Calibre converts lower to uppercase

[Gareth Thomas]

When using Jutoh to format my ebooks chapter headings are in lowercase: "Chapter". When I import them and convert them from EPUB to a AZW3 format Calibre converts the lowercase into uppercase: "CHAPTER".

I then have to DELETE this line of code from the CSS for the heading to revert back to lowercase: text-transform: uppercase;

When this file is converted from EPUB to AZW3 in Calibre lowercase is converted to upper case.

I have since noticed that the title and the chapter headings are also converted from lowercase to UPPERCASE when converted from EPUB to AZW3. This necessitates having to manually remove this line in the CSS "text-transform: uppercase;" in order for the UPPERCASE to be converted back to lowercase.

This is because in your CSS stylesheet you have two rules:

.P_Chapter {
font-weight: bold;
font-style: normal;
font-size: 1.50em;
text-align: center;
margin-top: 0.00em;
margin-bottom: 5.00em;
margin-left: 0.00em;
margin-right: 0.00em;
text-indent: 0.00em;
}

.P_CHAPTER {
font-weight: bold;
font-style: normal;
font-size: 1.50em;
text-transform: uppercase;
text-align: center;
margin-top: 0.00em;
margin-bottom: 5.00em;
margin-left: 0.00em;
margin-right: 0.00em;
text-indent: 0.00em;
}

See the text-transform: uppercase in the second rule. When converting,
calibre matches class names case-insensitively, as that is what the vast
majority of documents use. Therefore, the two rules get combined leading
to what you see. In general you should never have CSS rules with
different cases for the selectors as that will lead to lots of problems
in lots of places.
