Infinite Marquee responsive no gap

Issue

I have a problem with this code. I want to apply a marquee effect to this words with continues animation. In my result, at the 100% Keyframe, the animation return to 0 and the effect is orrible! I want animation to be fully responsive. Thank u very much!

With this video you can see the error -> VIDEO

var elements = $('ul.tithome li').length;

for(var i=0;i < elements; i++){
 $(".tithome").clone().prependTo( ".scorri" );
};

var liEle = [];
var liEle = $(".tithome li");

.cont{
  width: 100%;
  overflow: hidden;
}

.scorri{
  position:relative;
  display: flex;
  width: 100%;
  animation-name: marquee;
  animation-duration: 20s;
  animation-iteration-count: infinite;
  animation-timing-function: linear;
  justify-content: space-between;
}

.tithome{
  display: contents;
}

.tithome li{
  width: fit-content;
  display: inline-block;
  list-style: none;
  padding-right: 30px;
  font-size: 40px;
}

@keyframes marquee {
  0% { left: 0; }
  100% {left: -88.79%;}
}

<div class="cont">
<div class="scorri">
  <ul class="tithome">

Solution

You can animate a transform property instead of left:

var elements = $('ul.tithome li').length;

for(var i=0;i < elements; i++){
 $(".tithome").clone().prependTo( ".scorri" );
};

var liEle = [];
var liEle = $(".tithome li");

.cont{
    width: 100%;
    overflow: hidden;
}

.scorri{
    position: relative;
    display: flex;
    width: 100%;
    justify-content: space-between;
}

.tithome{
    animation-name: marquee;
    animation-duration: 5s;
    animation-iteration-count: infinite;
    animation-timing-function: linear;
    flex-shrink: 0;
}

.tithome li{
    width: fit-content;
    display: inline-block;
    list-style: none;
    padding-right: 30px;
    font-size: 40px;
}

@keyframes marquee {
    0% { transform: translateX(0); }
    100% { transform: translateX(-100%); }
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="cont">
<div class="scorri">
  <ul class="tithome">
    <li>Governance</li>
    <li>HR</li>
    <li>Sales</li>
  </ul>
</div>
</div>
