Is nestling section elements bad? The spec recommends that the section element isn't used as a container, but I used it as one.
The spec states:
<body> <section><!-- wrapping section --> <header><-- header of HTML page (logo, nav, etc) --> </header> <section><!-- the body of the page --> </section> <footer><!-- the footer of the web page (copyright, etc) --> </footer> </section><!-- closing section wrapper -->
The section element represents a generic document or application section…The section element is not a generic container element. When an element is needed for styling purposes or as a convenience forscripting, authors are encouraged to use the div element instead.
