When I put a website I am building through a W3C checker it asks me to consider only using h1's as a top level heading and points out a section where I have a h1 inside of a section. It also mentions that screen readers will treat them all as top level elements, however, according to HTML5 specs, sections effectively "reset" the headings so you can start another hierarchy from 1-6 within them.
Should I only be using h2-h6 within sections if we are trying to focus on W3C validation and accessibility? Or is this warning incorrect?
