Can h5 page add music to a single page?

Why not? It is very simple to make it with Epub360 H5 tool.

I suggest you try this:

? Open Epub360 H5 editor; Select any page, select "Audio" in the toolbar above and "Music" below, and click Upload.

Please click to enter a picture description.

This advantage: high flexibility, almost can meet most of the needs.

Precautions:

1. Pay attention to editing and making with Google browser;

2. Choose audio upload instead of background music upload;

3. The audio file format needs to be mp3, because it must conform to the protocol of html specification.
