src and href are two common attributes in HTML, used to reference external resources. They have the following main differences:

Different uses:

src (source) is used to specify external resources to be embedded into HTML documents, such as images, audio, videos or JavaScript file.

href (hypertext reference) is used to specify links to resources outside the HTML document, such as CSS style sheets, font files, or other web pages.

Different reference methods:

The resource referenced by the src attribute is required and will occupy a certain space in the document, directly affecting the rendering of the document. For example, will embed an image in the document.

The resource referenced by the href attribute is optional and does not occupy the space of the document. It is only used to specify links to resources outside the document. For example, will link to a CSS style sheet file.

src attribute embeds the referenced resource into the document and therefore directly affects the loading and rendering of the document. If the resource referenced by the src attribute cannot be loaded or is incorrect, the embedded content will not be displayed or run.

The href attribute does not directly affect the loading and rendering of the document, but affects the style and behavior of the document by linking to external resources. If the resource referenced by the href attribute cannot be loaded or is incorrect, it will only affect the use of the resource, but not the display of the entire document.

Different scopes of application:

The src attribute is suitable for referencing resources such as images, audio, videos, and scripts. For example, is used to reference image resources, and is used to reference JavaScript script files.

The href attribute applies to CSS style sheets, font files, and links to other web pages. For example, is used to link to a CSS style sheet file, Link is used to create a Hyperlinks to other web pages.
