Table of Contents Design Step By Step

Step 1 — Creating a New Project

In this step, we need to create a new project folder and files(index.html, style.css) for creating a simple table of contents. In the next step, you will start creating the structure of the webpage.

Step 2 — Setting Up the basic structure

In this step, we will add the HTML code to create the basic structure of the project.

<!DOCTYPE html>
<html lang="en">
    <meta charset="UTF-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Fixed Table of Contents Design</title>
    <link rel="stylesheet" href="style.css">
    <link rel="preconnect" href="">
    <link rel="preconnect" href="" crossorigin>
    <link href=";400&display=swap" rel="stylesheet">

This is the base structure of most web pages that use HTML.
Add the following code inside the <body> tag:

<div id="fix_toc" class="fix_toc hide">    
        <div class="widget widget_toc">
            <h2 class="widgettitle">Table of Contents <span class="toggle"></span></h2>
                <li class="item-h2"><a href="#1-what-is-bookmarking"> What is Bookmarking?</a></li>
                <li class="item-h2"><a href="#2-what-is-social-bookmarking">What is Social Bookmarking?</a></li>

    <button class="toc_toggle" onclick="toggleToc()"><img src="toc-icon.jpg" alt="toc icon"></button>
        function toggleToc() {
