My class diagram cannot be displayed. about type-on-strap

Could be the version of mermaid, I'll update it

The issue is the <<interface>> the < does not work well in HTML, so you can either try to escape it or use:

  <div class="mermaid" id="1">
  classDiagram
      Print <-- Main:Uses
      Print <|.. PrintBanner
      Banner <|-- PrintBanner
      class Main
      interface Print
        Print: printWeak()
      class PrintBanner{
        printWeak()
        printStrong()
      }
      class Banner {
       showWithParen()
       showWithAster()
      }
  </div>

And it should work
