Creating a Range Slider

Step 1) Add HTML:

Example

Step 2) Add CSS:

Example

.slidecontainer {
width: 100%; /* Width of the outside container */
}

/* The slider itself */
.slider {
-webkit-appearance: none; /* Override default CSS styles */
appearance: none;
width: 100%; /* Full-width */
height: 25px; /* Specified height */
background: #d3d3d3; /* Grey background */
outline: none; /* Remove outline */
opacity: 0.7; /* Set transparency (for mouse-over effects on hover) */
-webkit-transition: .2s; /* 0.2 seconds transition on hover */
transition: opacity .2s;
}

/* Mouse-over effects */
.slider:hover {
opacity: 1; /* Fully shown on mouse-over */
}

/* The slider handle (use -webkit- (Chrome, Opera, Safari, Edge) and -moz- (Firefox) to override default look) */
.slider::-webkit-slider-thumb {
-webkit-appearance: none; /* Override default look */
appearance: none;
width: 25px; /* Set a specific slider handle width */
height: 25px; /* Slider handle height */
background: #04AA6D; /* Green background */
cursor: pointer; /* Cursor on hover */
}

.slider::-moz-range-thumb {
width: 25px; /* Set a specific slider handle width */
height: 25px; /* Slider handle height */
background: #04AA6D; /* Green background */
cursor: pointer; /* Cursor on hover */
}

Step 3) Add JavaScript:

Create a dynamic range slider to display the current value, with JavaScript:

Example

var slider = document.getElementById("myRange");
var output = document.getElementById("demo");
output.innerHTML = slider.value; // Display the default slider value

// Update the current slider value (each time you drag the slider handle)
slider.oninput = function() {
output.innerHTML = this.value;
}

Round Slider

To create a round slider handle, use the border-radius property. Tip: Set the height of the slider to a different value than the slider thumbs if you want unequal heights (15px vs. 25px in this example):

Example

.slider {
-webkit-appearance: none;
width: 100%;
height: 15px;
border-radius: 5px;
background: #d3d3d3;
outline: none;
opacity: 0.7;
  -webkit-transition: .2s;
  transition: opacity .2s;
}

.slider::-webkit-slider-thumb {
-webkit-appearance: none;
  appearance: none;
width: 25px;
height: 25px;
border-radius: 50%;
background: #04AA6D;
cursor: pointer;
}

.slider::-moz-range-thumb {
width: 25px;
height: 25px;
border-radius: 50%;
background: #04AA6D;
cursor: pointer;
}

Slider Icon/Image

To create a slider handle icon/image, use the background property and insert an image url:

Example

.slider::-webkit-slider-thumb {
  -webkit-appearance: none;
  appearance: none;
  width: 23px;
  height: 24px;
border: 0;
background: url('contrasticon.png');
cursor: pointer;
}

.slider::-moz-range-thumb {
width: 23px;
height: 25px;
border: 0;
background: url('contrasticon.png');
cursor: pointer;
}
