add tag
I'm learning html by myself. To create my first webpage, I decided to use Chrome... (only very recently have I discovered Notepad ++).

When I'm in Chrome, and I add an iframe preview of pdf file, all works fine, until I want to save it.

Here's a MWE.

        <title>Title of the document</title>
        <h1>Here's a preview</h1>
        <iframe src="../path_to_parent_folder/file.pdf" width="100%" height="500px">

When I try to save the page, using ctrl+s, I get the normal Chrome saving icon,

(démarrage = start), but it never ends... it keeps endlessly trying to save, without ever finishing. And if I suspend/annul the saving process, the original file will have been deleted.

Why is that?
