<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8"/>
                <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://www.sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="container-fluid">   
                <div class="row">
                        <div class="col-md-3"></div>
                        <div class="col-md-6 well">
                                <h3 class="text-primary">How to Change Color of Element Dynamically</h3>
                                <hr style="border-top: 1px SOLID #8c8b8b;"/>
                                <div class="col-md-3" style="padding:10px;">
                                        <button id="red" onclick="changeColor(this.id)">Red</button>
                                        <br /><br />
                                        <button id="blue" onclick="changeColor(this.id)">Blue</button>
                                        <br /><br />
                                        <button id="green" onclick="changeColor(this.id)">Green</button>
                                        <br /><br />
                                        <button id="yellow" onclick="changeColor(this.id)">Yellow</button>
                                        <br /><br />
                                        <button id="orange" onclick="changeColor(this.id)">Orange</button>
                                        <br /><br />
                                        <button id="purple" onclick="changeColor(this.id)">Purple</button>
                                        <br /><br />
                                        <button id="pink" onclick="changeColor(this.id)">Pink</button>
                                        <br /><br />
                                        <button id="black" onclick="changeColor(this.id)">Black</button>
                                </div>
                                <div class="col-md-6" id="box" style="border:1px solid #000; height:280px;">
                                        
                                </div>
                                <div class="col-md-3">
                                        
                                </div>
                        </div>
                </div>
        </div>  
</body>
<script src="script.js"></script>
</html>

Creating JavaScript Function

This is where the main function of the application is. This code will only cover the changing of element color. To do this just copy and write these block of codes inside the text editor and save it as script.js.

function changeColor(id){
        document.getElementById("box").style.backgroundColor=id;
}

In this code we only create a method called changeColor(), and putting the button id in order to get the value. We then targeted the element id and use style function to get the attribute background color, we apply the button value to change the element color.
