Learn how to build a slider from scratch using pure JavaScript! Includes a step-by-step example.

Making a Slider on Pure JavaScript

Making a slider on pure JavaScript is a straightforward process. The basic structure of a slider consists of an HTML element, a JavaScript script, and a CSS style sheet. The HTML element is the container for the slider, while the JavaScript script controls the behavior of the slider. The CSS style sheet defines the look and feel of the slider.

Let's start with the HTML element. The HTML element should be a <div> element with an id attribute. This id attribute will be used to reference the slider in the JavaScript script and CSS style sheet. Here's an example of an HTML element for a slider:

<div id="slider"></div>

Now, let's move on to the JavaScript script. The JavaScript script will be responsible for controlling the behavior of the slider. The script should contain functions for setting the slider's position, getting the slider's position, and updating the slider's position. Here's an example of a JavaScript script for a slider:

// Set the slider's position
function setSliderPosition(position) {
  // Code for setting the slider's position
}

// Get the slider's position
function getSliderPosition() {
  // Code for getting the slider's position
}

// Update the slider's position
function updateSliderPosition() {
  // Code for updating the slider's position
}

Finally, let's move on to the CSS style sheet. The CSS style sheet will be responsible for defining the look and feel of the slider. The style sheet should contain rules for styling the slider container, the slider bar, and the slider handle. Here's an example of a CSS style sheet for a slider:

/* Slider container */
#slider {
  width: 300px;
  height: 30px;
  background-color: #ccc;
  border-radius: 5px;
  overflow: hidden;
}

/* Slider bar */
#slider .bar {
  width: 100%;
  height: 100%;
  background-color: #999;
}

/* Slider handle */
#slider .handle {
  width: 30px;
  height: 30px;
  background-color: #666;
  position: relative;
  left: 0;
  top: 0;
  cursor: pointer;
}

That's it! With the HTML element, JavaScript script, and CSS style sheet in place, you now have a functional slider on pure JavaScript.
