Custom theme or CSS in SharePoint Online

Question

Hi, 

I want to do some custom theming in sharepoint online. I want that the color is exact the same as the color of our company. I found a tool for sharepoint2013 (https://en.share-gate.com/blog/create-sharepoint2013-theme-using-color-palette-tool) to make my custom theme. But I don't know how to upload this file to my Sharepoint Online site. Or is this not possible? Or is there any other way, maybe I can use CSS?

Like you see in the picture, it is possible to change the theme and some extra style but I need a specific color (just like one the top bar).

Hi Axel,

I apologize, I didn't completely finish the test mentioned in my last reply. It appears in this newly designed site collection, even the global admin has the full control permission, he still has the Deny permission level:

(Deny - Add and Customize Pages

Add, change, or delete HTML pages or Web Part Pages, and edit the Web site using a Microsoft SharePoint Foundation-compatible editor.)

Thus the customization for the site will be disabled, enabling the custom script won't help either.

Given this situation, you can either customize other site templates, like a team site or community site, or submit this feedback by clicking the button in the bottom right corner of your Communication site home page. We'd appreciate your understanding.

Thanks,

Jim

Hi, 

that was a good answer because it wasn't checked. I did it immediatly, but it still isn't changed. (23h now..?) Maybe I just need to wait a bit more.

kind regards

Answer 4

Hi Axel,

I tested as what you've described, this is a newly designed site collection template, so the buttons are not displayed. But I can still access these settings via URLs. See if it works for you:
