I am using one of the default templates for SharePoint branding. How do I easily tweak the color as shown below in SharePoint Online? I Googled with no help.
So far I changed the background using a WYSIWYG upload feature. The default WYSIWIG editor does not let me change the white background to SOLID white rather than transparent. As you can see I used inspect element to showcase the change I want to make using CSS. I dont know how to implement it because its SharePoint Online.
