Take a look at some very simple Web pages:

I guess that you just copy and then paste the above into your Web browser's address space and then click Enter, that is click on the Enter Key.

Thru the years I built a few more or less simple Web pages and or Web sites, I said "simple", I don't know much about Web page making nor about HTML, but what I did, I did by looking at the "sources" of a few Web pages and also at a few simple HTML tutorials, that was long ago and I don't remember much about that, but if I wanted to, I probably could again build some sort of more or less simple Web page(s), but very simple pages.

I don't at this time, have Web space, but there are some free Web space hosts that I could try if I wanted to.

I think that my first WebPage was hosted on Yahoo!, back on the days when Yahoo! gave free WebSite hosting.

I don't remember if I ever used Geocities or not, but long ago on Earthlink I was given some free space and posted a simple WebPage there, those pages that I had are gone.

I made those WebPages just to see if I could do it and for no other reason, maybe in the future I will again put-up a page or pages somewhere.
