Scroll in the HTML file without scrolling bars

Question

I have a HTML file with javascript, which adds to the mouse wheel zoom function (instead of scroll).

Scroll bars aren't displayed and moving up-down-right-left is only through drag-and-drop with the mouse possible.

PageUp and PageDown don't work too.

Trying to screenshot makes screenshot of area only visible in the browser window - not from the whole page content.

My question is: how is it possible,

• at least, to scroll down with PageDown (to make consecutive screenshots),
• or, in the best case, to save the whole page (not only the area visible in browser) as image/pdf.

Answer 1

Sorry, but from what I know there is no easy way to do this. Unless you are skilled enough to use Developer Tools (F12) in your browser.

For example in Google Chrome:

1. right click on the area you want to make a picture of
2. select "Inspect"

3. in Styles pane on the right side you may try adding following CSS styles, which should give you ability to hopefully scroll the page:

   • overflow
   • width
   • height

see this DevTools screenshot

For example:

element.style {
    overflow: visible;
    width: 2000px;
    height: 2000px;
}

You might need to play a bit with the values, and/or other CSS styles if necessary. Since you did not provide the exact URL for the page in question, I am giving here just a generic answer.
