I wanted to change the font size in the regular text of my pages in my twenty twelve and I went into the css-file and tried a little and something went wrong. (I did make a backup in a open office file).
What happens now is that the size of the fonts can't be the same size as they were earlier. The fonts are either bigger or smaller than how they were before. I've searched the code and comapared it to my backup but I can't find what's wrong. I also used a different tool - which shows whats differs between two codes - but the program couldn't find anything that differs.
I also noticed that if I write a new article the fonts are ok but if I try to formate (change) the fonts then they becamo to small or to big and not like the original font size before the formation.
The page are in swedish. As you see the text isn't a disaster but there is a difference.
