rss page

Hi

I got a button now on my website for rss feeds but when the button is pressed the page it goes to doesnt look very nice, its all a big bunch of ugly text, it works, because I’ve tested it but is there a way to make that page look nice like CNNs: https://rss.cnn.com/rss/cnn_topstories.rss
Is there something I have to make the server do?

Thanks
