Creating a dynamic Tank level/meter using html and css

Question

I am currently having problems creating a \'tank gauging system\' within my project. I am using MVC and the by using the following markup, I have achieved this:

Answer 1

I think I have achieved the requested, by playing around with positioning (absolute will respect the parent block element with position relative or absolute - so it is easier to just use bottom: 0 - also that makes the div to increase its height from botton to top automatically)

html

css file:

.tk {
    position:relative;
    width:40%; 
    height:100px;
    padding-top:40px;
    margin: 0 auto;
    background:rgba(56,56,56,0.8);
    border-radius: 100%/40px;
    border-bottom:3px solid #000;
    text-align:center;
    z-index:1;
    overflow:hidden;
    }
    
.lq {
  position: absolute;
  background:rgba(128,128,128,0.99);
  width: 100%;
  height:0;
  bottom: 0;
  border-radius:100%/40px;
  border-bottom:3px solid #000;
}


.ring {
  position: absolute;
  border-radius:100%;
  top: 0;
  width: 100%;
  height:40%;
  content: '';
  border:1px solid #000;
}
    
.text {
  display: block;
  position:absolute;
  top: 45%;
  left: 45%;
  z-index: 1;
}

js file (with jquery):

var quantity = amount;
$(this).find('.lq').animate({'height' : parseInt(amount) + '%'},1000);
  $('.ring').css({height : 100 - amount + 10 + '%'});
  $('.text').text(quantity  + '%'); 
  });
  $('.text').each(function(){
    var $this = $(this);
     jQuery({ Counter: 0 }).animate({ Counter: $this.text() }, {
    duration: 1000,
    easing: 'swing',
    step: function () {
      $this.text(Math.ceil(this.Counter) + "%");
    }
  });
  });
});
