使用 CSS 将元素居中的 4 种不同方法

When designing a web page or document, it is important to ensure that elements are visually balanced and positioned correctly. A common task in web development is to center an element in its container. While this may seem like a simple task, there are multiple ways to accomplish this using CSS. In this article, we’ll explore four different ways to center an element using CSS.

We'll cover techniques for using text alignment, margins, Flexbox, and CSS Grid, and discuss the pros and cons of each approach. Whether you're new to web development or looking to improve your skills, mastering these techniques will help you create visually appealing and balanced layouts for your projects.

Using text alignment properties

CSS text-align property is used to horizontally align text within a block-level element such as a paragraph or heading. This property can accept multiple values, including left, center, right, and justify.

Example

Here is an example of how to center text in a div element using the text-align attribute -

<!DOCTYPE html>
<html>
<head>
   <style>
      div {
         text-align: center;
      }
   </style>
</head>
<body>
   <div>
      <h1 id="Welcome-to-my-website"> Welcome to my website </h1>
      <p> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Sed hendrerit libero ac tellus posuere, a tristique nunc tincidunt. Sed et erat nec elit consectetur interdum ac ac eros. </p>
   </div>
</body>
</html>

The text-align property is a useful and powerful tool in CSS for controlling the alignment of text within an element. By using this attribute, you can make your web pages look more polished and professional.

Use to ensure metallic properties

The

CSS margin property can be used to center align an element within its parent container. This is accomplished by setting the left and right margins of the element to "auto".

When the left and right margins of an element are set to "auto", the browser will automatically calculate equal margins on both sides of the element, thus centering the element within its parent container.

Example

Here is an example of how to center align a div element using the margin attribute. In this example,

.center class defines the width and height, and the margin property is set to 0 auto. A div element is centered horizontally within its parent container. Add a background color to the div element for easier viewing.
It is important to note that in order for the margin: 0 auto technique to work, the element you want to center must have the specified width. If an element has no specified width, it will default to the full width of the parent container and will not be centered.
margin The margin property is a powerful tool in CSS for controlling the spacing and alignment of elements on a web page. By using this property, you can center align elements, create white space between elements, and control page layout.

<!DOCTYPE html>
<html>
<head>
   <style>
      .center {
         width: 300px;
         height: 200px;
         margin: 0 auto;
         background-color: #e5e5e5;
      }
   </style>
</head>
<body>
   <div class="center">
      <h1 id="Hello-World"> Hello, World! </h1>
      <p> This is a centered div element. </p>
   </div>
</body>
</html>

Using CSS Flexbox

Flexbox is a layout model in CSS that makes it easy to align and distribute elements within a container. It is a powerful layout tool in CSS that can be used to achieve many different layout effects, including center aligning elements.

It provides a flexible and responsive way to lay out elements on a web page, and can be used in conjunction with other layout techniques such as grids to create complex layouts.
We can use properties such as justify-content and align-items to center align elements within the container.

Example

Here is an example of how to center align a div element using Flexbox. In this example, the .container class is defined using the display: flex attribute, which makes it a Flexbox container.

The

justify-content and align-items properties are set to center to center child elements vertically and horizontally within the container. The .center class defines the width and height of the centered element and adds a background color for visual clarity.

<!DOCTYPE html>
<html>
<head>
   <style>
      .container {
         display: flex;
         justify-content: center;
         align-items: center;
         height: 100vh;
      }
      .center {
         width: 300px;
         height: 200px;
         background-color: #e5e5e5;
      }
   </style>
</head>
<body>
   <div class="container">
      <div class="center">
         <h1 id="Hello-World"> Hello, World! </h1>
         <p> This is a centered div element using Flexbox. </p>
      </div>
   </div>
</body>
</html>

Using CSS Grid

CSS Grid is a powerful layout system in CSS that makes it easy to create complex multi-column layouts. One of the benefits of using CSS Grid is that it makes center-aligning elements within a grid container a breeze.

Example

Here is an example of how to center align a div element using CSS Grid. Here, the .container class is defined using the display: grid property, which makes it a CSS grid container.

place-items property is set to center, which centers the child elements vertically and horizontally within the grid container. .center Class defines the width and height of the centered element and adds a background color for visual clarity.
CSS Grid is a flexible and powerful layout system in CSS that can be used to create a variety of layouts, including center-aligned elements. It provides a simple and intuitive way to create responsive dynamic layouts that can adapt to different screen sizes and device types.

<!DOCTYPE html>
<html>
<head>
   <style>
      .container {
         display: grid;
         height: 100vh;
         place-items: center;
      }
      .center {
         width: 300px;
         height: 200px;
         background-color: #e5e5e5;
      }
   </style>
</head>
<body>
   <div class="container">
      <div class="center">
         <h1 id="Hello-World">Hello, World!</h1>
         <p>This is a centered div element using CSS Grid.</p>
      </div>
   </div>
</body>
</html>
