How to create a marquee using CSS or Javascript

I need to create two marquees (one with a repeating image and one with repeating links) that span the browser window at any size; the marquee items need to be displayed from the start and not take a few seconds to appear on screen and each of them need to be about 20px/30px apart. When a user hovers over it, the marquee needs to stop moving across the page.

I'm creating a website for a client and on one page we've decided on having a marquee to display the logo and on another, a marquee to display links to the client's social media. I'm unsure of how to calculate the necessary duration of the animation, based off the size of the text or image to make it appear infinite. I've looked into and tried out CSS options and I've asked around only to find that Javascript is usually recommended for this. I've just begun diving into Javascript, so I'm pretty clueless with where to start on this project. This is actually pretty similar to what I need: https://stackoverflow.com/a/45103608/11623961. This is an example of what I'm trying to achieve: http://maxsiedentopf.com/work-2 (only the one at the bottom, but with no overlap from the left side; simply moving from left to right). This is what I was trying to use to achieve the desired effect: https://codepen.io/jamesbarnett/pen/kfmKa.

body { 
  margin: 0;
  font-family: "UniversLTPro-Ex";
  font-size: 30px;
}

a {
    text-decoration: none;
    color: #000;
}

.marquee {
  height: 35px;
  width: 100%;

  overflow: hidden;
  position: relative;
  background-color: #e9e5fb;  
  border-top: 1px solid black;
  border-bottom: 1px solid black;
  padding: 8px 0 4px 0;
}

.marquee div {
  display: inline-block;
  width: 300%;
  height: 40px;

  position: absolute;
  overflow: hidden;

  animation: marquee 12s linear infinite;
}

.marquee span {
  float: left;
  width: 25%;
}

@keyframes marquee {
  0% { left: 0; }
  100% { left: -150%; }
}

        <div class="marquee">
            <div>
                <span><a href="#">twitter</a></span>
                <span><a href="#">instagram</a></span> 
                <span><a href="#">pinterest</a></span>
                <span><a href="#">spotify</a></span> 
                <span><a href="#">magazine</a></span>
            </div>
        </div>

Obviously, there are a lot of problems with what I tried to do. The marquee does not appear infinite, I have not figured out how to pause on hover, the items are too far apart. Any help would be greatly appreciated. Thank you!

Solution

Here are a few ways you can achieve the result, you can choose the one u like the best.

HTML marquee tag
CSS animation and text-indent
CSS animation and position relative
JS vanilla (no libs)
JS Jquery animate

/* Vanilla JS */

var rightJS = {
  init: function(){
    rightJS.Tags = document.querySelectorAll('.rightJS');
    for(var i = 0; i < rightJS.Tags.length; i++){
      rightJS.Tags[i].style.overflow = 'hidden';
    }
    rightJS.Tags = document.querySelectorAll('.rightJS div');
    for(var i = 0; i < rightJS.Tags.length; i++){
      rightJS.Tags[i].style.position = 'relative';
      rightJS.Tags[i].style.right = '-'+rightJS.Tags[i].parentElement.offsetWidth+'px';
    }
    rightJS.loop();
  },
  loop: function(){
    for(var i = 0; i < rightJS.Tags.length; i++){
      var x = parseFloat(rightJS.Tags[i].style.right);
      x ++;
      var W = rightJS.Tags[i].parentElement.offsetWidth;
      var w = rightJS.Tags[i].offsetWidth;
      if((x/100) * W  > w) x = -W;
      if (rightJS.Tags[i].parentElement.parentElement.querySelector(':hover') !== rightJS.Tags[i].parentElement) rightJS.Tags[i].style.right = x + 'px';
    } 
    requestAnimationFrame(this.loop.bind(this));
  }
};
window.addEventListener('load',rightJS.init);

/* JQUERY */

$(function(){
  var rightJQ = {
    init: function(){
      $('.rightJQ').css({
        overflow: 'hidden'
      });
      $('.rightJQ').on('mouseover',function(){
        $('div', this).stop();
      });
      $('.rightJQ').on('mouseout',function(){
        $('div', this).animate({
          right: '100%'
        }, 14000, 'linear' );
      });
      rightJQ.loop();
    },
    loop: function(){
      $('.rightJQ div').css({
        position: 'relative',
        right: '-100%'
      }).animate({
        right: '100%'
      }, 14000, 'linear', rightJQ.loop);
    }
  };
  rightJQ.init();
});

.rightTI { background: #ff002b;
  white-space: nowrap; 
  overflow: hidden;

}
@-webkit-keyframes marquee {
  0% {text-indent: 100%;}
  100% {text-indent: -100%;}
}

.rightCSS {

} 
.rightCSS div {
  position: relative;
  animation: CSSright linear 18s infinite;
} 
@keyframes CSSright {
  0% { right: -100% }
  100% { right: 100% }
}
.rightCSS:hover div {
  animation-play-state: paused;
}

.rightJS { background: #ffa900; }

.rightJQ { background: #00a753; }

.li {
