Bootstrap Pager Component

The Bootstrap Pager component is a simple way to create pagination in your web applications. Pagination is an essential feature in web development that helps to navigate between pages of content, particularly when dealing with large datasets. This article will guide you through the Bootstrap Pager component from its basic structure to more advanced features.

I. Introduction

A. Definition of Bootstrap Pager

The Bootstrap Pager component provides a template for creating a set of links that allow users to navigate between different pages of content. It is part of the Bootstrap framework, which helps developers create responsive and mobile-first websites quickly.

B. Importance of pagination in web development

Pagination plays a crucial role in enhancing user experience by efficiently organizing content. It prevents overwhelming users by breaking down information into manageable chunks, leading to better usability and navigation.

II. Basic Structure

A. Explanation of the HTML structure for the pager

The basic HTML structure for a Bootstrap pager consists of an unordered list (`

`) where each list item (`
• `) represents a page link. The links are created using the anchor (``) tag.

  B. Overview of required classes

  To create a Bootstrap pager, you must include the following classes:

  • pager: This class is applied to the unordered list to style it as a pager.
  • previous and next: These classes are added to list items to create “Previous” and “Next” links.

  III. Example

  A. Simple pager example

  <ul class="pager">
    <li class="previous"><a href="#">← Previous</a></li>
    <li class="next"><a href="#">Next →</a></li>
  </ul>
  

  B. Explanation of the example code

  In the example above, we created a basic pager with two links: “Previous” and “Next.” The `

  ` class is set to pager, with `
  • ` elements for each navigation option. The anchor tags `` within each list item serve as clickable links for the user to navigate to different pages.

      <ul class="pagination">
        <li class="page-item"><a class="page-link" href="#" aria-label="Previous">
          <span aria-hidden="true">←</span>
        </a></li>
        <li class="page-item"><a class="page-link" href="#>1</a></li>
        <li class="page-item"><a class="page-link" href="#>2</a></li>
        <li class="page-item"><a class="page-link" href="#>3</a></li>
        <li class="page-item"><a class="page-link" href="#" aria-label="Next">
          <span aria-hidden="true">→</span>
