How can I specify container's width?

[Rivershot]

Hello, Thank you for your good js

I tried to make my own project using wavesurfer
but I can't understand how can i specify width...

I read Api document and saw setHeight method So I can specify that
but setWidth was not work...

Can you explain how I specify width..?

You can set the width on your container div via CSS.
