Detailed explanation of how to use HTML <a> download attribute

As shown in the picture, I accessed it using Firefox browser and successfully downloaded and opened the image. I believe that if you test it yourself, you will already have an idea of the download attribute. The value of the a tag href here indicates the address of a file or image you want to download. The value of download indicates the name of the file or image you want to download and save.

But everyone should also note that the download attribute in HTML does not work in all browsers. Currently the a download attribute is only valid in Firefox and Google Chrome. The rest of the browsers such as IE, Safari, and Opera are useless.

To sum up, if you want to click to download a file or picture, you only need to master the usage of the download attribute in the a tag. If you only add the href file address to the a tag without download Attribute, then only the preview effect will appear and cannot be downloaded!
