Use CSS in Blockly

2. Setup

Download the sample code

You can get the sample code for this code by either downloading the zip here:

Download zip

or by cloning this git repo:

git clone https://github.com/RaspberryPiFoundation/blockly.git

If you downloaded the source as a zip, unpacking it should give you a root folder named blockly-main.

The relevant files are in docs/docs/codelabs/css. There are two versions of the app:

• starter-code/: The starter code that you'll build upon in this codelab.
• complete-code/: The code after completing the codelab, in case you get lost or want to compare to your version.

Each folder contains:

• index.html - A web page containing a simple Blockly workspace.
• toolbox.js - A toolbox with multiple categories.
• index.js - Code to inject a simple workspace.

The complete-code folder also contains the halloween.css file you'll create.

To run the code, simply open starter-code/index.html in a browser. You should see a Blockly workspace with multiple categories.
