1. What Is a WordPress Theme?
A WordPress theme is a group of files that determine the look and presentation of the content on your website. WordPress themes have been instrumental in driving the success of the platform and allow users to quickly and easily change the way their website looks and works.
What Are WordPress Plugins?
WordPress themes are perfectly complimented by WordPress plugins. WordPress themes are for presentation, and WordPress plugins are for functionality.

2. How to Build Your First Theme
Designing WordPress Themes
Before you can build a WordPress theme, you need to design it (or have a design to work with). In our course Designing for WordPress, you’ll learn the fundamentals of WordPress theme design and all the design considerations you need to think about, from the smallest widget to the largest and most complex page.
Building on a Foundation
If you're building a theme for the first time, you'll want to start with a strong foundation. We've got two courses that cover building a theme using different foundations:
- Bootstrap: Bootstrap is an open-source framework that's designed to give you a head start in developing responsive, mobile first projects on the web.
- Underscores: Underscores is a starter theme by the makers of WordPress themselves. It's designed to give you a “1,000-hour head start” on WordPress theme creation.
3. How to Customize WordPress
Once you've built a basic theme, don't stop there! There are many ways you can customize WordPress and power it up! Learn how to create a more complete package for your clients and theme buyers.
Custom Content Types
The default "Page" and "Post" content types are enough for many websites and blogs, but in order to really harness the power of WordPress as a CMS, you'll want to create custom content types with fields and taxonomies specific to your particular application.
In Using Custom Content Types in WordPress, you'll learn how custom content types work with the WordPress database, plugin, and templating system. Along the way, you'll use custom post types, custom taxonomies, and custom fields to build a simple astronomy CMS for displaying information about the largest moons in the solar system!
Customizing the WordPress Admin
When you deliver a WordPress site to a client, you might want to customize the admin pages as well. You could add custom branding, some help text to further explain how the CMS features work, or an easy-to-edit content sidebar.
Learn how to customize the WordPress admin screens to create a bespoke version of the WordPress admin for yourself and your clients in these courses.
For more on creating custom admin pages for WordPress, read our series of tutorials.

Adding Client Customization
Themes let you customize every aspect of the design and functionality of a WordPress site. But what if you want to let your client customize some aspect of the theme? Perhaps you want to sell a theme on Envato Market, and you want to let buyers adjust the color scheme and logo to match their brand. That's where the WordPress theme Customizer comes in. By making your theme Customizer-ready, you let site owners instantly change their website look and feel from within the WordPress admin UI.
In this course, Envato Tuts+ instructor Rachel McCollin will teach you how to harness the power of the Customizer in your themes. You'll see how easy it is to let users of your theme customize the color scheme of their site and add elements like logos and text.
4. How to Build eCommerce Themes
Adding WooCommerce Support
WooCommerce is the most popular eCommerce platform on the web and the most popular way of bringing eCommerce to WordPress. If you're authoring a theme for ThemeForest, you should consider WooCommerce compatibility as a way to increase sales. And if you're creating an online store, you might be surprised at how easy it is to add WooCommerce support to any third-party theme.
In this Coffee Break Course, you'll learn how to ensure your theme is compatible with WooCommerce. It only takes a few extra lines in a theme's
functions.php file. It's easy to do, and best of all, it even works to add WooCommerce support to a third-party theme.
WooCommerce provides a lot of power and flexibility for simple storefronts out of the box, but to build truly outstanding sites, we have to dig a little deeper. In these courses, Envato Tuts+ instructor Rachel McCollin will teach you how to make use of the WooCommerce API to ensure that the screens on your store fit with your overall theme and your store’s brand. You'll then learn how to enhance your WooCommerce site with features such as embedded video, mega menus, and filter menus.
5. How to Develop Your Own WordPress Plugins
One of the great things about using WordPress is the vibrant plugin ecosystem. There are many thousands of different plugins that promise to improve every aspect of your site. With the right plugins, your WordPress site will run more smoothly, get more visitors, and be less likely to face problems.
In Essential WordPress Plugins, you'll learn how to install and configure free plugins for backup, security, caching, and SEO.
If you can't find the right plugin for the functionality, why not build it yourself? In the course Introduction to WordPress Plugin Development, you'll learn about everything that goes into building a WordPress plugin, and you'll finish up by building your own fully functional plugin using various WordPress APIs.
