    or use the W3 HTML Basics Review & W3 CSS Tutorials.

    Use the CSS Reference to look up the following:

    • color,
    • background (-image, -color, -attachment, -position, -repeat),
    • border (-top, -left, -right, -bottom),
    • margin (-top, -left, -right, -bottom),
    • padding (-top, -left, -right, -bottom),
    • position (and top, left, bottom, right),
    • width,
    • height,
    • text-align,
    • text-decoration,
    • font (-family, -size, -weight, -variant),
    • list-style (-image, -type)

    Create an HTML page with 5 buttons. When a button is clicked, it loads a background image onto the body. Each button loads a different background image.

    Hint: You can start with the HTML code from this tutorial.
    Learn how to change the innerHTML of HTML elements using Javascript.
    Create an HTML form with 5 radio buttons labeled: Date, Year, Month, Day of Week, Time. When a radio button is selected, it displays that information in a div tag.

    Working with Javascript

    Complete this assignment using Javascript and CSS to learn how to work in the HTML/CSS/Javascript environment.
    In this assignment, you will learn to manipulate the appearance and the contents of an HTML page using Javascript. This assignment uses the DOM Style Object to modify CSS properties with Javascript when events, such as OnClick and OnMouseOver and OnMouseOut occur. You may also want to look at Text input validation at w3.
    Read the following pages and use the advice in your JS coding.
    1. JS Style Guide
    2. JS Best Practices
    3. JS Mistakes
    4. JS Closures

    Light Box Exercise

    Create a webpage with 6 thumbnails of images. When a thumbnail is clicked, a lightbox should appear showing the larger version of the image.
    Use these resources, and the lesson taught in class, to complete this exercise:
    1. Read DOM EventListener
    2. Read Keyboard Events
    3. Keyboard Events Example
    Download Mouse Events skeleton code.
    1. KeyEvent task: As the user types, the equivalent dancing letters from the Dancing Cartoon Alphabet appear on the screen. Blue!
    2. MouseEvent task: when the user "drags and drops" the soccer ball, print the location (x,y) of the drop in a div tag.
    Resources
    Do the following:
    1. Read about setInterval and clearInterval
    2. Read How to Change an Object's Display
    3. Complete this exercise. DUE Tomorrow
    4. Do this tutorial on animation
    5. Create your own HTML document from the final animation in the previous tutorial. Due the day after tomorrow
      • Modify it so that IF the user clicks the cube, it stops moving.
      • Modify it so that IF the cube hits the bottom right corner of the yellow box, it reverses direction.
      • Modify it so that IF the cube hits the top left corner of the yellow box, it reverses direction.
    Following best programming practices can be difficult to do with a flexible language like JS. It can also make debugging very difficult. Run your Javascript through this website to ensure you are using best practices:
  • JS Hint
  • There are two options for this project. You will be assigned one of the following projects:
