Many web designers are moving away from the use of the standard centered, fixed-width CSS layout that generates a strong vertical feel as its content spills down the page when the visitor scrolls. These designers are instead following a popular technique that our Community MX colleague Zoe Gillenwater calls the "horizontal band" layout.
To tone down the vertical feel of traditional CSS layouts, the horizontal band layout uses background colors or images applied to stacked div elements that stretch across the entire width of the browser window. The following sites provide good examples of this technique:
Basic horizontal band layouts use horizontal bands just for the header and footer, sometimes including a navigation bar. The content area may or may not have a background color behind it. The footers are often very deep, prompting designers to call them fat footers or big foot. It is such a layout that we will create in this series of tutorials.
Additionally, when we recreate the layout in Dreamweaver, we will jazz it up with two Spry widgets: Accordion Panels and Tabbed Panels.
Figure 1 shows a preview of the finished comp for the fictitious blog, Blimey, that this tutorial helps you create.

To get started, launch Fireworks and create a new canvas (see Figure 2):

The first step is to create the horizontal bands that will make up the design's four modules. These modules will be coded with CSS in a later part of this tutorial.
To create the first band, draw a rectangle at the top of the canvas and fine-tune it with the following settings in the Property inspector (see Figure 3):

Be sure to give each object you create a meaningful name so that you can easily recognize it as the list of objects and layers grows. Name this rectangle header background.
Next, add the second band that will form the background for the Blimey logo (see Figure 4):

Note: To create a comp that is properly aligned in the XHTML document, use the Property inspector to set coordinates precisely, rather than placing and sizing elements by clicking and dragging.
The content portion of the layout will not have a color band behind it, but will instead have a border to set it off from the other portions of the page.
In the Property inspector, set the following attributes (see Figure 5):

Clone the rectangle and make the following changes in the Property inspector (see Figure 6):

Figure 7 shows the completed content border.

The final band will serve as the background for the footer. Horizontal band layouts often have deep footers that provide more than just a copyright notice or address. These footers can have complex layouts of their own, with columns and auxiliary content that maximizes the page real estate.
Name this object big foot background.

The bands are now complete. Your PNG should look like Figure 9.

Before you go any further, organize these components onto new layers to separate them from each other and make it easier to keep track of where to make modifications:
Drag the appropriate objects into each layer (see Figure 10).

Figure 10. Organizing with layers
Lock each layer by clicking the box to the right of the eye icon. This makes it impossible for you to accidentally delete or change anything in each horizontal band background as you add other objects to its layer.
