Responsive html5 to aspx

Dear,

I'm using Framemaker 2019 to develop and maintain a web enabled user manual for my client in biopharma.

The responsive html5 application is a beautiful tool, with great navigation functionalities over hundreds of topics.

Recently the company decided to only allow aspx on the sharepoint servers.

Is there the possibility to generate aspx directly or to transform it later on from the html5?

Looking forward for your advice or experiences.

Hugo
