How to put out new info to a page.

Question

how can you update a html page without deleting what you have done before?... Lets say I have a blog post, and the next day I want to put out new information. but I dont want the main page to be forever long. can I store it in an archive? make a "menu" bar? Is this where the back end comes in maybee? -level noob

Maybe you can set 'display:none' to the desired container/containers. Or store the info into JSON dictionary. Or something similar with JS.
