I've just started with all this website building stuff and now I'm stuck.
I'm struggling with a function that I cannot get to work. The thing is actually pretty simple, but I am out of ideas and so is Google.
What I want to do is: when the 'Login' button is clicked, there should appear an extension under the button, where users can fill in their log-in information.
Since I am a total beginner, I tried to work it out from a bit of code from W3Schools' website. Unfortunately, it didn't work, but anyway: here is what I have got at the moment.
I also tried to insert <form> right into "innerHTML="here";".
I'm sorry for being a total newbie, but I feel like I can't continue if this thing remains a mistery for me. So, please don't judge me too hard.
I will provide some pictures:
