Hi Phil!
Instead of changing the plugin files, I rather suggest using custom CSS codes, as it will last beyond an update.
I will try to construct the custom CSS codes for each case.
1. Custom fonts for results:
[html]div[id*=’ajaxsearchprores’],
div[id*=’ajaxsearchprores’] * {
font-family: whatever-font !important;
}[/html]
Replace the whatever-font with the one you need, it will apply on all of the elements on the results box.
2. There is actually an option for that: http://i.imgur.com/ry6Z9Y5.png
3. The close icon is not changeable, but you can change it’s color with a custom CSS:
[html].probox .proclose svg {
background: red !important;
}[/html]
4. It’s calculated automatically, but with a top margin you can “cheat” the distance, for example to bring it closer:
[html]div[id*=’ajaxsearchprores’] {
margin-top: -40px !important;
}[/html]
I hope these help!
