Right click on this page.

Select "View Source".

At some point, you will run into WebPages where if you right click to 'view the source', you get a warning message, or no result at all. Then you will have to:

Use the "VIEW" option at the top of your browser window.

Then select "SOURCE".

While you are looking at the source, notice that everything is in-between the beginning and ending meta tags. They look like this: <html> at the top of the source page,; and like this: </html> at the very bottom of the page.  HTML is Hyper Text Markup Language. It is the base on which all WebPages are constructed.

Below the opening <html> comes <head>&</head>tags. The information between them usually contains keywords,  title and description for the page, most of which helps search engines find your site or page or auction. If you're making a page to turn into the body of an email message, you can get away with nothing between the <head> and </head> tags.

In between the <body> & </body> tags is where you see most of what is on this page.

You can see different codes used for making colors.

Or if you use simple colors (red blue yellow black white orange purple green gray magenta pink) then you can simply type their name instead of using hexadecimal values

here is a link to the color picker

Now click on file at the top of this window, and select "Save As..."

Then save this page to your desktop.

Once you have saved it, then open it from the desktop.

View the source.

Make some changes to the source code. Or the text. Click on "File" then click on "Save"...

Close the Notepad.

Refresh the internet browser window.

Do you see your changes?
