CSC 490 Assignment Two - Due March 14th

The first part of this assignment is exposing you to some tutorials. However, there are several questions at the end of Part One that I want you to answer. Then, in Part Two, I want you to answer some questions from the "Head First" book.

PART ONE:

Section 1)

Here I want to introduce you to some resources where you can explore aspects of web technology on your own.

The website for the World-Wide Web Consortium: 

http://www.w3.org/


Here you will find a wealth of material pertaining to the World Wide Web. See if you can find tutorials for HTML and CSS.

This website can be an important source of information for you!

Section 2)

I want you to work through the following tutorials; (A through D)

A) Here's a brief exposure to HTML:

http://www.w3schools.com/html/

Go to first example, look at the code, and click on the button "Try it yourself".
Edit the code to so that "first" in each line is changed to "second"; then press the button "Edit and click me"


B) Then, go to:

http://www.w3schools.com/html/tryit.asp?filename=tryhtml_basic_img

Look at the code in the left window. How do you think that you can change the size of the image in the right window?

C) Then,  go to:

http://www.w3schools.com/html/html_examples.asp

Find the heading: HTML Images

Try to run each example under the heading and look at the code in the left window. Try modifying to code to see what happens!

NOTE: As you are working through the image examples, you might want a further explanation of the code. If you want some "enlightenment" about what is happening, go to:

http://www.w3schools.com/html/html_images.asp

Section 3)

 Please go to the following website:

Read about the SELECT statement

4) Go to the following site:

http://sqlzoo.net/

Under the Tutorial Section (on the left hand side of the page), look at the the following topics:

A) Select Basics (try running the code for each)

B) Select Names (try running the code through number 12)

C) Join (try running the code through number 3)

DON"T HAND IN ANY RESULTS TO ME - THESE TUTORIALS ARE MEANT TO GIVE YOU BACKGROUND
