About

What is Claros?

Claros is a JavaScript script designed to enhance the user experience of embedded iframes. It dynamically adjusts the height of an iframe to perfectly match its content, preventing the appearance of scrollbars and awkward empty spaces. The script leverages 'postIframeHeight' and 'MutationObserver' to continuously monitor for changes within the iframe's content and resize it accordingly. This automation provides a cleaner, more integrated look for embedded content, making it appear as a natural part of the parent page.

FAQs

How does Claros handle content that changes dynamically within the iframe after initial load?

Claros utilizes 'MutationObserver' to continuously monitor for changes in the iframe's content. If content is added, removed, or resized after the initial load, Claros will automatically adjust the iframe's height to accommodate these changes, ensuring scrollbars remain absent.

Are there any known compatibility issues with specific browsers or complex iframe content?

Claros relies on modern browser APIs like 'MutationObserver' and 'postMessage'. While widely supported, very old browsers might have limited functionality. Complex content with deeply nested structures or rapid, continuous layout changes could potentially impact performance or require fine-tuning.

Does Claros require any modifications to the content inside the iframe itself?

Yes, for Claros to work effectively, the content inside the iframe needs to send its height information to the parent page using 'postMessage'. This typically involves a small script within the iframe's content to report its current height.
