How to fold any text as I want?

How to fold any text as I want?

[Magicloud Magiclouds]

Dear,
    Now emacs provides outline and hs modes for folding, I think. But 
they both need some "text hint" to do the hide/show. May I do the 
hide/show by line number? Like "M-x hs-hide-ln 10, 20".

Thanks.

I can't speak for hs, which I don't know.  But for outline-mode, folding
is done along the *structure* of the document.  So it doesn't make sense
to fold according to a range of lines.  Actually, I think this would be
quite confusing... How would you know what lines are folded ?

Take a look at hide-region.el. It lets you hide regions of text:
