Href stops working when the site is deployed

Website id:

I wanna start by saying that i’m still a beginner, i have an undertanding of html and css, completely blank on js.

So i made a little artistic project, very simple pages with little code inside

Locally the website works perfectly, but once i deployed the website every anchor stopped working and links aren’t clickable anymore.

i doublechecked every file name and made sure no capitals are around and no spaces in file name.

I’ve read some material online (of which i understood probably around 30%) and in my code i have no rules to convert html file, no redirects, not that i would know how to write any of that.

Could someone explain in simple terms how should i proceed or educate myself about please?

Not without a working link to look at.
