The Spanish homepage uses the "Spanish Home" template. This template works the same as your main homepage, but please note the following: 

• Button links: this is managed under content > link lists > Footer Social Links Spanish
• For the "Footer Featured" sections, you can assign 3 sections, rotator, etc. the same as the main homepage

There are two subpage templates available to display for the Spanish subsite, which will display the separate logo, header, footer, etc.  These two templates work the same as your default subpage templates in regards to the header and section options. 

These are labeled:

• Spanish - Page
• Spanish - Subpage Full
