Frequently asked questions about Claros

The code adjusts the height of an iframe dynamically based on its content by posting the height to the parent window.

The height is recalculated by measuring the document body's scrollHeight and then posting this height to the parent window.

The height adjustment is triggered on window load, window resize, and whenever changes in the DOM are detected.

MutationObserver monitors changes in the DOM, such as added or removed nodes, attribute changes, or text modifications, and triggers the height adjustment accordingly.

It ensures that the iframe content is fully visible without additional scroll bars, improving user experience.

The MutationObserver watches for changes in child nodes, subtree modifications, attribute changes, and character data changes.

The postIframeHeight function is triggered by window.onload and window.onresize events.

Yes, the code can be used for any iframe to dynamically adjust its height based on the content.

No additional CSS is required for the height adjustment itself, but CSS may be needed for other styling purposes.

The parent window receives the height data through the postMessage API, which sends the height value to the parent window.
