Cross-Platform Functionality

With Internet Explorer 4.0, content authors can easily create pages that run on all platforms—the 32-bit Windows® platforms, Windows 3.1, Macintosh, and Unix. In particular, core Dynamic HTML (DHTML) and Active Channel functionality are cross-platform.

The following DHTML features are supported across platforms.

Full CSS 1 Core
CSS–Positioning
DHTML–Dynamic Styles
DHTML–Stylesheet Object Model
DHTML–Element Collection
DHTML–Event Model
DHTML–Core Dynamic Content: innerHTML, outerHTML, and associated methods
Data Binding
HTML 4 support
HTML dialogs

The following Active Channel functionality is supported across platforms.

General CDF support
Subscriptions, notification, offline reading

In addition, several features are available on some platforms but will degrade gracefully on other platforms.

CSS Filters and Transitions. On some platforms, the filters and transitions may degrade to a basic filter or transition effect.
Font Download. If a platform does not support font download, another font already on the computer will be substituted for the specified font.
User Profile–Object Model. If a platform does not support this feature, it will appear as though the user has disabled it.

Win32 Premium Platforms

In addition to the cross-platform functionality, the versions of Internet Explorer 4.0 for the 32-bit Windows platforms (Windows 95, Windows 98, Windows NT®) support additional premium functionality, including:

Multimedia controls
DHTML–Extended Dynamic Content: the TextRange, Table object model, and associated methods
Data Binding–Remote Data Service
XML parser ActiveX® control
Active Channels: page hit logging
Active Channels: display as screen saver
Active Channels: display as desktop component

In the future, support for the above features might be added to additional platforms based on customer demand.
