Hi Kelly, we had fixed your issue, please have a look on your site.
Here is the process for the same
for this you need to use page/post custom field. On the custom field section of you pages you need to place following name on custom fields:
For header background you need to name custom field as
header_background
For header caption you need to name custom field as
header_caption
And your need to place your value correspondingly. On the value field of header_background you need to place URL of image and on header_caption you need to place content.
if you don’t want to place image on caption background you can use color as background ./ For this you can set background color from customizer. For this
Go to dasboard->appearance->customize->colours->Caption Header Background
Note: To use color as background you should remove custom fields: header_background
We hope this clarifies your queries, you can also see screnshot that may help you.
