Is it bad to nave no ?
I have this basic structure but I am thinking about wrapping a header arround everything between the body start and
Decide for every sectioning root element (e.g., body) and every sectioning content element (e.g., article) if it contains content which is appropriate for header. The spec defines that it’s for "introductory content", and gives the following examples:
h1–h6 element) (not required)If there is such content, use a header element. If the content in that sectioning root/content element is scattered, use several header elements.
Keep in mind that the header always applies for "its nearest ancestor sectioning content or sectioning root element":
<body>
<header> <!-- this header is for the whole page --> </header>
<article>
<header> <!-- this header is for the whole article element --> </header>
<div>
<header> <!-- this header is also for the whole article element (and not only for the div element!) --></header>
</div>
<section>
<header> <!-- this header is for this article’s section element only --> </header>
</section>
</article>
<figure>
<header> <!-- this header is for the figure element only --> </header>
</figure>
<strong>
<header> <!-- but this header is also for the whole page (and not for the strong element only!) --> </header>
</strong>
</body>
