Before we get started:

Here is the link for the template that i used for the layout design https://getbootstrap.com/.

Creating The Interface

This is where we will create a simple interface for our application. This code will only display the html object and html slider. To create this simply copy and write it into your text editor, then save it as index.html.

<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
		<link rel="stylesheet" type="text/css" href="css/bootstrap.css" />
	</head>
<body>
	<nav class="navbar navbar-default">
		<div class="container-fluid">
			<a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
		</div>
	</nav>
	<div class="col-md-3"></div>
	<div class="col-md-6 well">
		<h3 class="text-primary">How to Adjust Object Radius using Slider</h3>
		<hr style="border-top:1px dotted #ccc;"/>
		<div class="col-md-6">
			<div id="target" style="width:100%; height:300px; background-color:blue; border:2px solid #000;"></div>
		</div>
		<div class="col-md-3">
			<div class="form-inline">
				<input type="text" id="slide_text" class="form-control" value="0" size="4" readonly="readonly"/> 
			</div>
			<div class="form-group">
				<label>Set Value</label>
				<input type="range" oninput="adjustRadius(this);" value="0" min="0" max="150"/> 
			</div>
		</div>
	</div>
<script src="script.js"></script>	
</body>	
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will allow you to dynamically adjust the radius of an object. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function adjustRadius(slider){
	var input=document.getElementById("slide_text");
 
	input.value=slider.value;
 
	document.getElementById("target").style.borderRadius=slider.value+"px";
}

In the code above we just simply create one method called adjustRadius(). this function will dynamically adjust the radius of an object. The function will dynamically adjust object radius by tweaking the object css border radius property.
