I am not sure what exactly you want to achieve.
If you want the whole page, you can use a screen capturing software like ScreenToGIF (https://github.com/NickeManarin/ScreenToGif/releases) or ShareX (https://getsharex.com/downloads/), select a region to record and move your cursor outside the region. You will have the effect and part of the text elements.
If you only want the mountains, you need to change the page code to hide the text elements. You can do that by opening the dev console and hiding a text element.
As you can see, there is a
data module="text" in the title and so I right-clicked on it and selected “Hide element”. I can add more detailed instructions if necessary.And to actually be able to use it, you can again just screen capture it.
