Development Progress
This page provides an indication of the current status of various features and gives an idea of where future development will be aimed. Features are split up as follows:
Last updated 20 December 2012

| Web standards | In progress | Most of HTML 4 and CSS 2.1 are implemented which enables NetSurf to access most of the web, however, JavaScript support is currently at a very early stage of development. This means NetSurf currently lacks support for dynamic content. |

| User interface (GTK) | In progress | The nsgtk user interface is sufficient to allow web browsing and supports many features expected of a web browser. |
