why is enable critical css give me now Prioritize visible content ?
because your critical CSS does not allow the above-the fold part of the page to be rendered in a manner that is close enough to the final rendering. in the google pagespeed insights results, you’ll see;
Only about 17% of the final above-the-fold content could be rendered with the full HTML response see screenshot show original.
and you can click on “see screenshot” and “show original”. this gives you an idea of what GPSI thinks is missing.
the problem you’re facing; some (a lot) of what google is missing, is rendered based on JS (the news-ticker & the image slider for example). the tools that generate critical CSS in general don’t see that, so you might have to amend the critical CSS by hand to ensure (at least) the divs that will hold the JS-based stuff have the right size. that _might_ appease GPSI.
I’ll try later
I see you did in the mean time and that it indeed works ??
