Translate static home page

Hello,
I have “Portum” theme installed on my web page and I am wondering how can I translate static web page which contains a lot of different sections.
For example services, contact, news and lot of other sections.
If I translate a home page and switch on another language (not default) it is changing but a home page becomes to an usual page.
Is there any possible ways to translate static home page with same visual as it is?
