. The item grows to fill available space, can shrink if needed, and starts from a base size of 0.flex: auto→ Equivalent toflex: 1 1 auto;. The item grows and shrinks likeflex: 1, but its base size is its content's intrinsic size (auto).
Essentially, flex: 1 ignores the content size initially, distributing all extra space equally, whereas flex: auto respects the intrinsic size of the item before distributing remaining space.
