I. Introduction
A. Definition of the HTML anchor tag
The HTML anchor tag is used to create hyperlinks. It connects web pages, sections of pages, or external resources. The basic syntax of an anchor tag is as follows:
<a href="URL">Link Text</a>B. Purpose of the download attribute
The download attribute in an anchor tag instructs the browser to download the linked file rather than navigating to it. When a user clicks a link with the download attribute, it tells the browser to initiate a download and saves the linked resource locally.
II. The download Attribute
A. General syntax
The syntax for using the download attribute in an anchor tag is straightforward. Here’s the basic structure:
<a href="file_url" download>Download File</a>B. Values for the download attribute
The download attribute can accept a value, which specifies the filename that will be given to the downloaded file. If no value is specified, the original filename of the resource will be used.
<a href="file_url" download="custom_filename.ext">Download File</a>| Attribute Value | Description |
|---|---|
| No Value | Uses the original filename of the resource. |
| Custom Filename | Uses specified custom name for the file. |
