Does the front end support multiple html files?

Does the front end support multiple html files?If does how to configure.I deployed my blog using fleek, but when I click the article it won’t jump to the article’s page. Each article is a separate html file.
Here is my blog : https://kluy7-aiaaa-aaaad-qamvq-cai.raw.ic0.app/
But when I use the fleek url : https://kluy7-aiaaa-aaaad-qamvq-cai.ic.fleek.co/ , It works normally. Can anyone explain this? Thanks!
