The Button web part lets you easily add a button to your page with your own label and link.
Note: Some functionality is introduced gradually to organizations that have opted in to the Targeted Release program. This means that you may not yet see this feature or it may look different than what is described in the help articles.
Add the Button web part
Go to the page where you want to add the Button web part.
If your page is not already in edit mode, click Edit at the top right of the page.
Hover your mouse above or below an existing web part and you'll see a line with a circled +, like this:
Click +, and then search for and select Button from the list of web parts.
Select Edit web part in the toolbar on the left.
In the property pane on the right, enter your label text in the Label box.
Enter your link in the Link box. Make sure your link starts with http://, https://, or mailto: If your link is added without one of these protocols, https:// will be added for you.
Under Alignment, choose how you want the button aligned (left, center, or right) within its column on the page.
