Hello, I am trying to add custom CSS to the theme “Maker” to make the logo centred on all pages. I am changing the code on the theme setting tab. Code: .header–container { justify-content: center; display: flex; } I am getting an error that says “Online Store editor session can’t be published”…

Hi @Toast2000toast To add your custom Css Paste your code in theme.css file in asset .header--container { display: flex; justify-content: center; } . I hope this will help you if not please share your store URL and password if you enable Thanks

Hi @Toast2000toast , Glad to support you today. Your code doesn’t wrong but you should add the correct place. If your theme has a file theme.css or base.css, pls add that code under the file: [GemPages_0-1676273329692.png] I hope you find the answer helpful. Kind & Best regards, GemPages Supp…

I’m also getting this issue trying to use the new custom CSS section editor: [Screenshot 2023-02-13 at 1.26.20 PM.png] [Screenshot 2023-02-13 at 2.21.30 PM.png] The suggestions given above are obviously useless because we know that we can use CSS files to style the theme but the idea here is to …

EDIT: Shopify support says that you can’t use position: absolute in the custom CSS editor (like at all??) and you also need the selector you are trying to apply be apart of the hardcode, it can’t be a custom liquid section or something like that… Seems like two kind of dumb limitations to me but may…

I’m also getting the same error and it only happens when I try to make the position absolute in the custom CSS section, which is exactly what I need ONLY for that specific page. If I change it in a asset file it changes the whole website. Any fixes so I can make it absolute?

Yeah shopify support said they currently don’t allow position: absolute or any property value that requires a comma. I was told the second one was a bug and would probably be fixed but the first one may be here to stay… Definitely reach out to support so they know that a lot of us want to be able …

Supposedly they have pushed a fix for position: absolute but no word yet on the slightly more complicated selectors.

Hi all, was there an update to this? I am getting the same error and was directed to this post by the shopify support. I was trying to style a button in the custom css tab. The initial code I used worked: .button.button–primary { background-color: black; transition: background-color 0.3s ease-…

I’m also having issues but found a workaround to use all the css selectors which aren’t yet supported. Probably not a recommended solution but it works for me: Find the page you are trying to modify in Customizer. Add a Custom Liquid Block at the bottom of the page and set margins to 0 or ver…

I was having this issue. I had some custom css code that I commented out in the editor panel.

Once I deleted that css code I was able to publish.
