I'm sorry it took me so long to see this! Thank you so much!! And yes, if you haven't already found an answer for this, it's totally possible with Twine's tagging system. I'm actually working on this in another template I'll be sharing hopefully soon, but I'm happy to go over how to do it here too<3
First, you're going to add a tag to the passage you want the header hidden. In this example, I'm using the tag 'start':
Then you'll go into your Stylesheet and add:
.start .header {
display: none;
}
And you'll end up with this:
No header! Hopefully this helps:) Happy coding and I can't wait to see what you come up with!
