Hi hope you can help,
I'm trying o edit the size of the H1, H2, etc. in he style.css file. But when I click on the save buton, all text dissapears and the blog looses all formatting.
I've tried copying and pasting the text from the file I downloaded directly and clicking on the save button, but nothing happens, the file remains blank.
I had to delete the theme from the blog and re-install it.
