Either way, the editor opens and displays two side-by-side panes — both initially blank — although the right-hand pane displays an option to " Run check."
When I run a check, the left-hand pane immediately fills up with a long list of error messages ("Invalid ID," "xyz...does not exist," "Unexpected empty block," etc).
Simultaneously, a brief list (summary?) of error messages appears in the right-hand pane, along with the option to "Try to correct all correctable errors automatically." Without knowing what I'm doing, I'd sooner not risk it.
I've run this check on half a dozen books, and get a similar blizzard of error messages every time.
With that said, I've had no trouble opening or reading books in Calibre. Was happily unaware of any chaos behind the scenes until today. And if undoing the mess is too complicated, I may not bother. Not being able to change a book cover is, let's face it, small 'taters! 
Cheers, and thanks again. |
The calibre viewer is closer in design to a web browser and will do a decent job of handling garbage input. Many ereaders will not handle them so garbage in gives you garbage out.
My personal preference is to correct any errors before the ebook moves from my Intake library to my Main library. With either the calibre ebook editor or Sigil, I use the Epubcheck plugin and an ePub is not ready to go until Epubcheck reports no errors. Part of this is that I do some cleanup on other peoples' ebook so they can submit them without their ebook being bounced for errors. For many publishers, Epubcheck is their standard error checker.
Once you start editing the CSS and text/html files, you fairly rapidly learn what is and is not acceptable. I will admit some of the discussions in various threads get rather fervent since many of us have rather strong opinions on how an ePub, it's html and stylesheets should be managed.
Just do a backup of your original file to make it easy to revert your changes if the fan gets hit.
