The Silk theme and its variations are available from Josh Lockhart.

The instructions are as follows:
Silk's banner height options

height

Make your Bannerzest banner 40px narrower that the width of your theme. For example, if you've chose the 840 px width for your Rapidweaver project, make the Bannerzest banner 800 px wide (840 - 40 = 800) This is for this theme only. Other themes use the entire page width. The height of your banner will depend on the height that you've selected within the theme. (see Banner height at right)


Publish the site and reveal the HTML

Publish the Bannerzest theme to its place on your server and select "Show HTML" (see Publish at right)




Copy Bannerzest's code to the clipboard

When you click this button, you'll be presented with another window (see Copy at right)






Use Textwrangler to open index.html
TextWrangler

Now we have the necessary code copied to our clipboard. The final step is to open the theme's index.html file with the text editor you've selected and paste the code in the correct location. To open this file, right click the theme in Rapidweaver's theme drawer, choose "Reveal Theme Contents In Finder...". This will present you with a folder called "Contents". Open it and you will find the index.html file. Right click on this file and navigate to your chosen text editor application. In this example I chose TextWrangler. (see Textwrangler at right)



Here's where you paste the code!!
Paste here


Scroll through the code until you find a place that matches that shown in the photo (see Paste here at right) The code you copied from Bannerzest is still on your clipboard. You want to paste it in the right spot. Place your cursor right before the div with the id of "breadcrumbsBackground". Hit the enter key once to create a blank line which will move "breadcrumbsBackground" down a space. Move your cursor back up to the blank space you just created and paste in the code from Bannerzest by either choosing edit>Paste from TextWrangler's menu or simply by pressing the Apple-v key combination (command-v). Now that your code is inserted, save the file and view the results.

Remember, when you use this technique and publish your site, send me a link so I can put your site in the showcase!

Pretty snazzy, huh?
