Steps to Create a WordPress Theme

Set Up Environment

Install WordPress locally using XAMPP, MAMP, or LocalWP.

Navigate to wp-content/themes/ and create a new theme folder (e.g., my-theme).

Create Essential Theme Files

style.css → Defines theme metadata.

index.php → Main template file.

header.php → Contains the site header.

footer.php → Contains the site footer.

functions.php → Registers theme features.

Define Theme Metadata in style.css

/*

Theme Name: My Custom Theme

Author: Your Name

Description: A simple custom WordPress theme.

Version: 1.0

*/

Build the Theme Structure

Use get_header() and get_footer() in index.php.

<?php get_header(); ?>

<main>

  <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

    <h2><?php the_title(); ?></h2>

    <p><?php the_content(); ?></p>

  <?php endwhile; endif; ?>

</main>

<?php get_footer(); ?>

Register Theme Features in functions.php

<?php

function my_theme_setup() {

  add_theme_support('title-tag');

  add_theme_support('post-thumbnails');

  register_nav_menus(['main-menu' => 'Main Menu']);

}

add_action('after_setup_theme', 'my_theme_setup');

?>
