It looked much better after I switched (in "bibel_2000.html")
Code:
<link href="bibeln.css" rel="stylesheet" type="text/css" />
<meta http-equiv="content-type" content="text/html" charset="ISO-8859-1" />
to
Code:
<link href="bibel_2000.css" rel="stylesheet" type="text/css" />
<meta http-equiv="content-type" content="text/html" charset="UTF-8" />
Spoiler:
css needs to be consistently renamed

char encoding seems to be just fine, it's just being declared wrongly as non-UFT-8.
Also, you have an unused style block in the header of the html. You could get rid of that... although it's pure code aesthetics.
Not bad... not bad at
all!
