I am going to host my own website, using Microsoft's ISS to host them. My question is that when I am hosting them, and I want to update them with a newer look, will I just be able to edit my HTML code and then the next time the page loads it will show the new content?
Always have a production site and a test site. Do all changes to the test site and then when you are happy, copy the entire thing over to production. If you are using something like asp.net, don't copy the web.config as that will typically have settings specific to that environment (database connection strings for example). If you are connecting to a database, you shoud have production and test versions of that as well.
we can change and update any webpage using Hosting account, with the help of File Manager.
