Value:Creating a Range Slider
Step 1) Add HTML:
Example
<div class="slidecontainer">
<input type="range" min="1" max="100"
value="50" class="slider" id="myRange">
</div>
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: #4CAF50; /* 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: #4CAF50; /* 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: #4CAF50;
cursor: pointer;
}
.slider::-moz-range-thumb
{
width: 25px;
height: 25px;
border-radius: 50%;
background: #4CAF50;
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;
}
