Container Advanced HTML Tag info?

[PLM (Per Martins)]

When I started playing around with these tags, my Google PageSpeed score for Accessibility jumped to 100. Before I got flagged for missing the Main Landmark.

Is there any info in the manual about the different Advanced HTML Tags and how to use them? @dan

I tested some more tag settings and Performance improved from 90 to 94. I will not get 100 since my photos are too large and not enough compressed …
