Overview

The flex-basis property specifies the initial length of a flex item.

Specify the Initial Length of Items

In the following, the three boxes have no specific width defined and are the width of their content (the text within each box).

				
					<div class="flex_container">
    <div class="div_1">Box 1</div>
    <div class="div_2">Box 2</div>
    <div class="div_3">Box 3</div>
</div>
				
			
				
					.flex_container {
    display: flex;
    background-color: #ffbd02;
}
.flex_container > div {
    background-color: #eaeaea;
    margin: 10px;
    padding: 20px;
    font-size: 22px;
}
				
			
Box 1
Box 2
Box 3

However, if we add lines 11 through 19, we can define a width for that particular flex item.

				
					.flex_container {
    display: flex;
    background-color: #ffbd02;
}
.flex_container > div {
    background-color: #eaeaea;
    margin: 10px;
    padding: 20px;
    font-size: 22px;
}
.div_3 {
	flex-basis: 300px;
}
				
			
Box 1
Box 2
Box 3
