# Template Editor: Start with Coupon Code Badge Instagram Post (Square) Template

Customize the Coupon Code Badge Instagram Post (Square) Template in the HTML/CSS to Image template editor, then save it for API image generation.

The HTML/CSS to Image API (HCTI) creates images, PDFs, and website screenshots from HTML/CSS, live URLs, or reusable templates. It also supports visual template editing, automated Open Graph images, signed image URLs, batch rendering, direct-to-storage output, and an OAuth-connected MCP server for AI agents.

The template playground is the browser-based visual editor for reusable image templates: configure the canvas, compose blocks, add variables, preview placeholder values, and save the result for rendering through the API.

## What you can do

- Build layouts from text, images, shapes, panels, and other reusable blocks.
- Define variables for content and styling that changes between renders.
- Preview the template with realistic values before saving it.
- Render saved templates through the HTML/CSS to Image API.
