I've just tested it and it's a shame that with
Preference > Look & Feel > Book detail and by editing the custom CSS with:
Code:
table.fields td.title
{
text-align: left !important;
color: black !important;
font-style: normal !important;
font-weight: bold !important;
}
you can't bring back the old style.
A like the new, but that a flaw in the customization.
A use the !important and still not work, so no idea to overide this.
