[mufc]

I have great success creating my own or modifying other recipes for best readability of my sony ereader. One thing I wanted to do and did was remove the hyperlink properties using
a {text-decoration: none; color: black;}
a [href] {text-decoration: none; color: black;}
I have tried but failed to remove the highlight background from the hyperlinks.
They highlighted background does not show up when reading in Calibre but does when reading on my ereader. Am I correct in assuming that I need to change something in the css of epub output ? If so where is this file and what is it called ?
Thanks
