When reading an epub on my XTEINK4 I noticed some of the text that should have been bold wasn’t.
Upon investigation of the underlying stylesheets of 2 epub’s I realized that in the working one font-weight was specified as bold vs the non-working one:
.class {
font-weight: 800;
}
To fix this I appended another rule to the stylesheet:
.class_a, .class_b ... , .class_z {
font-weight: bold;
}
I thought this might fix the issue but it didn’t seem like it.
