title: CSS get text to stand still
body: <p>I have an countdown page, that counts down the time to a specific date. Now, every time the milliseconds gets only 2 or 1 decimal, the whole text moves itself (looks like flickering). What would I need to change to get the text to stand absolutely still?</p>
  
  <p>I made a GIF of how it looks.
