There are no standards that apply here.
As of Windows Internet Explorer 9, this method is supported only for webpages displayed in IE5 (Quirks) mode. For webpages displayed in standards mode (preferred), use the IHTMLElement2::scrollLeft and IHTMLElement2::scrollTop properties.
The IHTMLElement2::doScroll method is available on all objects, regardless of whether they support scrollbars.
Cascading Style Sheets (CSS) allow you to scroll on all objects through the IHTMLRuleStyle::overflow property.
When the content of an element changes and causes scroll bars to display, the IHTMLElement2::doScroll method might not work correctly immediately following the content update. When this happens, you can use the IHTMLWindow2::setTimeout method to enable the browser to recognize the dynamic changes that affect scrolling.
