HTML Error Code Descriptions

[estiger]

I'm new to HTML. I coded my first template in Marketo, and I'm getting an error code I'm not familiar with.

Is there a good resource to learn more about HTML error codes? My specific code is "Error: Multiple Container Elements..." Ideally, someone could direct me to an article or database to search this error and learn more about what is causing it.

Thanks!

At the bottom is the Container description. You can only have one class="mktoContainer" in your HTML and all modules must be within it. Hope that helps.
