How to create and set div styles in html

In web design, div is a very common element. It can be used for various functions such as grouping, layout and style control. Therefore, it is very important to learn how to set up divs correctly. In this article, I will teach you how to set up divs using HTML.

1. What is div

A div is a container element in HTML that can be used to wrap other HTML elements. Its full name is "division", which can be translated into Chinese as "block" or "partition". The div element is more flexible and can be used to divide web page layouts or wrap various elements.

Usually we use div to set CSS styles, because the div element will not affect the effect of text and other tags. In web design, the page is generally constructed according to the modular design idea, and different parts of the page are surrounded by divs, which facilitates management and maintenance.

2. How to set up a div

1. Create a div element

To create a div element, use the following HTML code:

<div></div>

Here, the div element is placed in the direct child element of the tag. When you open the HTML file in the browser, you will see that nothing is displayed on the screen because the div element itself does not have any special display effects.

2. Set the style of div elements

You can set the style of div elements through CSS, for example:

div {
  width: 500px;
  height: 300px;
  background-color: #fff;
}

This CSS code will make div The element has a width of 500 pixels, a height of 300 pixels, and a background color of white. You can also set the borders, padding, and margins of the div element as needed.

3. Put elements inside div elements

You can further control the layout of your page by placing other HTML elements inside div elements. For example:

<div>
  <h1 id="这是标题">这是标题</h1>
  <p>这是一段文本</p>
</div>

This code will cause the title and text to be included in the same div element. At this time, CSS styles will be more flexible, and the styles of each element can be adjusted as needed.

4. Split pages

In addition, the div element can also be used to split pages. For example, the following code can be used to divide the page into different parts:

<div>头部</div>
<div>主体</div>
<div>尾部</div>

You can control the style of each divided part through CSS styles. Web pages created in this way are composed of multiple div elements. This method is very flexible and easy to maintain.

In general, the div element is very important in HTML. It can be used for various functions such as page layout, style, and segmentation. By using the div element correctly, you can build a web page with a beautiful interface, clear structure, and easy maintenance.
