This is Google's web site builder! It has been around for years, but was completely revamped in 2016. This site is built on a Google Site.
Help?! Kids can't see my site!!!
Try this:
https://drive.google.com/file/d/1lnOO_be42n67jemrLDSqRdXpNoeIyG4r/view?usp=sharing
Tips:
Even though Sites saves automatically, nothing is visible to the outside world until you click on PUBLISH. The first time you do so you will have to name the site and decide who gets to see it. Press PUBLISH after any changes you make.
You can build ahead and hide pages from navigation, making them visible when you are ready. Under the PAGES tab, mouse over a page and you will see the three vertical dots revealing options. One option is to HIDE the page from navigation.
Files you attach to Sites must live in Google Drive. When you have something in Google Drive that you want to put in Sites you must make sure that item is viewable. By default things you put in drive are private only to you. (See below.)
Select the file and click on the person + (share button)
Click advanced.
Click Change.
Select ON. I suggest the top one.
