A comprehensive understanding of the purpose of flex

1. You can use flex to layout one div in another div horizontally and vertically center

For example: html code:

<div class="container">
	<div class="box">

	</div>
	</div>

css code:

.container{
	width:600px;
	height:400px;
	border:1px solid blue;
	display: flex;
	justify-content:center;
	align-items:center;
	}
	.box{
	width:200px;
	height:100px;
	border:1px red solid;

ps: This way you can center horizontally and vertically

2. The properties of flex

<div class="items">
	<div class="item">1</div>
	<div class="item">23</div>
	<div class="item">4</div>
	</div>

There are six attributes that can be written on items:

•flex-direction
•flex-wrap
•flex-flow
•justify-content
•align-items
•align-content

There are 6 that can be written on the item:

•order//This is given to the item separately. If you want the item to change the order, give this attribute to the item.
•flex-grow
•flex-shrink
•flex-basis
•flex
•align-self
