Theme Key

Webinar: Mobile Optimized and Responsive Websites [1]

You can change your site to a different Theme, that only you can see when logged into your account. This allows you to prepare a different Theme, while still displaying your current Theme to customers.

CHOOSE THEMES

Navigate to: Appearance (Admin bar)

Scroll to ‘Disabled Themes’ and select ‘Enable’ on any you may want to work with.

CONFIGURE THE THEME KEY TOOL

Navigate to: Configuration > User Interface > Themekey > Settings > User Interface

Expand ‘Selectable Themes’: This will open a list of all the Themes that have been enabled, with a ‘Selected’ checkbox to the right of each one.
Check each Theme that you want to be available in the Themekey tool
Save Configuration

SET A THEME TO DISPLAY FOR YOUR ACCOUNT

Navigate to: Your account page by clicking on your username (located in the Admin Bar)

Select ‘Edit’
Expand ‘Theme Configuration’
Select any one Theme to appear for you, while you're logged into your account.
Save

Once you select a Theme and save your account settings, you will see the site in the selected Theme when you visit any customer-facing pages. This will allow you to configure Blocks, change colors (if the Theme allows it), and generally make sure the Theme looks just as you want.

The changes you make under the selected theme will remain and you can resume working on it at any time and you can switch between working on the theme and revert to viewing the default again.
