No css on posts page across multiple themes

Please make your site visible. I see a coming soon page.

Whoops, sorry, that was a Bluehost option I was unaware of. Should be visible now.

I see 3 missing images on the blog page, but what I see that seems to be the problem is that you have a lot of inline CSS. Did you copy/paste this content from someplace else? It seems to have picked up the styling form the original source.

Select the text in question in each post and click the little eraser icon to remove all the inline formatting.

The problem is too much CSS, not no CSS.

Should have also mentioned that turning any other page into the posts page yields the same result.

I’m aware of the pasted-in css in the content, but that is not the problem. The site title, subtitle, menus, post titles, etc,. all lose their formatting. If you click on a post-title, date, etc,. and view the single post, the formatting is as it should be. I’ve made that long pre-formatted post private to remove it from the confusion. Thank you for looking.

For comparison, the Materials menu item is a category page, and formatting works okay for everything there.

I’m not seeing the cause.

This may be a plugin or theme conflict. Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles.

If you can install plugins, install “Health Check”: https://www.ads-software.com/plugins/health-check/ On the troubleshooting tab, you can click the button to disable all plugins and change the theme for you, while you’re still logged in, without affecting normal visitors to your site.

I disabled all plugins and tried it default themes 2015-17 with no success.
Whatever page became the posts page lost its formatting.

Next, I made a new index.php for the child theme and tried copying and editing some of the php from the beginning of my category.php page into it, since the category page worked. At some point the Recent Posts page appeared properly, but at that point it was identical to Twentyseventeen index.php, and after I disabled the child index.php, the page still appeared correctly. So the frustrating mystery was never solved, but now the formatting is mysteriously correct. I’ll take what I can get.

Thank you for giving it your attention.

Finally found what was breaking the styling: when all inline styling from content was removed, everything works as it should.
