Add HTML design to ASP.NET project

<div class="post-text" itemprop="text"> I created an HTML design. Now I want to use that design in ASP.NET project. Is there a way to add all HTML pages and turn them into aspx pages with code behind for every page? I can just create an empty Web Form and copy the content of all my HTML pages one by one. But is there an easier way? I want to use Web Forms not MVC.

</div>
