Creating a Theme in CRX format: http://dev.chromium.org/developers/d...cuments/themes
List of images for CRX (only begins with IDR_THEME): http://src.chromium.org/viewvc/chrom..._resources.grd

To begin:
1. Create a folder, for example C:\MyTheme
2. Create a sub folder and add your images to it C:\MyTheme\Image
3. Create a file C:\MyTheme\manifest.json See example
4. Close all instances of Chrome.
5. Packaging an Extension http://dev.chromium.org/developers/d...ions/packaging
(for example, chrome.exe --pack-extension="C:\MyTheme")
6. It will creates 2 files: MyTheme.CRX and MyTheme.PEM

For future modifications, edit CRX:
chrome.exe --pack-extension="C:\MyTheme" --pack-extension-key="C:\MyTheme.pem"

NOTE:
in Mac OS X all buttons can only be modified in the Chrome Application Package. They are pdf files found in /Applications/Chrome.app/Contents/Resources/

In the finder right click on Chrome and select "show package contents"
then open the Contents folder, followed by the resource folder.

thanks for the additional info

subject changed to include Mac & Linux

Here's some other info a theme maker might like.
I fudged around to get these, so they might be wrong but I dont think so.

Colours (some colours are determined by other colours)

Status bar background = toolbar
Status bar text = ~half way between the tab_text and toolbar
Extension text (default) = bookmark text
Download bar text = bookmark text
Download bar background = toolbar
Download bar item = lighter version of toolbar
toolbar does the first line/frame around the page/bookmarks bar
Seperator Lines (the one between extensions or the bookmarks and Other bookmarks) - I know that toolbar determines the bottom gradient.....now whats the other colour


Toolbar Heights

0-25 Tab
26-60 Toolbar
61-86 Bookmark bar - be aware that 61 is still visible when the bar is collapsed

Extension bar seems to be getting its background from the toolbar image with 4.0.213.1, its so dam annoying....hopefully its just a bug.

If anyone else has some info like this Id love to hear it, especially if you know how to change the colour of those dam seperators.

Hello. It's very good tutorial. I made it. But now, i don't know how run this theme on Chrome(Mac OS X).

You just drag the crx file onto your chrome browser and accept the installation on the bottom left
