Invisible text

[DaleDe]

I have an eBook that includes the physical page numbers from the paper book. I would like to leave these in the document for possible use in searching or referencing purposes but I don't want them to be displayed. Is there a way to do that? The book has a lot of cross references to physical pages.

You can use style="visibility:hidden;", eg.:

<span style="visibility:hidden;">1</span>

or "display: none"

Could you use a class?

e.g.

<span class="invisible">..</span>

and in your CSS

.invisible { 
  display: none; 
}

Hard-coding styles into HTML or XHTML or XML is really ugly.

Actually "display: none" seems to be the better choice, because it shouldn't occupy visible space - which does happen when using "visibility: hidden".

Sure, but imho it's better comprehensible with a inline style within a simple example.

It is But I still wanted to add this as (so far) I've nearly always found inline examples on this board, and just once I wanted to say "use classes"

they're classier.

Thanks for the response. I will give it a try. I know how to translate inline examples to CSS sections and files.

When I retrieve a Project Gutenberg ebook in HTML form, I usually leave the page number (href) references in, but remove the actual PG #'s using a RegEx, like the below example written in Perl:

#Remove page numbering
$html =~ s#<span class='pagenum'><(.*[^>])>.*</span>#<$1>#gi ;
$html =~ s#<span class=\"pagenum\"><(.*[^>])>.*</span>#<$1>#gi ;

It just leaves the <a name/id> reference i.e. <$1>.

Yea, but I have hundreds of such references and no html links. For now I want to be able to have the real page numbers. The display:none trick worked well in my sample. I have to check a few different readers. It is reasonable to have the published page numbers for reference purposes.

And that makes "visibility:hidden" what I was looking for for some other cases. Sometimes the detective finds a half-burnt note with some letters missing, and it's good to have something that hides the letters but preserves the space
