Extending a theme¶

In this part we will take a look at the power feature of the new theme system. We will create a new theme based on Malibu and in the following chapters we will design the new theme step by step.

Creation of a theme¶

First we create a new theme. To do this, we navigate to the theme folder in our shop and create a new folder called Darkness.

Configuration file¶

Then we change to the created folder and create a new file theme.json. The theme.json is the configuration file of the theme and contains important meta data in JSON format which is read by the shop.

We open the file theme.json and add the following:

{
  "id": "Darkness",
  "title": "Darkness",
  "extends": "Malibu",
  "author": "Gambio",
  "version": "1.0.0",
  "contents": {}
}

• The id identifies our theme. It has to be exactly the same as the folder name.
• The title describes the title of the theme - this can be specified freely. It is often similar to the id and the folder name, but is formatted differently. For example, the folder name and the id could be: GambioChristmasSpecial, and the title could then be called Gambio's Christmas Special Theme.
• The field extends is optional. If our theme extends another theme, we have to enter the id of that theme as the value. For example, if we want to inherit the theme Malibu, we have to enter "extends": "Malibu". If, on the other hand, we want to create a completely new theme, we exclude this field.
• The optional author field describes the author of the theme.
• The version is optional and describes the version of the theme. The format adheres to Semantic Versioning.
• The last field contents is also optional and can contain content manager entries. You will learn more about it in later chapters.
