How to display HTML in the center
In web design, centered display is a very common layout method. For HTML page developers, how to center elements is an essential skill. In this article, we’ll look at some ways to center HTML.
1. Text Centering
For text in HTML pages, you can easily center it using CSS. For example, add the following code to your CSS file:
text-align: center;
This code will center all text in the element.
2. Block-level elements are centered
Block-level elements refer to DIV, P, H1 and other elements. To center these elements, we can use the margin property. The following code will center the DIV element horizontally:
div { margin: 0 auto; }
This will give equal spacing to the left and right sides of the DIV element and center the element horizontally.
3. Center the image
Centering the image is also a skill that developers need to use. We can center the image using the text-align attribute by writing the following code in HTML:
<div style="text-align:center;"> <img src="img/logo.jpg" alt="Logo"> </div>
The above code places the image and its description in a DIV and centers the DIV. You can control the size of the image by setting the width and height of the DIV.
4. Table centering
If you need to center the table in the HTML page, you can use the margin and text-align attributes. The following code shows how to center the table:
table { margin: 0 auto; text-align: center; }
This code centers the table horizontally and centers the data in the table in the columns.
5. Centered display of fixed-width elements
When we need to center a fixed-width element, we can use the following CSS code:
.element { position: absolute; left: 50%; margin-left: -[元素宽度的一半]; }
This will make the element relative to the parent element Set the distance to the left to 50% and move it half the width of the element to the left to center it.
6. Flexbox layout
Finally, we can also use flexbox layout to achieve centered display. Flexbox is a fluid layout that optimizes the way elements are arranged on the page. Here is an example:
.container { display: flex; justify-content: center; align-items: center; }
Add the above code to a container in an HTML file to center the content in the container.
Summary
Centered display is one of the basic techniques in HTML page design. Whether it’s text, images, tables, or fixed-width elements, you can use different techniques to achieve centering. When developers master these techniques, they will be more comfortable creating beautiful, eye-catching pages.
