title: Is it possible to add a transition (like in CSS) in Javascript?
body: <p>I have a Javascript code that shows a tooltip when hovering over an HTML element. Now I want to give this element a latency of about 6 milliseconds. In CSS it is very easy with the transition command. However, I did not find a transition style command in Javascript. Is there a solution or do I have to change to another programming language?</p>
  
  <p>Javascript code:</p>
  
  <pre><code>var bghtooltipin = document.getElementById('bgh-tooltipin1');
  var bghtooltipout = document.getElementById('bgh-tooltipout1');
  bghtooltipin.addEventListener('mouseover', bghtooltipinmouseOver);
  bghtooltipin.addEventListener('mouseout', bghtooltipoutmouseOut);
  
  function bghtooltipinmouseOver() {
    bghtooltipout.innerHTML = 'Go to Login';
    bghtooltipout.style.color = "white";
    bghtooltipout.style.top = "0";
  }
  
  function bghtooltipoutmouseOut() {
    bghtooltipout.innerHTML = ' ';
    bghtooltipout.style.top = "-99999px"
  }
  </code></pre>
