A Color Chooser template uses CSS color values, combined with transparent overlay images, to determine its color and style. Therefore, you can change the entire color scheme via the Gantry Administrator. The available options are outlined below:
With Gantry, the ability to assign a certain style to an individual page has never been easier and/or more efficient. Just follow these simple steps:
There are 80 module positions. If no module is published to a position, it will not appear, collapsing the entire area.
Non-Standard Elements
There are non-standard elements that are injected into the template grid structure when enabled via the template parameter, such as the logo into header-a. These features stack vertically with any modules published to that position.
You can change the positions of these elements at Extensions → Template Manager → (J15) rt_halcyon_j15 or (J17) rt_halcyon
Layout Control
Control all modules positions with Gantry, in terms of widths within the module row, and left/right/middle placement for the mainbody/sidebar area.


Preview Positions
View all module positions live by appending ?tp=1 or &tp=1 to the end of your URL such as http://yoursite.com/index.php?tp=1.
