Hi all. I've just noticed something for the first time today. In some content that was in draft mode and not published, I pulled a CSS selector of a button to use in the theme CSS.
Normally the selector would be of this form:
#edit-submitted-cv-upload-button
But when I put it in the CSS I noticed that it had '--2' appended to the end, like this:
#edit-submitted-cv-upload-button--2
Then when the page was published the selector was, as expected, #edit-submitted-cv-upload-button, but as also expected now the CSS was broken.
