flex-basis
We use the flex-basis property to define the default size of the flex-item before the space is distributed.
The following example demonstrates the usage of the flex-basis property. Here we are creating 3 colored boxes and fixing their size to 150 px.
<!doctype html> <html lang = "en"> <style> .box{ font-size:15px; padding:15px; } .box1{background:green; flex-basis:150px; } .box2{background:blue; flex-basis:150px;} .box3{background:red; flex-basis:150px;} .container{ display:flex; height:100vh; align-items:flex-start; } </style> <body> <div class = "container"> <div class = "box box1">One</div> <div class = "box box2">two</div> <div class = "box box3">three</div> </div> </body> </html>
It will produce the following result −
flex-grow
We use the flex-grow property to set the flex-grow factor. In case of excess space in the container, it specifies how much a particular flex-item should grow.
<!doctype html> <html lang = "en"> <style> .box{ font-size:15px; padding:15px; } .box1{background:green; flex-grow:10; flex-basis:100px; } .box2{background:blue; flex-grow:1; flex-basis:100px; } .box3{background:red; flex-grow:1; flex-basis:100px; } .container{ display:flex; height:100vh; align-items:flex-start; } </style> <body> <div class = "container"> <div class = "box box1">One</div> <div class = "box box2">two</div> <div class = "box box3">three</div> </div> </body> </html>
It will produce the following result −
flex-shrink
We use the flex-shrink property is used to set the flex shrink-factor. In case there is not enough space in the container, it specifies how much a flex-item should shrink.
<!doctype html> <html lang = "en"> <style> .box{ font-size:15px; padding:15px; } .box1{background:green; flex-basis:200px; flex-shrink:10} .box2{background:blue; flex-basis:200px; flex-shrink:1} .box3{background:red; flex-basis:200px; flex-shrink:1} .container{ display:flex; height:100vh; align-items:flex-start; } </style> <body> <div class = "container"> <div class = "box box1">One</div> <div class = "box box2">two</div> <div class = "box box3">three</div> </div> </body> </html>
It will produce the following result −
flex
There is a shorthand to set values to all these three properties at once; it is called flex. Using this property, you can set values to flex-grow, flex-shrink, and flex-basis values at once. Here is the syntax of this property.
.item { flex: none | [ <''flex-grow''> <''flex-shrink''>? || <''flex-basis''> ] }
