How can I customize the layout of my blog with coding?

Topic summary

Goal: Customize a Shopify blog (Pipeline theme 6.3.0) to achieve a more professional layout.

Requested changes:

  • Add a dynamic table of contents generated from H2/H3 headings.
  • Move “Recent articles” to the bottom; replace its current spot with a newsletter sign‑up form.
  • Add social sharing buttons at the top of the post or as a side widget.
  • Redesign the featured image/header area to cleanly integrate with the H1 title.

Context:

Response/update:

  • One respondent states the changes are feasible and not too time‑consuming overall but require coding and testing; invites discussion via DM.

Status:

  • No code or step‑by‑step solution posted. No decisions made. Thread remains open/pending further assistance.

Can someone please tell me the code I’d need to customize the theme of my blog. I don’t like how unprofessional it looks. I added to images, one of my actual blog and another of they layout I would like to implement. I squared in red boxes what I would want to add - a dynamic table of contents that pulls from the h2 and h3 headers of each blog post. I want to move my recent articles that display to the bottom of the blog and replace that position with a newsletter sign up form as shown in the red rectangle. I want to add social sharing buttons to the top of the blog post or as a side widget. I want to change the featured photo header and make it cleaner with my h1, as shown in the example.

I tried to customize the theme myself, using Javascript, html, and css (I have a very basic understanding of code) but couldn’t figure this out. Can someone help me out? I need this done as soon as possible. I have the 6.3.0 Pipeline theme. I contacted Pipeline and they said I need a Shopify expert. Because I have a basic understanding of code, I also know implementing these features should not take too long.

Before I share my URL link, DO NOT contact me through my business contact form. I delete all messages I receive offering services through my business form. Please only respond here.

Thanks!

Hello there, this can be done, it shouldn’t take too long but would take a bit of time to code this and test to make sure everything well though. We can discuss specifics in my DM.
