Create Free Website With Your Domain Name in Odoo

Is there Any possible to add css in this Web page?

We can put own domain name ??

I used the website app for my project but when it's time to present my website is gone it's just a trial it say the data last just for 4 hours

what if I want to use my own domain (e.g. www.mydomain.com) ?

Is it just free forever or it's only a trial version? Need some clarifications please!

On Ubuntu and Lets Encrypt?
