HTML5 Table of Contents (TOC)
Table of contents (TOC) is an important navigation tool that can help users easily navigate through lengthy documents or web pages. In HTML5, you can create a table of contents using anchor links and ids. In this article, we will explore how to create a table of contents in HTML5 and how to style it using CSS.
Creating a Table of Contents
To create a table of contents in HTML5, you can use anchor links and ids to link to specific sections of your document. Here is an example of how you can create a simple table of contents for a webpage:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Table of Contents</title>
<style>
/* Add CSS styles to format the table of contents */
ul {
list-style-type: none;
}
li {
margin-left: 10px;
}
</style>
</head>
<body>
Table of Contents
<ul>
<li><a rel="nofollow" href="#section1">Section 1</a></li>
<li><a rel="nofollow" href="#section2">Section 2</a></li>
<li><a rel="nofollow" href="#section3">Section 3</a></li>
</ul>
<h2 id="section1">Section 1</h2>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
<h2 id="section2">Section 2</h2>
<p>Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
<h2 id="section3">Section 3</h2>
<p>Ut enim ad minim veniam, quis nostrud exercitation ullamco.</p>
</body>
</html>
In this example, we have created a simple table of contents with three sections. Each section is linked to its corresponding id using anchor links <a rel="nofollow" href="#section1">Section 1</a>. When a user clicks on a table of contents link, the page will scroll to the specified section.
Styling the Table of Contents
You can style the table of contents using CSS to make it more visually appealing and user-friendly. Here is an example of how you can style the table of contents:
ul {
list-style-type: none;
padding: 0;
}
li {
margin-left: 10px;
}
a {
text-decoration: none;
color: #333;
}
a:hover {
color: #666;
}
In this CSS code, we have removed the default list-style of the unordered list, added some margin to the list items, styled the anchor links to remove the underline, and changed the link color on hover.
Using the TOC in a Gantt Chart
You can also use a table of contents in a Gantt chart to help users navigate through different sections of a project timeline. Here is an example of how you can create a Gantt chart with a table of contents using Mermaid syntax:
gantt
title Project Timeline
section Initiation
Task 1: a1, 2021-10-01, 3d
Task 2: after Task 1, 2d
section Planning
Task 3: a2, 2021-10-06, 3d
Task 4: after Task 3, 2d
section Execution
Task 5: a3, 2021-10-11, 3d
Task 6: after Task 5, 2d
In this Gantt chart example, we have divided the project timeline into three sections: Initiation, Planning, and Execution. Each section contains tasks with start dates and durations. You can create anchor links in the HTML document to link to each section of the Gantt chart using the section titles.
