When I add a link to text in a text box, the size of the font reduces significantly and I cannot change it back. Can you help?

I set my font size some time ago, but some how with changes my linked font size is smaller than the rest in a post for example. I have tried changing it numerous times but it still seems to not budge....

Hello how can I link from the theme frontpage (text and pictures) to various pages ? Thanks a lot ! Best regards Beat
