By default, Wijmo Input controls do not get highlighted when they come into focus. We can change this by adding some CSS to the control's class.
1. Add a class to the control
2. Assign border style to the CSS class on focus-within
First, you'll need to add a class to the control so that we can append CSS to it when it goes into focus
Next, CSS will need to be added to place a border around the control when it gains focus.
Focus-within is used because the textbox that you can enter information into is another element within the actual control. Focus-within will apply the CSS when an element within the class receives focus.
