audio clip with animated gif for website

I have an animated gif and an MP3 file that I want to combine and add as a link to a website page. Ideally, the image will be hidden until an icon is clicked, and then the animated gif fades in while the MP3 starts to play. Upon the end of the audio, either the gif can fade out or we can add a menu item that says "close" or something. The mp3 is about 1 minute long.
