As an introduction to the course, get to know Ignacio, who tells you about his career and some of his work in WordPress. He also shares a few of his influences within the world of web design.

Before getting to work, install a code editor on your computer as well as some other resources that Ignacio provides. Take a brief look at the WordPress database where all the information you write for your web is stored, and install a series of plug-ins to help you debug your code.

Next, learn to identify the key design units of a basic theme and write the code to develop them before focusing on their structure. Begin by developing the homepage's header and footer, essential parts of any website, and apply several functions to add scripts and styles.

Familiarize yourself with what hooks are⁠—the foundations of WordPress⁠—and how they work. Most importantly, you can use them to extend any part of WordPress without touching the base code, as well as specify what features your theme will support.

Move on to one of WordPress' most powerful tools: the Loop. Any page, post, or search result is displayed through this function. Discover how images behave within WordPress and the resizing operations that apply to each image. Next, learn how to separate the content of your theme into several templates depending on their type.

Ignacio continues by explaining what makes WordPress such a flexible platform, due in large part to its compatibility with a host of extensions. Start with CSS body and content⁠—very important when it comes to styling your website.

Learn what they are and how you can display custom posts, taxonomies, meta boxes, post templates, and custom pages in your theme. Then see how to configure the look of your live webpage by applying a range of settings to the header and footer, as well as the logo. Although this is not a JavaScript course, Ignacio teaches you how to add a touch of interactivity to your page using this programming language.

Finish up by learning what child themes are and putting the finishing touches on your WordPress theme before packaging it for use at a later date.

What is this course's project?

Create a website with two different types of content: a blog and a portfolio.
