I work as an administrator and have been asked to change the look of a few sites. We have sharepoint 2013 on-premise. Are there any risks of override the existing CSS? Is there something I should definitely avoid?

On-prem, that will be risk free as the DOM won't change for that product. It becomes a larger issue in SharePoint Online where the DOM can change at any time as Microsoft updates the product.

  • Glad to hear! Can I point to a CSS file through a snippet, or could it cause a problem?

SharePoint Color Palette Tool is I guess one of the best and simpler tools for branding / changing CSS for the site. You can refer this for How-to do stuff Alternatively, you can also try Alternative CSS URL

All the best!

  • Thanks man, looks good! Sadly, I do not have permission to enter the "Themes" section
