Themes decide how your WordPress site looks. Being able to make your themes or change existing ones is very important. Start by using starter themes like underscores as a base to build on. Read the WordPress Theme Developer Handbook to learn how to set up your theme correctly.

A good tool for starting plugin development is the WordPress Plugin Boilerplate.

Security Measures

Keeping WordPress sites safe is important and involves checking if your themes and plugins are up to date. Get an SSL certificate to make your site more secure.

This approach lets them build more complex websites using WordPress as the data source.

SEO and Accessibility Compliance

Making sure a site is easy to find and use by everyone is important. Experienced developers optimize websites so they rank well in search engines. In some cases, they even use WordPress features to add descriptions to images and structure to content for better accessibility and SEO.
