Timber themes

Create WordPress themes with OOP code and the Twig template engine

Timber helps you create fully-customized WordPress themes faster with more sustainable code. With Timber, you write your HTML using the Twig Template Engine separate from your PHP files. This cleans up your theme code so, for example, your PHP file can focus on being the data/logic, while your Twig file can focus 100% on the HTML and display. Once Timber is installed and activated in your plugins directory, it gives any WordPress theme the ability to take advantage of the power of Twig and other Timber features. The GitHub version of Timber requires Composer and is setup for inclusion within a theme or plugin. If you'd prefer one-click installation for your site, you should use the WordPress.org version. Timber is great for any WordPress developer who cares about writing good, maintainable code. It helps teams of designers and developers working together.
