Ctrl-click for style not working

foosion · 09-08-2024, 02:47 PM

I have an epub with the CSS file directly in the OEBPS folder along with the xhtml files rather than in a separate Style folder.

Ctrl-click to open the first matching CSS style is not working - I get "no style rules that match the class xyz were found". The CSS file is linked correctly and everything else works properly (other than Live CSS).

Is this is a bug?

Fixing it in this ebook so that ctrl-click works would seem to require creating a Styles folder, moving the CSS file there and search/replace on all the links in the xhtml files. Or is there another way? Or I could just leave it, since the book can be viewed without issue, just editing is a touch harder.

Sometimes that happens. I've noticed two causes...

1. You have declearations at the top of the css file. Something like the following. For some reason, this interferes with the ctrl-click link which is a know issue in Calibre.
@charset "utf-8";
@namespace h "http://www.w3.org/1999/xhtml";

2. If you run the CheckBook and EpubCheck functions, there will be errors. One of those errors is breaking the ctrl-click link. Once the errors are fixed, it will work again.

1. The @ character does not appear in the CSS file. The CSS file looks normal to me, but I'm not highly experienced.

2. CheckBook says no problems found. I don't have EpubCheck installed, as it requires Java which I don't want to install.

It sounds like my guess about the CSS file not being in a Styles folder is incorrect.

The easiest way is to run "Arrange into folders" in the Tools menu.

Why are you hesitant installing Java?

Alas, using that to put the CSS file into a folder didn't help with ctrl-click.

FWIW, the CSS is Oxford University Press CSS version 1.2.

Java: I have a possibly irrational aversion to cluttering my computer with such files I rarely if ever use. Plus I'm not a fan of a language which forces you to put everything in a class.

I just edited another CSS file. It had @namespace epub "http://www.idpf.org/2007/ops"; at the top, but behaved normally.

Personally, I was more that happy to install Java to be able to run epubcheck in Sigil and in the calibre ebook-editor. I also check the CSS since it is kind of sad how often the CSS contains errors.

Impossible to say without access to the book in question.

Scrambled file attached.

The error is in your <head> tag...

<link href="OUP_Styles.css" rel="styleSheet" type="text/css"/>

"styleSheet" should be lowercase - "stylesheet"

Relink the pages to the stylesheet and it should be fixed.

Also, your <span class="chaptertitle">. There is no class for "chaptertitle" in the stylesheet.

That worked.

I'm surprised the CSS affected the text give the error in the link. Or, if viewers are forgiving, that the editor is not similarly forgiving (or noted the error).

You do need to install epubcheck and Javascript because calibre's error checker ignores some errors that epubcheck will catch. Either you install or you may have errors.

But you won't be rarely using Javascript because you'll be using it with epubcheck.

I always do a fresh link to the CSS as a lot of the time, the cover and titlepage HTML are not linked. So it's just easier to do it and not have to look.

There's a script reference in the navigation.xhtml file:

Code:

<script xmlns="http://www.w3.org/1999/xhtml" type="text/javascript"></script>

Why would that be there?
