This article is about how to use the flex-basis attribute in css. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Definition and usage

The flex-basis property is used to set or retrieve the flex reference value of the elastic box.

Note: if the element is not an element of the elastic box object, the flex-basis attribute has no effect.

Default value: auto

Inheritance: no

Animated: yes.

Version: CSS3

JavaScript syntax:

Object.style.flexBasis= "200px"

CSS syntax

Flex-basis:number | auto | initial | inherit

Attribute value

Number A unit or percentage of length that specifies the initial length of a flexible project.

Auto default value. Length is equal to the length of a flexible project. If the project does not specify a length, the length is determined based on the content.

Initial sets this property to its default value.

Inherit inherits this attribute from the parent element.

Case study

Set the initial length of the second elastic box element to 80 pixels:

# main {

Width:350px

Height:100px

Border:1pxsolid#c3c3c3

Display:-webkit-flex;/*Safari*/

Display:flex

}

# maindiv {

-webkit-flex-grow:0;/*Safari6.1+*/

-webkit-flex-shrink:0;/*Safari6.1+*/

-webkit-flex-basis:40px;/*Safari6.1+*/

Flex-grow:0

Flex-shrink:0

Flex-basis:40px

}

# maindiv:nth-of-type (2) {

-webkit-flex-basis:80px;/*Safari6.1+*/

Flex-basis:80px

}
