How to center a div horizontally and vertically on the screen

Recently when writing web pages, it is often necessary to display p in the center of the screen, so I recorded several common methods, which are relatively simple.
Simply add the <center></center> tag to the horizontal center, or set margin:auto;Of course, you can also use the following method

The following two Method to plant in the middle of the screen (horizontally centered and vertically centered)
Put the demonstration html code:

<body>
	<p class="main">
		<h1 id="MAIN">MAIN</h1>
	</p>
</body>
  • Method 1:

pUse absolute layout, set margin:auto;And set the values ​​​​of top, left, right, and bottom to be equal , not necessarily all 0.

.main{
	text-align: center; /*让p内部文字居中*/
	background-color: #fff;
	border-radius: 20px;
	width: 300px;
	height: 350px;
	margin: auto;
	position: absolute;
	top: 0;
	left: 0;
	right: 0;
	bottom: 0;
}

The effect is as shown:

  • Method 2:
    It is still an absolute layout, let left and top both be 50%, which is in the horizontal direction Let the leftmost part of p be 50% away from the leftmost part of the screen, which is the same in the vertical direction, so use transform to translate 50% of its own width (height) to the left (upward), thus achieving the centering effect. The rendering is as follows Same as above.
 .main{
	text-align: center;
	background-color: #fff;
	border-radius: 20px;
	width: 300px;
	height: 350px;
	position: absolute;
	left: 50%;
	top: 50%;
	transform: translate(-50%,-50%);
}
  • Method 3:
    For horizontal centering, you can use the simplest <center></center> tag, but it is outdated. The usage is as follows:
<p><center>123</center></p>

This <center></center> tag is relative to the text in the <p></p> tag, which can be centered.

Since the center tag is outdated, it is not recommended to use it in a formal way. You can use the following method instead:

<p style="text-align:center;">123</p>
