I’m not seeing any recent formatting changes in relation to the “news” part of the web site.
The Help Centre article you provide is from “1 month ago”. It also tells you how to go back to the old “home page” if that’s what you prefer.
It is not unheard of for network problems to cause CSS files to be absent from the web page in the browser, which can cause dramatic changes to appearance.
So I am not certain whether there is a problem and if so what it is?
Can you mention what operating system and version, browser and version? Can you clear your cache so that you are starting in a known state?
Possibly if you are accessing from a mobile device (smartphone, tablet) - you haven’t said - you are seeing differences that other people not using a mobile device are not seeing.
