Development Questions

[Juan M Baena]

Good Day:

Although our focus with SharePoint Online has not been custom development, we have been asked several times what supported options are there for adding custom markup code and classes for helping customize the look and feel/behavior of elements within modern pages.  Would we need to go the route of a SharePoint Framework solution? Thanks

[#2 · Accepted solution]

Yes, SharePoint Framework is where you should go :-): both SPFx WebParts and SPFx Extensions are your options here

@Juan Carlos González Martín  @Juan M Baena Yup this the correct option.


Side note - If you are trying to modify the *existing* styles and behaviors of the modern pages. This is not supported and you should not try and do that.

Thank you all!
