How can I adjust the width of a handle/thumb for NoUiSlider?

Looking to adjust the width of a NoUiSlider using CSS:

.noUi-horizontal .noUi-handle {
    width:8px;
    height:25px;
    left: 0px;
    top: -8px;
    border: 0px solid #000000;
    border-radius: 0px;
    background: #000;
    cursor: default;
    box-shadow: none; /*inset 0 0 1px #FFF, inset 0 1px 7px #EBEBEB, 0 3px 6px -3px #BBB;*/ }

.noUi-handle {
     left:0px; }

.noUi-active {
    box-shadow: none /*inset 0 0 1px #FFF, inset 0 1px 7px #DDD, 0 3px 6px -3px #BBB;*/ }

.noUi-handle:before, .noUi-handle:after {
    content: "";
    display: block;
    position: absolute;
    height: 14px;
    width: 0px;
    background: #000000;
    left: 14px;
    top: 6px; }

.noUi-handle:after {
    left: 0px; }

Despite achieving the slim handle desired, it's causing an issue where the handle no longer conceals the color transition between white and green in the track. Instead, the transition is exposed when adjusting the handle width.

Answer №1

Dealing with nouislider can be tricky, especially when you want to create a comprehensive solution. I have put together an example below based on lg102's input, and made some adjustments to enhance clarity. I had to use !important in the CSS to ensure certain properties were applied.

An example like this would be beneficial to include in nouislider's official documentation, which is already much more informative compared to other JavaScript library docs.

<head>
   <script type="text/javascript" src="nouislider.js"></script> 
   <link href="nouislider.css" rel="stylesheet">
   <script>
     function init(){
        noUiSlider.create(slider_id, {
                start: [25, 75],
                connect: [false, true, false],
                range: {
                    'min': 0, 
                    'max': 100
                }
            })
      }
   </script>
   <style>
     .noUi-handle {
        width: 10px !important;
        right: -5px !important; /*  must be (width / 2) * -1 */
        background: #AA00AA;
     }
   </style>
</head>
<body onload="init()" >
<h3>slide test1</h3>
<div id="slider_id" style="width:300px;height:20px;"/>
</body>

Answer №2

Adjusting the left value for the .noUi-handle to 0, as shown below:

.noUi-handle {
    width: 34px;
    height: 28px;
    left: auto;
    right: -17px; /* The 17 here is half of the 34 width. The - pulls it in the other direction */
    top: -6px;
}

If you are changing the width to 8, then the right (or left) should be set to -4 (which is half of 8).

The minimal changes required include adding:

width: 10px;
right: -5px;

You can experiment with this modification by accessing the documentation link provided below:
