Anyone has an idea how I can change the domain name using CNAME?

Buy a domain
Add a cname record

If your domain register doesn't offer cname records, direct it to cloud flare then cname it.

Enjoy.

@C0D4 are there really domain hosters that cannot make a cname?

@stop yep.
Usually the cheaper the host, the less it offers.
I've seen dodgy ones that had NS records as the only option.
Everything else I had to handle though CF or on the host it's self.

You put HTML/CSS at 90%? I'd give you maybe 30%.

Some 4 MB bloated piece of crap that doesn't even validate and loads so slowly that some loading animation garbage is there, insane 400k of CSS and 1 MB of JS, no logical document structure as seen in the completely fucked up heading levels, tons of contrast errors that make the resume unreadable, missing form labels and a host of other issues.

@Fast-Nop wait... did you click the link? Ooh now I want to see what I didn't look at.

I shouldn't have done that, I really shouldn't have done that, but Wow that's a lot of pink at the bottom.

Additionally, you might want to reread for typos.
And optimize loading, a static Website with >10 sekubds load time over WiFi (haven't even tested mobile data) is just to slow.

The loading indicator doesn't even work properly. Why is it spinning around itself?!
