Comprehensive understanding of the uses of flex

1. You can use flex to lay out a div and center it horizontally and vertically inside another div.

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 it horizontally and vertically

2. Flex properties

<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 items that can be written on the item:

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