    --------------------------------
    The example of the html content is: {html_content}

    Try to select the deeper class that is common among the elements to make de find_all function.

    Your answer SHOULD only contain the python function code without any aditional word or character.

    Import the used libraries above the function definition.

    The function name must be extract_info.
