two circles should follow the cursor – one small and one big (with delay)

Question

I have seen this tendency on some websites now, where the default cursor is replaced with a new cursor – in many cases circles

These cursors are interactive – with interactive i mean when hovering an a-tag it changes size and color.

On this website: https://en.leviev-group.com/ you can see the effect on the cursor that I want.

I have tried to make a Pen, but it isn't working properly: https://codepen.io/anon/pen/VQwdBv?q=cursor&limit=all&type=type-pens

<div id="cursor">
<div id="circle-big"></div>
<div id="circle"></div>
</div>

I would like the circle in the middle to be the cursor and the big circle around to follow the cursor with delay. When hovering a-tags it should wrap around the a-tag, similar to the example on the website. If possible made with javascript and css

How is this possible?

You are almost good, simply make both element behave the same and by adding the transition on the small one you will make it slower and create the follow effect.

$('body').mouseover(function() {
  $(this).css({
    cursor: 'none'
  });
});

$(document).on('mousemove', function(e) {
  $('#circle-big').css({
    left: e.pageX,
    top: e.pageY
  });
  $('#circle').css({
    left: e.pageX,
    top: e.pageY
  });

});

#circle-big {
  display: block;
  position: absolute;
  margin-top: -30px;
  margin-left: -30px;
  width: 60px;
  height: 60px;
  z-index: -1;
  text-align: center;
  border: 2px solid red;
  border-radius: 50%;
}

#circle {
  display: block;
  position: absolute;
  margin: auto;
  transition: all 1s linear;
  width: 15px;
  height: 15px;
  margin-top: -7.5px;
  margin-left: -7.5px;
  z-index: -1;
  background-color: rgba(255, 0, 0, 0.5);
  border-radius: 50%;
  box-shadow: 0px 0px 10px 4px rgba(255, 255, 255, 1);
}

a {
  font-size: 26px;
  text-align: center;
  margin: 100px auto;
  display: block;
}

a:hover {
  font-size: 30px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cursor">
  <div id="circle-big"></div>
  <div id="circle"></div>
</div>

<a>link</a>

Or change the transition if you want the bigger one to follow the small one:

$('body').mouseover(function() {
  $(this).css({
    cursor: 'none'
  });
});

$(document).on('mousemove', function(e) {
  $('#circle-big').css({
    left: e.pageX,
    top: e.pageY
  });
  $('#circle').css({
    left: e.pageX,
    top: e.pageY
  });

});

#circle-big {
  display: block;
  position: absolute;
  margin-top: -30px;
  margin-left: -30px;
  transition: all 1s linear;
  width: 60px;
  height: 60px;
  z-index: -1;
  text-align: center;
  border: 2px solid red;
  border-radius: 50%;
}

#circle {
  display: block;
  position: absolute;
  margin: auto;
  width: 15px;
  height: 15px;
  margin-top: -7.5px;
  margin-left: -7.5px;
  z-index: -1;
  background-color: rgba(255, 0, 0, 0.5);
  border-radius: 50%;
  box-shadow: 0px 0px 10px 4px rgba(255, 255, 255, 1);
}

a {
  font-size: 26px;
  text-align: center;
  margin: 100px auto;
  display: block;
}

a:hover {
  font-size: 30px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cursor">
  <div id="circle-big"></div>
  <div id="circle"></div>
</div>

<a>link</a>

UPDATE

You may consider event on links tag if you want to change the cursor when hovering links.

Here is a simple example:

$('body').mouseover(function() {
  $(this).css({
    cursor: 'none'
  });
});

$(document).on('mousemove', function(e) {
  $('#circle-big').css({
    left: e.pageX,
    top: e.pageY
  });
  $('#circle').css({
    left: e.pageX,
    top: e.pageY
  });
});
$('a').mouseover(function() {
  $('#cursor').addClass('on-link');
})
$('a').mouseout(function() {
  $('#cursor').removeClass('on-link');
})

#circle-big {
  display: block;
  position: absolute;
  margin-top: -30px;
  margin-left: -30px;
  transition: all 1s linear;
  width: 60px;
  height: 60px;
  z-index: -1;
  text-align: center;
  border: 2px solid red;
  border-radius: 50%;
}

#circle {
  display: block;
  position: absolute;
  margin: auto;
  width: 15px;
  height: 15px;
  margin-top: -7.5px;
  margin-left: -7.5px;
  background-color: rgba(255, 0, 0, 0.5);
  border-radius: 50%;
  z-index: -1;
  box-shadow: 0px 0px 10px 4px rgba(255, 255, 255, 1);
}

#cursor.on-link #circle-big {
  border: 2px solid blue;
}

a {
  font-size: 26px;
  text-align: center;
  margin: 100px auto;
  display: block;
}

a:hover {
  font-size: 30px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="cursor">
  <div id="circle-big"></div>
  <div id="circle"></div>
</div>

<a>link</a>
