There are two additional ways for custom HTML code inside Travelsavers templates (for admin users only):
To appear right before the main header starts
1- From the design section create a new page type: partial. You can use any title/name for your page but you must use as a permalink "_header".
2- Start adding you HTML code.
To appear right after the main footer ends
1- From the design section create a new page type: partial. You can use any title/name for your page but you must use as a permalink "_footer".
2- Start adding you HTML code.
Note: Travelsavers templates use the Bootstrap framework version 3.3.4, all the documentation is in the following link https://getbootstrap.com/docs/3.4/. You will find very helpful information for your new custom code.
