Blob Maker Step By Step Using HTML, CSS & JavaScript

Hello everyone. Welcome to today’s tutorial on Codewithrandom. We’ll learn how to make a blob maker which is a design of a pie we’ll just have to set the height and width it will give us the syntax which should be added in the CSS code of the respective project to add that shape. In Today’s session, We will use HTML, CSS, and JavaScript to complete this Project.

The HTML (Hypertext Markup Language) will help us to create the structure for the list with some necessary attributes and elements to make Blob Maker.

Then we will use CSS (Cascading Stylesheet) which will help us to style or design the project with suitable padding and alignment in the Blob Maker project.

At last we will use JS (JavaScript) which will add a logic to make the Blob Maker project responsive from the user end.

Using CSS we present Blob Maker Step By Step Using HTML, CSS, & JavaScript projects with source code available for you to copy and paste directly into your own project.

I hope you have got an idea about the project.

HTML Code for Blob Maker

<html lang="en">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Blob Maker</title>
    <!-- Google Font -->
    <link href=";500&display=swap" rel="stylesheet">
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css">

        <div class="output">
            <div id="blob"></div>
        <div class="dimensions">
                <label for="blob-height">
                <input type="number" value="200" id="blob-height">
                <label for="blob-width">
                <input type="number" value="200" id="blob-width">
        <div class="sliders">
            <input type="range" value="30">
            <input type="range" value="80">
            <input type="range" value="60">
            <input type="range" value="40">
        <input type="text" id="css-code" readonly>
        <button id="copy">Copy</button>
    <script src="script.js"></script>

First, we’ll start with creating the structure of the Blob Maker project for that as you can see in the above code we have used all the necessary elements & attributes. Let us know code the CSS part to add styling and aligned the tags.

CSS Code for Blob Maker

    padding: 0;
    margin: 0;
    box-sizing: border-box;
    outline: none;
    font-family: "Roboto Mono",monospace;
    font-weight: 400;
    color: #010120;
    background-color: #008dff;
    background-color: #ffffff;
    width: 45%;
    min-width: 550px;
    padding: 30px;
    position: absolute;
    transform: translate(-50%,-50%);
    top: 50%;
    left: 50%;
    border-radius: 8px;
    background-color: #eef3f8;
    width: 100%;
    min-height: 250px;
    padding: 20px 0;
    overflow: hidden;
    border-radius: 5px;
    position: relative;
    display: grid;
    place-items: center;
    height: 300px;
    width: 300px;
    background: linear-gradient(
    box-shadow: 15px 20px 30px rgba(0,0,0,0.15);
    display: flex;
    justify-content: space-around;
    width: 100%;
    margin: 20px 0 40px 0;
    font-weight: 500;
    height: 40px;
    width: 80px;
    padding: 10px;
    margin-top: 5px;
    border: 1px solid #a0a0b0;
    border-radius: 3px;
    background-color: #f1f5fa;
    border-color: #025eaa;
    color: #025eaa;
    width: 100%;
    display: grid;
    grid-template-columns: 1fr 1fr;
    grid-gap: 20px;
    width: 82%;
    margin-top: 50px;
    padding: 10px;
    font-size: 12px;
    border: none;
    background-color: #f1eff9;
    border-radius: 3px;
    width: 12%;
    margin-left: 4%;
    padding: 10px 0;
    background-color: #0075ff;
    border: none;
    cursor: pointer;
    border-radius: 3px;
    color: #ffffff;
    font-size: 12px;

Second, comes the CSS code which we have styled for the structure we have padded as well as aligned the Blob Maker project so that it is properly situated and doesn’t get messy with suitable CSS elements. Now let’s code the JavaScript part to make it responsive.

Create Horizontal Flip Image Using Simple HTML And CSS

JavaScript Code for Blob Maker

let outputCode = document.getElementById("css-code");

let sliders = document.querySelectorAll("input[type='range']");

let inputs = document.querySelectorAll("input[type='number']");

function createBlob(){
    let radiusOne = sliders[0].value;
    let radiusTwo = sliders[1].value;
    let radiusThree = sliders[2].value;
    let radiusFour = sliders[3].value;

    let blobHeight = inputs[0].value;
    let blobWidth = inputs[1].value;

    let borderRadius = `${radiusOne}% ${100 - radiusOne}% ${100 - radiusThree}% ${radiusThree}% / ${radiusFour}% ${radiusTwo}% ${100 - radiusTwo}% ${100 - radiusFour}%`;

    document.getElementById("blob").style.cssText = `border-radius: ${borderRadius}; height: ${blobHeight}px; width: ${blobWidth}px`;

    outputCode.value = `border-radius: ${borderRadius};`

document.getElementById("copy").addEventListener("click", function(){;
    alert('Code Copied');


Last stage of the project the JavaScript which we added the logic and coded as per the requirement with some conditions. Let us see the Final Output of the project Blob Maker using HTML, CSS & JavaScript.
