Hi Steve,
I found this custom CSS rule in the header style CSS file:
[html]input, textarea, select, input, textarea, select {
border:1px solid #b3b3b3!important;
}
input:focus, textarea:focus, select:focus, input:active, textarea:active, select:active {
border: 1px solid #474747 !important;
background-color: white !important;
outline: none;
box-shadow:none !important;
-webkit-border-radius: 0px;
-moz-border-radius: 0px;
border-radius: 0px;
}[/html]
This overrides all borders on every input/select/textarea fields on the page. You can leave them as they are, just add this custom CSS rule as well, so it overrides the input fields in the search box with no borders:
[html].asp_w input, .asp_w textarea, .asp_w select,
.asp_w input:focus, .asp_w textarea:focus, .asp_w select:focus {
border: none !important;
}[/html]
