On Click Elements in a Single Page App - Buttons, Links or Paragraphs?

So I’m creating a single page app.

There are a gzillion things my users can click on to make things happen. Some appear as text, some as icons, and some as buttons.

But since it is a single page, their clicks never result in taking them to another page. I’m just doing on Click Dynamic Events or Form Submission to make something happen.

So I’m sitting here wondering what the clickable elements should be which aren’t doing form submissions…

• Links with href="#"?
• Paragraphs?
• Buttons styled as text?
• Something else I didn’t think of?

I’d love to hear your views on the pros and cons!

Best wishes,
Antony.
