[femina1970]

We are using SharePoint Online portal in our organization and it use as some customizations with CSS .sometimes  the portal home page is loading with corrupted format .we need to adjust the CSS to be in correct format . Is there any fixed solution for this ?

Customization is applied to the organizational level .Whichever the site we create it inherit the same CSS .

@femina1970 How you have applied custom CSS to SharePoint sites, using SPFx application customizer?

If yes and you have original code used to develop SPFx application customizer, you can update the source code as per your requirements and redeploy the solution with correct CSS.

Check: How can I include the same JS and CSS files on multiple SharePoint Modern Page?

@femina1970 You have to edit source code of your SPFx solution:

1. Change value of skipFeatureDeployment property in ./config/package-solution.json file to false
2. Re-package the solution
3. Deploy/Update the solution in tenant level app catalog.

Follow below documentation for more information:

1. Tenant-scoped solution deployment for SharePoint Framework solutions 
2. Deploy your extension to SharePoint (Hello World part 3)
