no code between tags

I can't put any code between the


header> tags. Is this a bug or how can I do this?

What code are you trying to add? If you're trying to add classes and ID's and other attributes I would suggest you watch and read the tutorials available to get the main idea of how the app works.

Thank you Jo, it was a mistake from me. I tried to put the header-component in to the html-code, but I have to put it in to the overview.

Ahh I see, yes you can drag the components to either the Overview pane or into the Preview window itself to add new components. Glad you worked it out, enjoy!
