SoftScroll.
Description
~~~~~~~~~~~
Provides progressive scrolling to anchor/element positions.
Provides a direct replacement for the window.scrollTo function.

These instructions may be removed but not the above text.
Please notify any suspected errors in this text or code, however minor.
Installation
~~~~~~~~~~~~
Save this text/file as 'softscroll.js', and place it in a folder associated with your web pages.
Insert the following tags in the section of the document to be scrolled:
(If softscroll.js resides in a different folder, include the relative path)
Configuration
~~~~~~~~~~~~~
For normal operation no further configuration is required.
To scroll the page to an initial anchor when it loads, insert the following code anywhere below
the installation
If you wish the target anchor to be displayed in the address bar once the scroll is completed,
add this code below the script configuration:
Please note that in some circumstances this may cause a slight jump at the end of the scroll.
Notes for correct operation
---------------------------
If any involved links have an onclick handler, the handler must return false, i.e:
All anchors should have at least one non-whitespace character between their tags, e.g.:
The ID of an element may be specified as an anchor, and NAME attributes may be specified for
scrolling to form elements.
If the document uses any other scripts that use the onload event, they should be loaded prior to softScroll and not initialised inside the tag.
Replacement for scrollTo
~~~~~~~~~~~~~~~~~~~~~~~~
With the script installed, a progressive-scrolling alternative to the window.scrollTo function is available.
Call: SoftScroll.scrollTo(x, y);
