Is there any way to format text in SharePoint image captions?

However, the SPFX solution will still work after it is disabled automatically as the SPFx solution runs within the SharePoint Framework and doesn't rely on the custom script settings for its execution.

Is that documented anywhere? There have been many posts about script editor web parts not working after custom scripting is disabled. I haven't come across that but given the confusing information communicated by Msft, this really needs an official, clearer answer. I haven't seen anywhere that custom scripting is ONLY needed for installing solutions, and that they'll continue working after it's disabled.

Ah, I see. I think this fully clarifies my options. This is my understanding:

• Custom script is required to render HTML or ASPX files in Libraries other than Site Pages. Using the Embed web part relies on this. This is therefore not an option unless my organization allows custom script. This seems unlikely, and appears to be deprecated by Microsoft. https://learn.microsoft.com/en-us/sharepoint/security-considerations-of-allowing-custom-script
• Modern script editor and InjectCSS would have to be deployed by my administrator. (They may need to enable custom script temporarily in order to get them into the app catalog, but I don't have to worry about that.) They could then be used to format page parts through CSS, respectively on a page or throughout a site.

Is that correct?

Dear James,

Thanks for your updates.

Yes, Custom Script is temporarily needed for the SPFX solution. However, the SPFX solution will still work after it is disabled automatically as the SPFx solution runs within the SharePoint Framework and doesn't rely on the custom script settings for its execution.

Thank you for your time and effort.

You say, "the alternative way of the custom script is the SPFX solution". I cannot understand.

The Modern Script Editor is an SPFx solution. However, custom script must be enabled in order to use it: https://www.sharepointdiary.com/2020/11/add-custom-css-to-sharepoint-online-modern-page.html. So how are they alternatives?

Do you perhaps mean that custom script is required to install an SPFx solution, but that once it's installed custom script can be disabled, and the SPFx solution will still function?
