Hi,
This suggestion is about this article
I think it's important to encourage people to use more HTML options over js ! It's more lightweight and use less"resources", isn't it ?
So I took the example and just change "<button>" into a "<a>" with href to "top" and added id="top" to the first, maybe we can recommend to use an already existing id, the one of the header for example
And after some research I saw that using an "<a>" to go to the top is write as a tip in this article
What do you think ?
Have a nice day
