LaunchDarkly + Ghost: using feature flags to change styles in your CMS

To add LaunchDarkly feature flags to a Ghost CMS, one must first create a hosted Ghost account and obtain a free LaunchDarkly account. The user then needs to paste a specific code snippet into their site's footer tab in the Ghost admin panel, which uses LaunchDarkly's JavaScript SDK to check if a dark mode flag is enabled. When the flag is on, it changes the site's styling by modifying various CSS properties. A new feature flag is created in LaunchDarkly with a custom configuration, and its client-side ID is copied and pasted into the code snippet. The user can then toggle the flag on or off to test different variations of their website's design. This technique allows for easy experimentation and personalization of content without requiring extensive coding knowledge.
