Never use a space in any file name. All web pages must end in .htm or .html . They must have been saved in the same format as what they are named. Keep the file name short. As , you are saving the code as an HTML file, which is a web page.
Every web page has a name that ends in .htm or .html.
This is how the browser knows it is a web page. The very first page of your web site must be names index.html or index.htm. Now you have to title your web page. The title is what will appear in the title bar of the window when someone else views your page on the World wide Web. Search engines look first at your title and decide from that where to add this page to their database so others canfind you.
