title: Change CSS only for mobile devices?
body: <p>I just finished creating my website but now I have found a failure. My problem is that my website looks totally nice on the PC. But if I go and look at it from my mobile phone, the spaces between certain images etc. are a great deal too much...</p>
  
  <p>So my question is, how can I create some CSS codes who are only affecting the mobile devices and maybe tablets?</p>
  
  <p>Is there a way?</p>
