title: Rendering empty space in React
body: <p>Please see the snippet below. I am trying to render a blinking text, that, when it does not appear, leaves an empty space. However, React is just removing the element all together it seems. How do I properly render an empty space in React? Tried to do some searching and testing with various spans but still didn't get anywhere. Thanks.</p>
