How to center a box using HTML

Centering a box is easy using a CSS stylesheet in HTML. There are two main ways to achieve box centering:

Horizontal centering

1. Settingstext-align: center; Style: This is The simplest way to horizontally center a block-level element such as div, h1, or p.
2. Use margin: auto; style: This method is suitable for non-block-level elements (such as inline elements), such as images or embedded videos. It will automatically set the left and right margins of the element so that it is centered.

Vertical center

1. Use margin: 0 auto; Style: This style sets the left and right margins of the element to 0 and center it vertically.
2. Use the position: absolute; style: This style removes the element from the normal document flow and allows you to use the top and left attributes to absolutely position it. You can then set these properties to 50% and offset the element using transform: translate(-50%, -50%); to center it.

Example

The following example shows how to center a box horizontally and vertically using HTML and CSS:

<div style="text-align: center; margin: 0 auto;">
  <p>这是一个水平和垂直居中的盒子。</p>
</div>

Note :

• Make sure the container element has enough height or width to accommodate the centered element.
• For complex layouts, you may need to use a combination of horizontal and vertical centering techniques.
• For cross-browser compatibility, be sure to specify a prefix in each style (such as -webkit-, -moz-).
