The direct child elements of a flex container automatically becomes flex items.
Flex items can have the following properties:
- order - Specifies the display order of the flex items inside the flex container
- flex-grow - Specifies how much a flex item will grow relative to the rest of the flex items
- flex-shrink - Specifies how much a flex item will shrink relative to the rest of the flex items
- flex-basis - Specifies the initial length of a flex item
- flex - Shorthand property for flex-grow , flex-shrink , and flex-basis
- align-self - Specifies the alignment for the flex item inside the flex container
CSS order Property
The order property specifies the display order of the flex items inside the flex container.
The first flex item in the source code does not have to appear as the first item in the layout.
The order value must be a number, and the default value is 0.
orderCSS flex-grow Property
The flex-grow property specifies how much a flex item will grow relative to the rest of the flex items.
The value must be a number, and the default value is 0.
<div class="flex-container"> <div style="flex-grow: 1">1</div>
<div style="flex-grow: 1">2</div> <div style="flex-grow: 4">3</div> </div>CSS flex-shrink Property
The flex-shrink property specifies how much a flex item will shrink relative to the rest of the flex items.
The value must be a number, and the default value is 1.
<div class="flex-container"> <div>1</div> <div>2</div> <div style="flex-shrink: 2">3</div>
<div>4</div> <div>5</div> <div>6</div> </div>CSS flex-basis Property
The flex-basis property specifies the initial length of a flex item.
<div class="flex-container"> <div>1</div> <div>2</div> <div style="flex-basis: 250px">3</div>
<div>4</div> </div>CSS flex Property
The flex property is a shorthand property for the flex-grow , flex-shrink , and flex-basis properties.
<div class="flex-container"> <div>1</div> <div>2</div> <div style="flex: 1 0 150px">3</div>
<div>4</div> </div>CSS align-self Property
The align-self property specifies the alignment for the selected item inside the flexible container.
This property overrides the default alignment set by the container's align-items property.
In these examples we use a 200 pixels high container, to better demonstrate the align-self property:
<div class="flex-container"> <div>1</div> <div>2</div> <div style="align-self: center">3</div>
<div>4</div> </div><div class="flex-container"> <div>1</div> <div style="align-self: flex-start">2</div>
<div style="align-self: flex-end">3</div>
<div>4</div> </div>The CSS Flex Items Properties
