This article will introduce to you how to center a div horizontally and vertically on the screen. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.
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tag, but it is outdated.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Since the center tag is outdated, it is not recommended to use it in a formal way.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>
