Everything you see on this panel (see samples on the left) is custom-painted
by the HTML Renderer, including tables, images, links and videos. This project allows you to have the rich format power of HTML on your desktop applications without WebBrowser control or MSHTML. The library is 100% managed code without any external dependencies, the only requirement is .NET Framework 4.6.2 or higher, including support for Client Profile. |

- Handle :hover selector
- Selection by shift+arrows
- Better HTML tag parsing (optional closing tags)
- More styles support
Vision
