I'd really like to find some fonts which appear to be on a tape, but not embossed like Dymo.

Something simple, like a Helvetica font, but on a solid black background. And not embossed!

Does anybody know of one?

Does anybody know what such fonts are called?

Thanks.

Something like Blackout?

Kind of... it's too much of a 'style', I'm really after something very plain and simple (for web use by the way).

If you only want to use this black background style for a website, it's going to be much easier to use CSS to do that background honestly. Plus you get to use any font you like in the first place.

Thanks for that... how easy is it to do that? I am just an amateur and built my site using zero-coding Blocsapp.

It depends how much you already know but it's honestly not that hard. You should try to learn a little bit about CSS and properties like "background-color" (for the background of your text) or "color" (for your text).

Edit: I don't know much about Blocsapp but it seems like something you can easily achieve without even knowing CSS.
