Possibly there is any way taking a print screen of the whole webpage, rather than what is just around the screen
In case you were on a Mac you may do a Screen-print Preview, save it for a PDF, and then play by using it in Photoshop. Otherwise you must just take specific screenshots and stitch these people together (what I do).
ok when there is no way to complete that is there a way to get the height of the webpage
None we know of.
windowpane. innerHeight and windowpane. clientHeight i trust.
