This code will be centered

The style used in this example are pre CSS and are not considered good code and will not validate. I am showing it to you because part of web development is upgrading pages so you should be familiar with the different approaches.

This is not centered

This is another way to center - the command has been depricated

You can use left to align as well although left is the default.

You can also right align using the align clause.

This Web Page has a non white background because the background color was set to FFFFC2. Note that #FFFFFF is pure white and #000000 is pure black. I randomly put in 000BBB for the text and got a blue coloring.
For the list of different codes and colors, go to my Web site and look for a listing under colors. NOTE: The # in front of the color code is not required in HTML.

This gives me a large font
This gives me red text
Note that for standard colors, I can assign the color red to the font. For more subtle shades, I need to use the code for that color. Read about how colors are treated by browsers and true colors. In this example I used 00dd00 which gave me a shade of green.
