flex is a css property.
The flex property is used to set or retrieve how the child elements of the flex box model object allocate space.
The flex property is a shorthand property for the flex-grow, flex-shrink and flex-basis properties. The default value is 0 1 auto
.
This attribute has two shortcut values: auto (1 1 auto)
and none (0 0 auto)
. It is recommended to use this attribute first instead of writing three separate attributes separately, because the browser will infer the relevant values.
Note: If the element is not a child element of the flexbox model object, the flex attribute has no effect.
Syntax:
flex: flex-grow flex-shrink flex-basis|auto;
flex-grow A number that specifies the amount the item will grow relative to other flexible items.
flex-shrink A number that specifies the amount the item will shrink relative to other flexible items.
flex-basis The length of the item. Legal values: "auto", "inherit", or a number followed by "%", "px", "em" or any other length unit.
#auto is the same as 1 1 auto.
#none is the same as 0 0 auto.
Example:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <style> #main { width:220px; height:300px; border:1px solid black; display:flex; } #main div { flex:1; } </style> </head> <body> <div id="main"> <div style="background-color:coral;">红色</div> <div style="background-color:lightblue;">蓝色</div> <div style="background-color:lightgreen;">带有更多内容的绿色 div</div> </div> </body> </html>
