Remove SLDS

If necessary, you can remove Salesforce Lightning Design System (SLDS) from your site.

Don’t remove SLDS if you plan to use flexible layouts or any of the Lightning base components, as they rely heavily on the design system.

Important

In Experience Builder, click Settings | Advanced | Edit Head Markup, and delete the following line.

1<link 
2    rel="stylesheet" 
3    href="{ basePath }/assets/styles/salesforce-lightning-design-system.min.css?{ versionKey }" 
4/>

To use SLDS again later, add the code back to your head markup.
