title: Speed up blink timer using CSS3 animation
body: <p>I'm building a quiz app with a timer (from 10s - 0s). When the amount of time is approaching the 0s, I want my text to blink faster and faster. When the timer is around 10s I want a transition time of 2 seconds decreasing when there is less time left.</p>
  <h3>Is there a way to fix this with CSS3?</h3>
