How are custom HTML elements created in SFCC?

Creating custom HTML elements in Salesforce Commerce Cloud (SFCC) involves using ISML (Interpreted Server-side Markup Language) templates. ISML is a powerful templating language specifically designed for rendering dynamic content in SFCC. When defining custom components, ISML templates allow developers to set the structure and behavior of these components effectively.

Using ISML, developers can intersperse HTML with server-side logic to create robust, reusable components that can be rendered on web pages. This blend of structure and behavior is essential for building rich user interfaces within an SFCC application.

JavaScript libraries facilitate dynamic behavior on the client side but do not define the structure of HTML elements themselves. CSS stylesheets handle the styling aspects, influencing how elements look but not how they are structured. JSON configuration files are often used to manage data and settings rather than creating HTML elements directly. Thus, ISML templates are the appropriate choice for defining custom HTML elements in the context of SFCC.
