The code of this theme has been written with localization in mind.
This means that you can create the default language files that WordPress uses (.po and .mo) and translate every text displayed by the theme without getting your hands dirty in the source code.
But let's take it even further
Introducing RTL text (right-to-left)
Maybe you're working on a site in Hebrew, or Arabic, or any other RTL language.
With this new version of Zerif Pro this is no issue. Just switch the language, and the theme will follow suit by changing the default display mode to RTL.
