Notes

Purpose of the mod

This mod was developed to scroll pages and charts with overflowing content.
(Thanks to Darrin and Ken for functionality suggestions)

Charts cannot be scrolled horizontally in TNG v13 or v14. Instead of an update, the Scroll Mod was created for vertical scrolling.

Developer

This mod was developed by Steven Davis

Advantages

This mod places four scroll buttons in v13 and up to six scroll buttons in v12 at the lower right side of the display.
Scroll to the top, up, left, right, down and bottom of the page.
Buttons do not appear unless content overflows.
Scrolls Ahnentafel and Register pages.
Adjust the scroll height when scrolling up and down or compensate for a sticky header.
Loads with the inner menu so buttons do not appear on mobile devices.
If a template uses the scroll to top button, it will be hidden when scroll xy buttons are shown.
Includes a scroll-config.php file to control which pages display scroll buttons.
Includes an example scrollpage-info.css file to customize the buttons using mytngstyle.css.
The mod can be used with v12.1.0 through v13. With horizontal scroll exceptions for v13.0 charts.
For those that use Scrollbox_mod, scroll buttons are not shown on any pages where that mod is used.

TNG v12 and v13

Scrolls all pages and charts in TNG v12.0 though v12.3 versions.
Scrolls all pages but does not scroll charts horizontally in TNG v13 due to the new drag feature.
Scrolls all TNG v13 pages and chart pages with overflow vertically.
Since the new charts use a body div with nested outer and inner divs, Scrollx-y cannot scroll nested divs.
Horizontal scroll buttons will not appear on charts that cannot be scrolled.

Appearance

When the mod is first installed, refresh the page to reload the style sheets.
Scroll buttons appear at the lower right but can be moved using css.
Scrolls pages with overflow including person, register, text and chart pages.
Examples to change the buttons are in the scrollpage-info.css file.
