Pull Request

📖 Description

With the project re-alignment goals (#6955) this change seeks to highlight the use of @microsoft/fast-element as the package the documentation site is now focused on. This is similar to the previous frontpage for v1, however the content has been amended to get the user started on @microsoft/fast-element and states the updated project goals.

On small screens, the content overflows and requires horizontal scrolling to see all content. The content should wrap within the max width of the viewport. One exception are the code blocks, which should min-max their container widths and horizontally scroll their inner contents if there's not enough space.

@radium-v thanks! Please take another look, should be working better now without the overflow issues.
