Editing html to replace non textbox words

Site URL: http://www.pimpirim.lt/

Hi,

I recently began developing a website with squarespace but ran into an issue. The language of the country I am palling to retail in is not supported. The entire website is in Lithuanian but some elements remain in English, such as: add to cart, select, checkout and so on. Is there a way to edit the html code and replace these with words of my choosing?

Hi. You can translate all, except checkout page (/checkout) :(
