For the most Required Files, a WordPress theme depends on

  1. index.php – the main template file
  2. style.css – the main style file

Index.php is the theme’s main template file that determines how different elements will be arranged on the page and then styles.css file is used to format them. If the theme has no additional templates – WordPress displays all pages as per the index.php file.

You may find some additional files in a theme’s folder including ( more depends on on-site design):

  • Classic themes are built with PHP files – including template files
  • Block themes are built with blocks and HTML files
  • Localization files
  • CSS files
  • JavaScript
  • Graphics
  • Text files – usually license info, readme.txt instructions, and a changelog file

All the above files dictate and contribute to creating the website’s overall design.

Next, we are going to see WordPress theme development with Bootstrap.

WordPress Theme Development With Bootstrap

Bootstrap is an open-source framework, that can be used to create responsive WordPress themes through its CSS and JavaScript-based design templates.

8 Simple Steps to Develop WordPress Theme With Bootstrap

Here are the steps for creating a WordPress theme development bootstrap 

Step 1: Unzip Bootstrap

  1. First, install WordPress on your domain.
  2. Download and unzip Bootstrap.
  3. Then, connect it Using an FTP client like FileZilla.
  4. Navigate it to wp-content > themes.
  5. Create a new folder under the Themes folder by the name “BootSTheme”. Upload all the contents of unzipped Bootstrap to this folder.
  6. Generally WordPress installation contains the following files:
    • footer.php
    • header.php
    • index.php
    • style.css

So, make four empty files for all file types in the BootSTheme folder.

Unzip Bootstrap

Step 2: Configure Bootstrap

To configure bootstrap, go to BootSTheme folder, open the style.css and paste the following code.

  1. /*
  2. Theme Name: MyTheme
  3. Theme URI:
  4. Description: Mytheme Built on bootstrap
  5. Version:1.1
  6. Author: Ahsan Parwez
  7. Author URI:
  8. */

These are comments are used to provide descriptions and details about the theme. Here you change these comments to reflect a more accurate message in your theme.

Step 3: Copying the Code

To start the dev process, you have to copy the code in the bootstrap.min.css file and paste into the style.css file. At this point, the style.css file should look like as shown below

Copying the Code

Step 4: Set up HTML Template

Here you can use HTML themes. WordPress has built-in functions such as get_header() and get_footer() that by default call the files header.php and footer.php respectively. You can start by cutting the HTML code from the top to the first container div and pasting it into the header.php file. The file should look like this:

Set up HTML Template

The footer.php file will contain the rest of the code:


To load the header and the footer, use the WordPress built-in function to call these elements. For the same, paste the following code in the index.php:

  1. <?php get_header(); ?>
  2. <?php get_footer(); ?>

Now header and footer elements will load on our website, but we will get a basic page without any style format (as shown below).


Step 5: Setting the Header and the Footer

In the header.php file, now import the Bootstrap stylesheet by using the WordPress function echo get_stylesheet_uri() (read more the function in the WordPress Codex). This will help you import the style.css onto the website and you will be able to see a top menu bar now.

Now for setting style in the header, you can add the style.css by adding the following code at the top of the header.php file. But until JavaScript features on your page do not work, we will not see any drop-down menus. 

  1. <link rel="stylesheet" type="text/css" href="<?php echo get_stylesheet_directory_uri(). '/style.css' ?>">


To enable this, we you have to import js files by directly importing the file by URL in the footer.php. Paste its code before the closing body tag.

  1. <script src="../wp-content/themes/MyBSTheme/js/bootstrap.min.js"></script>

WordPress is known for its customization and plugins. Now, place the plugins hooks,and paste <?php wp_head(); ?> and <?php wp_footer(); ?> in header.php and footer.php files. Also, to set dynamic titles of the website, we are going to use wp_title(); function in the header.php file between the <title> tags.

  1. <title><?php wp_title(' | ',true,'right'); ></title>

The above code will call the title of the post separated by ‘|’ than the site name. Here‘right’ defines the location of the post title to be right of the separator.

Step 6: Displaying the Featured Posts

Next, you have to call posts dynamically into the homepage (as displayed by the ) and display them at the top, similar to the featured posts that you see on many WordPress sites.

Write the following code into your index.php:

code into index.php

As in the above code, used while loop and set the number of posts to one by using post_per_page. This line will only display the latest blog post at the top of the page, and after the loop closes, the query_posts resets.

The class jumbotron is defined in the bootstrap.min.css file. You can use it to style the featured posts by using <h2> tags and the_permalink(); function. The hyperlink is created on the post title, and the_permalink(); is used to links to the URL of the entire post. To show an excerpt of the post, you can use another built-in WordPress function, the_excerpt();.


Step 7: Listing Your Categories

You can list the categories on the left of the homepage and create several instances of a div styled with the Bootstrap classes and the WordPress function wp_list_categories();.

Paste the given code in the index.php file:

  1. <div class="panel panel-default panel-body">
  2. <div>
  3. <div>
  4. <ul>
  5. <?php wp_list_categories('orderby=name&title_li='); ?>
  6. </ul>
  7. </div>
  8. </div>
  9. </div>

Here you can list the categories by name with a nice hover effect.

Step 8: Display the Latest Posts and Authors

Finally, you can show show the latest blog posts on the homepage. You have to start another div tag and under this div, and use similar while loop technique that you used in the featured post, but we are not going to limit it with query_posts();.

  1. <div>
  2. <?php while(have_posts()) : the_post(); ?>
  3. <h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>
  4. <p><?php the_excerpt(); ?></p>
  5. <p> posted by <?php the_author(); ?>
  6. <?php endwhile; wp_reset_query(); ?>
  7. </div>

WordPress functions the_author(); is used to fetch the username of the author of the post. you can use it to dynamically display the name of the post author.


So, hope these steps on WordPress theme development bootstrap help you with the WordPress Theme Development process effectively.
