How to customize the look and feel of a Sunshine Theme
Go to Sunshine > Settings > General tab. Select “Default Sunshine Theme” if not already select.
Below, there is an option to select your logo file. First, click the link below the drop down for Media Gallery or find the Media tab in your WordPress administration.
Upload your logo file. Recommended size is no wider than 170px, as a .png file and with a transparent background.
Head back to the Sunshine > Settings > General tab and select the file you just uploaded from the drop down menu.
Find the Theme tab in the Sunshine Settings area. Select colors, background images (uploaded the same way your logo was previously) and other various styling options.
For Google Web fonts, find the font you want to use, copy the name exactly as it appears on the site and paste it into the text field.
Each of the Sunshine themes may have slightly different options to configure.
