This or That — Free Instagram Vote Post Template With Diagonal Split

This or That is a free social media template that turns a simple choice into a loud, colourful post. The canvas is cut on a diagonal: indigo above, rose below, with a yellow "OR" badge sitting right on the dividing line. Each side holds one big option with a white A or B circle, and the footer tells people how to vote.
Designed to be answered in one word
The best this-or-that posts have options that can be typed in a second: "Dark mode" or "Light mode", "Tabs" or "Spaces", "Coffee" or "Tea". The template makes each option huge, with a short question chip at the top, so there is no doubt what is being asked. The prompt line at the bottom, "Comment A or B", gives people the exact reply to type, which is why this format reliably fills a comment section.
Fits a feed, not just a Story
Instagram's poll sticker lives in Stories. This template is for the feed, where votes happen in the comments, so the result stays visible and you can reply to people and keep the thread going. Use it for audience polls, fun team debates, or a quick way to ask followers which product colour, logo or feature to ship.
Colours and sizes
The two sides take their own colours, so swap them to your brand pair or to the two sides of the debate, such as red against blue. The diagonal split runs across the portrait, square and Story sizes, and the layout switches to a left-and-right split on the 16:9 and LinkedIn sizes. Long options shrink to fit, and you can export PNG, JPEG, PDF, an animated video where the options appear one after another, or the HTML.
For a Story that uses Instagram's own sticker, use Story Poll. To ask for an opinion rather than a choice, try Hot Take.
Extend with AI
Take This Post Further With AI
Ask an AI assistant to adapt the This or That HTML and CSS: write ten this-or-that pairs for your niche, build an interactive version that counts clicks on each side, or generate a series with a new pair each day of the week.
Prompt to recreate it
Copy this into your AI assistant of choice to build the effect from scratch, or as a jumping-off point for your own variant:
Create a 1080×1350 "this or that" social post in plain HTML and CSS.
- The whole canvas is rose (#e11d48). Over it, an indigo (#4f46e5) layer clipped with clip-path polygon(0 0,100% 0,100% 40%,0 60%) to make a diagonal split.
- A small uppercase pill at the top with a translucent dark background: "Your coding setup?".
- In the indigo half: a white circle with the letter A and the huge white word "Dark mode". In the rose half: a white circle with B and "Light mode".
- A round yellow badge reading "OR", tilted slightly, centred on the diagonal with a soft shadow.
- A footer with a "Comment A or B" pill on the left and the handle on the right.
- Size everything with a CSS variable --u equal to 1% of the shorter side.Want to tighten it up first? Run this prompt through the AI Prompt Studio to score it across 8 quality dimensions, catch anti-patterns, and tune the wording for Claude, ChatGPT, or Gemini before you paste it in.
