| Description | The Theme Handling Script dynamically manages the theme settings of the document based on the user's preference stored in localStorage or the system's color scheme preference. It ensures a seamless user experience whether they prefer light or dark themes by efficiently adding the corresponding class to the document. If there is no specified preference, the script defaults to the system preference. | The JavaScript function 'postIframeHeight' is designed to dynamically adjust the height of an iframe based on the content's scroll height. This function sends the calculated height to the parent window using the postMessage method. It is triggered on the iframe's initial load, resize events, and any changes in the iframe's content, which are detected using MutationObserver. This ensures the iframe height adapts in real time to the content changes, providing a seamless viewing experience. |
