# Invoice / Receipt Snapshot

Generate a simple, branded invoice or receipt image.

This example shows how to turn a clean HTML layout into a polished invoice. It includes a header with a company name, customer details, a table of items, and a clear total. Great for receipts, confirmations, or sharing invoices as images.

This is a working HTML/CSS to Image API example that produces an image.
The rendered output, source, and non-content request parameters below show the parts needed to reproduce or adapt it.

## Rendered image and interactive editor

## CSS

```css
.wrapper{
  font-family: 'Roboto', sans-serif;
  background: #f7f7f7;
  padding: 20px;
}

.invoice {
  min-width: 500px;
  max-width: 600px;
  margin: auto;
  background: #fff;
  padding: 24px;
  border: 1px solid #ddd;
  box-shadow: 0 2px 6px rgba(0,0,0,0.1);
}

header {
  border-bottom: 2px solid #333;
  margin-bottom: 20px;
}

header h1 {
  margin: 0;
  font-size: 24px;
}

.details {
  margin-bottom: 20px;
}

.items {
  width: 100%;
  border-collapse: collapse;
  margin-bottom: 20px;
}

.items th, .items td {
  border: 1px solid #ddd;
  padding: 8px;
  text-align: left;
}

.items th {
  background: #f0f0f0;
}

.summary {
  text-align: right;
}

.summary p {
  margin: 0.6em 0;
}

.summary .total {
  border-top: 1px solid #ddd;
  padding-top:8px;    
  font-size: 18px;
  font-weight: bold;
  width: fit-content;
  margin-left: auto
}

footer {
  border-top: 1px solid #ddd;
  text-align: center;
  padding-top: 10px;
  color: #555;
  font-size: 14px;
}
```

## Request parameters

These are the additional non-content parameters used by the example. Combine them with the HTML and CSS above when constructing an API request.

```json
{
  "google_fonts": "Roboto",
  "render_when_ready": false,
  "selector": ".wrapper",
  "timezone": "UTC"
}
```

## Complete Ruby request (Net::HTTP)

This is the complete Ruby request for this example using Net::HTTP. It includes the HTML, CSS, authentication setup, API options, and response handling needed to reproduce the output.

```ruby
require "json"
require "net/http"
require "uri"

request = {
    html: <<~'HCTI_HTML',
          <div class='wrapper'>
