I want to know if I can use a header tag in footer inside section.  I also want to know if this follows SEO.For example, I made four section boxes in footer:<footer><div class=ftr_top><img src=media/footer.png></div><div class=ftr_bottom><section class=ftr_section><header class=ftr_head><h3>Box 1</h3></header><ul><li></li><li></li><li></li></ul></section><section class=ftr_section><header class=ftr_head><h3>Box 2</h3></header><ul><li></li><li></li><li></li></ul></section><section class=ftr_section><header class=ftr_head><h3>Box 3</h3></header><ul><li></li><li></li><li></li></ul></section></div></footer>
Can I use a header tag in footer inside section?

It's not valid HTML5 to have a <header> element inside a <footer> element. You could have checked this yourself on this site:http://validator.w3.org/checkFor using <header>, <footer> and <section> correctly, see this page:https://developer.mozilla.org/en-US/docs/Web/HTML/Element/footerFor even more technical details, see the HTML5 specification:http://www.w3.org/TR/html5/sections.html#the-footer-elementSpecial thanks to @amon for the links!
