What is the difference between src and href? Find out quickly!

In the process of web development, src and href are two commonly used attributes. Although they look similar, they actually have different uses and applicable scenarios. In this article, we’ll dive into the differences between src and href and explain them with concrete code examples.

In HTML, src is an attribute used to specify external resources to be embedded or referenced. It is usually used to reference images, audio, video or script files. Unlike this, href is an attribute of a hyperlink that specifies the target of the link. This can be a website, a document, or an anchor.

Let’s take a look at the src attribute first. Let's say we have an image file called "image.png" and want to display it on a web page. We can use the following code:

<img src="/static/imghw/default1.png"  data-src="image.png"  class="lazy" alt="My Image">

In this example, the src attribute specifies the path to the image file to be embedded in the web page. The browser will parse this path, find the corresponding image file, and display it on the web page. Note that the src attribute is required, without it the image will not be displayed.

Next, let’s take a look at the href attribute. Let's say we want to create a hyperlink that will navigate the user to another web page. We can use the following code:

<a href="https://www.example.com">Visit Example</a>

In this example, the href attribute specifies the target URL of the link. When the user clicks this link, the browser will jump to the specified URL. Also note that the href attribute is required, the link will not work without it.

Another common usage is to use href for anchor links. Let's say we have a long web page and want to scroll the user to a specific part of the page. We can use the following code:

<a href="#section1">Go to Section 1</a>
...
<h1 id="Section">Section 1</h1>

In this example, the href attribute specifies the id of the target anchor point to scroll to. When the user clicks on the link, the browser scrolls to the element with the corresponding id, which is the "h1" tag.

It should be noted that the values ​​of src and href attributes can be relative paths or absolute paths. If relative paths are specified, they will be resolved relative to the location of the current web page. If absolute paths are specified, they will be resolved relative to the server's location. This is also an important difference between them.

Before concluding this article, we once again emphasize the main difference between src and href. src is used to embed or reference external resources, such as images, audio, video or script files. href is used to create hyperlinks, used to link to other web pages or establish anchor links.

I hope this article can help you better understand the difference between src and href and use them correctly in web development. Through specific code examples, we explain their uses and applicable scenarios in detail. Now you should be able to use these two properties accurately for external resources and hyperlinks!
