# Liquid

### What is a template language? <a href="#what-is-a-template-language" id="what-is-a-template-language"></a>

Website designers and developers can use a template language to build webpages that combine static content, which is the same on multiple pages, and dynamic content, which changes from one page to the next. A template language makes it possible to re-use the static elements that define the layout of a webpage, while dynamically populating the page with data from the Kajabi Admin. The static elements are written in HTML, and the dynamic elements are written in Liquid. The Liquid elements in a file act as placeholders: when the code in the file is compiled and sent to the browser, the Liquid is replaced by data from the customer account where the theme is installed.

### Liquid syntax <a href="#liquid-syntax" id="liquid-syntax"></a>

Like traditional programming languages, Liquid has a syntax, interacts with variables, and includes constructs such as output and logic. Due to its readable syntax, Liquid constructs are easy to recognize, and can be distinguished from HTML by two sets of delimiters: the double curly brace delimiters `{{ }}`, which denote output, and the curly brace percentage delimiters `{% %}`, which denote logic and control flow.

### Kajabi Cornerstone

### Kajabi Developer Account

The first step to developing Kajabi themes is to establish a Kajabi Developer Account. If you do not already have access to a Kajabi Developer account reach out to <themes@kajabi.com> and ask them to create one for you.
