I have a small problem with the background color of an info box I want to add at the end of some articles on my website. It looks as I want it in the regular version of the website (i.e., dark), while it looks light grey in the AMP version of it. You can check it here: https://www.omniacrystallis.com/2020/09/27/ffxvi-sito-teaser/amp/
Any idea on how to get around this? In the private info field you’ll find the HTML I am using for this effect.
