For the first part, we're going to create the basic layout for the website.
First of all create a new Flash document with the settings shown below. For the background color I've used #55666D
We're going to create a rectangle for the background of the site. Set the stroke color (circled in blue), using the icon circled in red. This will prevent there from being a border around the rectangle.
Set the fill color (circled in blue) to white (circled in red).
Choose the rectangle tool (circled in red) and create a rectangle with the settings shown below in the properties panel. The stage has been zoomed out to 50%.
