Live preview
Interactive Obsidian workspace preview
Switch between supported modes and workspace layouts. The preview loads the theme's real CSS in an isolated Obsidian-like frame, so split panes, reading view, source editor, callouts, tables, tags, and checkboxes can inherit theme styling.
Actual CSS preview
This isolated Obsidian mock loads the theme's real CSS from its GitHub repository, so special fonts, backgrounds, callouts, tabs, and editor rules can render much closer to the installed app.
