Data-Stream allows you to build web sites that follow the web standards:
XHTML
The code rendered by Data-Stream is compliant with XHTML 1.0 specification. Moreover, we use a unique output filter that fixes XHTML incompatibilities introduced by the ASP.NET 2.0 engine.
Of course, it also depends on the code that you render in your page templates, transformations and on your content.
The built-in WYSIWYG editor automatically fixes the entered content so that it contains valid XHTML code.
CSS Layout/CSS Positioning
Data-Stream supports both table - and CSS - based layouts/positioning. You can easily create web sites without tables. You can also use the CSS-based menu control that renders UL/LI elements, without any JavaScript.
