Thank you, I have tried again and also changed the style.css.
I now see the larger font on this page: http://www.dietzcoaching.nl/weblog/ (the blog page overview with short introductions to every blog), that’s great. But when I open a single blog (like this one http://www.dietzcoaching.nl/is-baas-huis-grenzen-aangeven/), the font is still small. Is it possible to enlarge the font in each single blog?
I’m sorry for asking all these questions, I’m really happy with your help!
Kind regards,
Mariette
