Shopify Liquid - Divide product descriptions for more control

divideProdDescriptUp.liquid

{% assign description_parts = product.description | split: '<!--split-->' %}

{%comment%}
  Due to a limitation within Shopify, you have one section to write a general product description. 
  However, if you'd like to split sections and control them via CSS/jQuery/whatever, this provided a way to do that. 
  You may want the client to have access to editing the content, but you need to style the sections. 
  To divide sections, insert <!--split--> when you want a new section. 
  Shown below are snippets to use to output various sections.
	
	Amount of parts: {{ description_parts.size }}
	Index of last part: {% assign index_last = description_parts.size | minus: 1 %}
	First part: {{ description_parts.first }}
	First part: {{ description_parts[0] }}
	Second part: {{ description_parts[1] }}
	Third part: {{ description_parts[2] }}
	Fourth part: {{ description_parts[3] }}
