title: How to modify the layout of jQuery UI autocomplete combobox
body: <p>I'm using the jQuery UI autocomplete combobox and want to modify the layout of the combobox, for example the height/width of the text field/toggle button and font size/color of the input text, but I do not know how to specify the class in CSS.</p>
  
  <p>For now, I'm only using <code>.ui-autocomplete-input</code> to change the height/width of the text field. Can anyone tell me how to modify other elements of the combobox?</p>
