I am new to both Calibre and CSS but managed to follow the directions from this thread
http://www.mobileread.mobi/forums/sh...ad.php?t=80790.
I tried many times to alter the default text (i.e. CSS body tag) color of an ebook document (specifically and perhaps ironically a "For Dummies" ebook) and tried to apply the CSS stylesheets that users in this thread posted with no success even after converting the book with Calibre's converter to various formats.
I stripped out a few things which in the end I haven't missed. I noticed that calibre assigns its own moniker to the various custom CSS classes in the master stylesheet (i.e. ".Calibre17") and each has its own attributes. What a PITA this process was to figure out for a newbie...
I removed these attributes and their respective settings from all ".CalibreX" instances: "color: xxxx", "background-color: xxxx", and "display: block". For some reason I removed the last one on a whim. I have no clue what it did. Thanks.
