I have finished a set of buttons with hover effects. It is going to be inserted into an existing website. I want the client to experience and approve the set before I post it to his page. Can I share the interactive preview in the browser somehow? He does not have CC.
No they are your local files you will have to upload them to a server in order for him to see them or simply take a video of you playing around with the buttons and send him that.
As RavenDesign mentons, simply File > Publish > Web, then upload the published folder to a folder on an external host.
