To replace the image in your button with an icon that is part of the button and still be able to add a link block in Webflow, you can follow these steps:
1. First, add a `Link Block` element to your Webflow page. This will act as the button that you can click to navigate to a different page or URL.
2. Inside the `Link Block`, add a `Div` element to act as the button container. This `Div` will hold both the icon and the text of the button.
3. Add the desired icon to the `Div` element. You can use Webflow's built-in icon library or upload your own custom icon. To do this, select the `Div` element, go to the Styles panel on the right, and click on the "+" button next to the `Background` property. From there, you can choose an icon or upload your own.
4. Adjust the size and position of the icon using the `Width`, `Height`, and `Position` properties in the Styles panel.
5. Now, add a `Text` element inside the `Div` container and enter the desired button text.
6. Style the text using the typography and color options in the Styles panel.
7. Lastly, select the `Link Block` element again and go to the Settings panel on the right. From there, you can set the destination URL or choose a page within your Webflow project to link to.
By following these steps, you can create a button in Webflow that includes an icon and still functions as a link to navigate to another page or URL when clicked. Don't forget to customize the button's appearance using the various styling options available in Webflow.
