Underscores WordPress Theme: A Perfect Starting Point for Custom WordPress Theme Development

If you’re a WordPress developer looking to create a custom theme from scratch, you might be wondering where to begin. The sheer number of files and complex structure involved in theme development can be daunting. But there’s an excellent solution that will set you on the right path: the Underscores (_s) WordPress theme.

Underscores is a lightweight, bare-bones starter theme that comes with the bare essentials of a WordPress theme, and it’s perfect for developers who want to create a unique, custom theme without reinventing the wheel. In this article, we’ll explore what Underscores is, how it can be used as a basic template, and how to customize it to build your own fully functional WordPress theme.

What is Underscores (_s)?

Underscores, often referred to as “_s” (pronounced “underscores”), is an open-source WordPress starter theme developed by Automattic, the company behind WordPress.com. It provides a simple and well-structured foundation for building custom WordPress themes. It doesn’t come with extra functionality like many premium themes but offers a clean slate that developers can extend and modify to fit the needs of their projects.

The key purpose of Underscores is to give developers a lightweight starting point with modern HTML5, CSS3, and WordPress coding standards built in. It has minimal design and structure, which means it’s easy to adjust and adapt without having to work around excessive code or pre-built features.

How to Use Underscores as a Template for Your Custom WordPress Theme

Underscores is a starter theme and not a fully functional theme in itself. However, it contains all the core components needed to create a WordPress theme. Here’s how you can get started:

Step 1: Download and Set Up Underscores

The first step is to visit the Underscores website at underscores.me. From there, you can generate your own version of the theme. All you need to do is enter the name of your theme (e.g., “MyCustomTheme”) and click the “Generate” button. This will create a downloadable .zip file of Underscores with the name you’ve provided.

Once downloaded, unzip the file and upload it to the wp-content/themes/ directory of your WordPress site. You can do this via FTP or through your hosting control panel’s file manager.

Step 2: Activate Your Underscores Theme

Once the theme is uploaded, go to the WordPress Dashboard, navigate to Appearance > Themes, and you should see your newly uploaded Underscores theme listed. Activate it, and you’ll be able to see it in action.

At this stage, the theme will still look very basic with just the default WordPress layout. That’s exactly what you want. From here, you’ll begin customizing and adding functionality.

Step 3: Customize the Theme Structure

The beauty of Underscores lies in its simplicity. The structure is already organized, and it follows the best practices of WordPress theme development. The main files you’ll be working with are:

  • style.css – The main stylesheet for the theme.
  • index.php – The default template file that serves as the base for all pages.
  • header.php – The header of your site, including site navigation and metadata.
  • footer.php – The footer section of your site.
  • functions.php – A critical file that allows you to add theme functionality like custom post types, theme options, or enqueue styles and scripts.
  • sidebar.php – The sidebar template (if you choose to use one).
  • single.php – Template for individual blog posts.
  • page.php – Template for static pages.

These files are essential, and you can add or remove files as necessary depending on your theme’s requirements.

Step 4: Add Your Custom Styles

Underscores comes with basic CSS for structure, but you’ll want to replace or extend it to match your design preferences. You can modify style.css directly, or create separate CSS files for specific parts of your site (e.g., for custom components or layouts).

Use your own branding, fonts, colors, and layout ideas to transform the theme’s base into something uniquely yours. You can use CSS frameworks like Bootstrap or Tailwind CSS, or write your own custom CSS if needed.

Step 5: Add Custom Features and Templates

Now comes the fun part: adding custom functionality! Here are a few things you might want to add to your custom theme:

  • Navigation Menus: Underscores provides a basic navigation menu setup in header.php. You can extend it to create more complex menu structures using WordPress’s built-in wp_nav_menu() function.
  • Custom Post Types: You can register custom post types (e.g., portfolios, testimonials) by adding code to functions.php. This will help you create content types beyond regular posts and pages.
  • Widgets: If you plan to have dynamic sidebars or footer widgets, you can register widget areas in functions.php and use them in sidebar.php or footer.php.
  • Responsive Design: Underscores is built with mobile responsiveness in mind, but you may need to adjust breakpoints, grid layouts, or other CSS rules to match your design.

Step 6: Test and Optimize

Once you’ve added all the custom features and design elements, it’s time to test your theme. Make sure it works correctly across different devices and browsers. Pay attention to performance, as a custom theme should load quickly. You can use tools like Google PageSpeed Insights to identify areas for improvement.

Additionally, check for any issues with theme compatibility with popular plugins, SEO optimization, and accessibility. WordPress has certain standards and best practices to follow, so be sure to comply with them.

Why Use Underscores?

Underscores offers several advantages as a starter theme:

  1. Simplicity and Flexibility: It provides only the essential files and a basic structure, which allows you to add your own custom features and styles without dealing with unnecessary bloat or extra features.
  2. Best Practices: Underscores is built following WordPress’s coding standards and best practices. This makes it easy to integrate into your existing projects and ensures it’s up to date with the latest WordPress developments.
  3. Open Source: Underscores is free to use and modify, making it accessible to developers of all levels.
  4. Developer-Focused: Since it doesn’t come with built-in design elements, it’s perfect for developers who want to create highly custom, unique themes.

Underscores is the ideal starting point for WordPress developers who want to build custom themes. It provides a clean, minimalist foundation that allows you to focus on designing your theme and adding functionality without getting bogged down by unnecessary features or bloat.
