What is the difference between src attribute and href attribute in how their purpose and function are different?

The src attribute and href attribute are commonly used attributes in HTML and are used to specify the path or link to external resources. Although these two properties have similarities in appearance, there are clear functional differences.

First of all, the src attribute (abbreviation of source) is used to specify the path of external resources, usually used to embed external scripts, images or audio and video files into HTML documents. The value of the src attribute can be a relative path or an absolute path.

Take images as an example. If you want to insert a picture into an HTML page, you can use the following code example:

<img src="example.jpg" alt="Example Image">

In this example, the value of the src attribute is "example.jpg" , which specifies the path of the image to be inserted. The browser will load the corresponding image according to the path and display it in the HTML page.

Let’s look at the href attribute (abbreviation of hypertext reference), which is mainly used to specify the link relationship between referenced documents. The href attribute is commonly used in HTML anchor links, navigation links, style sheet links, etc.

Taking the anchor link as an example, you can use the following code example:

<a href="#section1">Go to Section 1</a>

...

<h2 id="section1">Section 1</h2>

In this example, the value of the href attribute is "#section1", which specifies that the target of the link is the id The element of "section1". When the user clicks on the link, the browser scrolls to the appropriate location so that the target element is visible.

In addition to anchor links, the href attribute can also be used for navigation links, such as jumping to other web pages:

<a href="https://example.com">Go to Example Site</a>

In this example, the value of the href attribute is "https://example .com", which specifies the web page to which the link will jump.

It should be noted that the purposes and functions of the src attribute and the href attribute are different. The src attribute is used to embed external resources into HTML documents, and the href attribute is used to specify link relationships. In practical applications, using these two attributes correctly as needed can improve the performance and functionality of web pages.

Finally, when using the src attribute and href attribute, you need to fill in the value of the path or link correctly. Relative paths are resolved relative to the path of the current document, while absolute paths are the full path starting from the root directory. Therefore, pay attention to the accuracy of the path when writing code to ensure that external resources can be loaded or linked to correctly.
