What you will learn
In this tutorial we will code a very simple 3D table configurator in Blockly editor on bitbybit.dev web cad platform. Then we will export this code and execute it on separate static website on StackBlitz. Matas will set up some basic HTML, CSS and JavaScript for this tutorial without using any 3rd party UI frameworks so that you would see how you can use pure web platform for your sites.
Final result
You can either visit StackBlitz project page or copy these code snippets into your website to make the result from this tutorial appear on your website.
Blockly script
In the following visual script you will find the final code that was exported to JavaScript via "Export to Runner" popover.
Complete Code
You can also download this static index.html file and open it in your browser to see the result. It contains all of the styling, html and script inside it.
