What are SharePoint Modern Pages and HTML Codes?

SharePoint Online is a cloud-based service that helps organizations share and collaborate with colleagues, partners, and customers.

With SharePoint, you can access internal sites, documents, and other information from anywhere—at the office, at home, or from a mobile device.

SharePoint Modern Pages are a versatile way to create and share content in a visually appealing and user-friendly manner within SharePoint Online.

They offer a flexible canvas for building web pages, news articles, and more.

Troubleshooting Issues and Solutions

While adding HTML code to your SharePoint Online modern page is a valuable customization option, it can sometimes lead to issues that need troubleshooting.

Here are some common problems you may encounter and solutions to resolve them:

1. Broken Code or Display Issues:

  • Problem: Your code may not display correctly or might appear broken on the page.
