Custom CSS/JS injector – FREE DOWNLOAD
Classic SharePoint pages could be modified by changing the master page and applying new CSS styles.
Modern SharePoint pages come with far fewer styling controls, and there’s no out-of-the-box way of adding your own CSS to their pages.
The custom CSS/JS injector allows you to do precisely that by loading files called custom.css and custom.js from the root SharePoint site’s style library, which it then adds to all your modern SharePoint pages.
The zip file you can download here contains a SharePoint Framework solution compatible with SharePoint Online.
If you need a version of this extension that uses a different CSS or JS file names or locations or a version compatible with SharePoint 2019/SE or SharePoint 2016, just let us know, and we’ll make it for you.
Fill out the registration form below and click the button to download a zip file containing the .sppkg SPFx solution file.
If you wish to deploy this solution to your entire SharePoint Online environment
you need to add this solution to your tenant app catalog.
To do this you must be a SharePoint Administrator or a Global Administrator.
If you do not yet have a tenant app catalog (usually created at the URL https://your-tenant.sharepoint.com/sites/appcatalog) you can create one easily.
- Open your SharePoint administration site (https://your-tenant-admin.sharepoint.com/)
- In the left sidebar, select ‘More features’
- Then locate the section ‘Apps’ and select ‘Open’.
This will start the automatic creation of the tenant app catalog if it does not exist.
In the tenant app catalog you can upload the .sppkg file from the downloaded zip file and choose whether to just enable the solution without adding it to any SharePoint sites (Only enable this app) or enable and add the solution to all SharePoint sites (see image).
The first option will make the solution available on all SharePoint Online site collections, but will have to be enabled on each site collection individually.
The second option will make the solution available and enable it on all SharePoint Online site collections, even site collections created in the future.
More information about managing apps in the tenant app catalog can be found here.
If you wish to deploy this solution to just one or more specific site collections without it being available in other site collections, you need to deploy the solution to site collection app catalogs created in each specific site collection.
For more information on how to create site collection app catalogs and how to use them, please read this Microsoft article.
