Styling FAQ searchbar

Hello, I am trying to apply a border with some css to my premium searchbar addon to the plugin. However, when I click on the searchbar to type something in, the border dissappears. Is there a way I can have the border remain there while the user is typing? Here is my current css for the search bar

.ufaq-text-input {
background-color: white;
border-style: solid;
border-color: #f15a22;
border-width: 8px;
}
