Part 1; using CSS: Geologic time is divided into eras, periods, and epochs. The eras and their periods are:

Proterozoic: (none)

Paleozoic: Cambrian, Ordovician, Silurian, Devonian, Mississippian, Pennsylvanian, and Permian

Mesozoic: Triassic, Jurassic, and Cretaceous.

Cenozoic: Paleogene and Neogene.

Only the Paleogene and Neogene periods are divided into epochs. They are:

Paleogene: Paleocene, Eocene, and Oligocene

Neogene: Miocene, Pliocene. Pleistocene, and Holocene

Using a document-level style sheet and nested ordered lists, show this information in outline form. The eras must be numbered using upper Roman numerals, the periods must be numbered with upper alphabetics, and epochs must be numbered using decimal numbers.

The background color of the Proterozoic era must be pink. The background color of the Paleozoic era, including its periods, must be blue. The Mesozoic era must have a green background, and the Cenozoic era must have a red background.

Just to make this clear, here is a little bit of the outline:

 II. Paleozoic A. Cambrian B. Ordovician 

I did this with

 elements. You must do it with a document-level style sheet, and you must include the background colors. It is not necessary to match the color I used exactly. 
The easiest way to do this is to make liberal use of class specifications in your document-level style sheet. So, you might code something like this:
 
 ol.eras {list-style-type: upper-roman;} 
 
If you cannot get all this to work using only a document-level style sheet, you may do the numbering with document-level styles and the colors with in-line styles, but try it with all document-level styles first, OK? It can be done.
 
If you can't get color behind the numbers, don't worry too much about it as long as there's color behind the text.
 
Name your document l3p1.html and create a link to it from your index page.
 
Part 2; CSS boxes: Write three or more paragraphs about what you've learned so far about creating usable web pages. You will need at least three "main ideas," one per paragraph. On the same page, put a CSS box using the 
 element. the box should have a two-pixel blue border around it and a light-blue background. Float the box to the right of the text and within the box, put an unordered list of the three or more main ideas, one per list item. Name your document l3p2.html and create a link to it from your index page.
 
Part 3; applying styles to tables: The HTML for a table is provided below. Put this table on a web page named l3p3.html and create a link to it from your index page. Write a document level style sheet for the page that centers the table (left to right) on the page, uses Verdana, Geneva, Arial, or sans-serif for the font family (in that order), and colors and backgrounds as shown in the image. Note: you will not have to include CSS for borders; you will get white automatically in the cell margins.
 
You do not have to match my colors exactly, but the background of the odd-numbered rows must be light blue and the even numbered rows must be light green. The background of the heading must be dark green. (Try a search on "HTML color chart.")
 
Here is the HTML for the table. You will probably want to add class attributes to some of the elements.

Part 4; using alert() and console.log(): Create an HTML document that uses the JavaScript alert() method to display "Hello from " in a pop-up box on the screen. Name your document l3p4.html and make a link to it from your home page.

To your l3p4 page, right after the alert() call, use the console.log() method to log the message "Alert displayed" to the logging facility. Use the console log facility of Firefox with Firebug or Chrome to verify that the message was logged.
