Reference overview
Lookup material rather than reading material: specs, tables and name lists you consult mid-task and then close.
System requirements
The official supported minimum for Site Designer on Windows and macOS.
Keyboard shortcuts
The shortcuts confirmed in CoffeeCup's documentation, the platform standards you can rely on, and where to read the rest inside the app.
File format and project structure
What is actually inside a .rsd and a .rsdtheme file, and how to open one without the app.
Supported file types
What image, font, and video formats work in Site Designer, and where the general web-format guidance ends and unverified specifics begin.
Browser support
What's actually verified about cross-browser support in Site Designer's output: the picture element polyfill and the Feature Queries tool.
Where to find each CSS control
A lookup table pointing from a CSS property to the article that covers its Style pane control.
Framework class quick reference
Look up grid, spacing and component class names across Foundation, Bootstrap and Materialize.
