Theming

The Theming tab in the Developer Portal's Settings page lets you replace a view's look and feel — colors, layout, partials, and images — by uploading a ZIP archive, and roll back to the built-in default at any time.

Theming is configured per view: if your organization has more than one view, use the view switcher at the top of the panel to pick which one you're theming.

Applying a Custom Theme

  1. Navigate to Settings and select the Theming tab under APPEARANCE.
  2. Pick the view you want to theme, if you have more than one.

  3. Under Upload Theme, drag and drop (or browse to) a single ZIP archive containing any of:

    • styles/ — CSS
    • layout/ — the Handlebars layout template controlling page structure
    • partials/ — Handlebars partials
    • images/ — logo and other image assets

    Up to 10 MB.

  4. Click Apply theme.

Uploading replaces the current theme entirely

Applying a new ZIP replaces this view's existing custom theme files completely — it isn't merged with what was there before. Use Download theme first if you want a backup or a starting point to edit.

The panel's Current theme indicator shows whether the view is using a custom uploaded theme or the built-in default.

Downloading the Current Theme

Click Download theme to get a ZIP of what's currently applied to the view. If the view has no custom theme, this downloads the built-in default theme instead — so it always gives you a valid starting point to customize.

Resetting to the Default Theme

Click Reset to default to discard the view's custom theme files and revert to the built-in default. This can't be undone — download a copy first if you might want it again.

API-Level Content

Theming here controls the view-wide look and feel. To customize an individual API's landing page content (its own documentation, description, and assets), see Manage APIs.
