I have a slideshow on my home page. The slideshow have no content, only background images.
The question: Should I mark it up as a section or anything else? Maybe skip the HTML5 markup?
<header></header>
<div id=slideshow></div>
<main></main>
<aside></aside>
<footer></footer>
I guess a DIV would be fine. You could use section if you have a header for the slider and maybe a paragraph also. It's a list of images, right? So make an UL with the images inside, and remove the bullets with CSS.
