Lite HTML engine

The Lite HTML engine is created for embedding into applications, to show the HTML code. Lite HTML supports most of the CSS2/CSS3 standards. The engine is written on C++ with STL (MS Visual Studio 2008) and was tested on Windows platform only.

Embedding Lite HTML

Firstly, the Lite HTML don't have the code for draw anything. You are free to use any draw engine. We've included the win32_container class as example to show how to implement the draw code.
