Keep the result visible next to the code and make preview dimensions easy to change.
Design notes
Surface
Live editor
Navigation
Language tabs sit above the source; preview-size controls and sharing sit in the top bar.
Layout
The source editor fills the left half and a preview of the built-in example fills the right.
Density
Primary content has the most space; repeated rows and secondary navigation use a compact, consistent rhythm.
Color
White panes with syntax colors and a clear cyan product accent.
Type
Reserve almost all of the screen for editing and previewing rather than surrounding chrome.
Pattern
Keep the result visible next to the code and make preview dimensions easy to change.
States
The supplied example is loaded in the public playground; no code was published.
Don't
Adapt the interaction pattern to your own product. Do not copy brand assets, sample identities, proprietary text, or assume unseen states. Specify keyboard behavior, loading, empty, error, and narrow-screen layouts for your implementation.
