  the same for the text of the names of the categories, the text of this button, is in capital letters,  «RELATED POSTS» also ..

that is, it might be easier to make a code in which everything that the theme changes to capital letters, can automatically be passed lowercase?

Thank you very much for the support, and congratulations for the theme is very modern and functional.
