If you create a textbox, where people can put HTML tags and on form post you take it into an variable and load it into a Label, it will be rendered by the browser.

lblHtmlRenderer.text = txtTextBox.Text

But you need to be careful as people might post malicious code (cross-side attacks) into your site which would be harmful.

Also you would need to add ValidateRequest="false" in ur <% Page tag (this is also not too good idea).
