What does the HTML box model structure include? Need specific code examples

The HTML box model is one of the important concepts in web page layout. It describes how web page elements are rendered and interact with each other in the browser. The box model consists of four main components: content area, padding, borders, and margins. This article will detail the meaning of these four parts and provide specific code examples.

1. Content area (content)
   The content area refers to the area where elements are actually displayed, including text, images, nested elements, etc. Its size is determined by the element's width and height properties.

Sample code:

<div style="width: 200px; height: 100px; background-color: blue;">
  这是一个内容区域示例
</div>

2. Padding
   Padding refers to the spacing between the element content and the border, used to control the content and The distance between borders. It can be set using the padding attribute.

Sample code:

<div style="width: 200px; height: 100px; background-color: blue; padding: 20px;">
  这是一个带有内边距的示例
</div>

3. Border (border)
   A border is a line or image that surrounds content and padding. It can be set using the border attribute, including color, style, width, etc. Common border styles include solid, dashed, double, etc.

Sample code:

<div style="width: 200px; height: 100px; background-color: blue; padding: 20px; border: 2px solid red;">
  这是一个带有边框的示例
</div>

4. Margin (margin)
   Margin refers to the space between an element and other elements. It can be set using the margin attribute to control the distance between elements. Unlike padding, margins do not affect the background color of elements, only the spacing between elements.

Sample code:

<div style="width: 200px; height: 100px; background-color: blue; padding: 20px; border: 2px solid red; margin: 10px;">
  这是一个带有外边距的示例
</div>
