Hi dhruvxverma,

Thank you for reaching out to Microsoft Community. I understand you're looking to create an announcement banner in SharePoint without any additional extensions or add-ons. It's important to clarify the difference between a "ticker" (which usually implies scrolling text) and a "banner" (a static, prominent message).With the "no extensions" constraint, a scrolling ticker banner that appears on every single page across your entire SharePoint site is not possible out-of-the-box. However, you can absolutely create a prominent, static announcement banner at the top of specific pages, like your Home Page.Here are the best ways to do this using only built-in SharePoint features:1.Simple Announcement Banner with Text Web Part

• Go to your SharePoint site’s home page (or the specific page where you want the banner).
• Click Edit in the top right corner.
• Scroll to the very top of the page. Hover your mouse above any existing web parts until you see a "+" icon. Click it.
• Search for and select the Text web part.
• Enter your announcement text directly into the web part, e.g., “Scheduled maintenance on May 30th, 10 PM – 2 AM.”
• Format the Text to Make It Stand Out:
  • Highlight the text you entered.
  • Use the formatting toolbar that appears to:
    • Make the text bold.
    • Change the font color (e.g., white or a bright color).
    • Click the Background color button (paint bucket icon) for the section that contains the Text web part. Choose a bright, contrasting color like red or yellow to make the entire section act as your banner background.
• Click Republish or Publish at the top right to save your changes.

2. Dynamic Announcement Banner with News Web Part (Recommended for Regular Updates)This method is great if your announcements change regularly, as it allows less technical users to update the banner by simply publishing a new news post.
3. Create a dedicated News Post for your announcement:
   • From your SharePoint site's home page, click + New > News post.
   • Create a concise news post containing your announcement. Use a clear title and body.
   • Publish this news post.
4. Add/Configure the News Web Part on Your Home Page:
   • Go to your SharePoint site's home page and click Edit.
   • Add a News web part at the very top of the page (using the "+" icon).
   • Click the pencil icon (Edit web part) on the News web part.
   • Under "News source," choose "This site" (or "Selected sites" if your news is from a specific source).
   • Under "Layout," select "Single post."
   • Under "Show as," choose a prominent display like "Top story."
   • You can also filter by "News posts that are..." and select a specific News Post if you want to explicitly control which announcement is shown.
   • Consider setting a contrasting background color for the section containing the News web part to make it stand out.
5. Publish the Page: Click Republish or Publish at the top right.

How to update this banner: To change the announcement, you simply create a new news post (or update the one you're filtering for), and the News web part will automatically display the latest "single post" on your page.We appreciate your patience and hope these options help you create a prominent announcement banner on your SharePoint page. If you need assistance with Microsoft 365, Office, or Outlook, feel free to post back here anytime. Kind regards,
