I want to add this blog template to my Shopify store and How to customize this blog template.
This blog template is great and I choose this to add in my Shopify store.
Template Link - Here
The link you provided just redirects to elfsight website, it does not show the template.
I do kind of understand your requirement. You have a design for a blog page that you need developed. This is doable from the Shopify customiser though to meet some design requirements you might need to make custom sections. This is a tedious and time consuming one certainly more than an average project.
Please reach out via mail for a convenient conversation.
Thanks
