CSS problem with post / article

Hi !

After reading an article in french about your plugin (http://bloginfos.com/better-amp/), i decided to test it.

Good job, it works with home, categories but it doesn’t work with articles or posts.

I desactivated your plugin but the website where i heard about your plugin seems to have the same problem (check the AMP version of the article : http://bloginfos.com/amp/better-amp/).

No CSS style for articles or posts, it’s weird …

Best regards

Steve
