# Middleman ## Getting Started ## Create a connection 1. Sign in to [OpenGraph+](/) 2. Go to your website's **Meta Tags** page 3. Create a new connection and copy your connection URL Your connection URL looks like `https://$OGPLUS_KEY.ogplus.net`. ## Find your layout Open `source/layouts/layout.erb`. Middleman uses ERB templates and YAML frontmatter for page data. This is where you'll add Open Graph meta tags so every page inherits them. ## Add Open Graph meta tags Add the full set of Open Graph tags to your layout's ``. Use `current_page.data` to pull in dynamic values from each page's frontmatter: ```erb "> "> "> <%= yield %> ``` Replace `https://$OGPLUS_KEY.ogplus.net` with the connection URL you copied. ### Tag reference | Tag | Value | Source | |-----|-------|--------| | `og:title` | Page title | `current_page.data.title` frontmatter | | `og:description` | Page description | `current_page.data.description` frontmatter | | `og:url` | Canonical URL | Site URL + `current_page.url` | | `og:site_name` | Site name | Hardcoded in layout | | `og:type` | Content type | `current_page.data.og_type` frontmatter, defaults to `website` | | `og:image` | Social card image | OpenGraph+ connection URL + page path | | `twitter:card` | Card format | `summary_large_image` for large previews | ## Dynamic tags from frontmatter Middleman pages set their tags via YAML frontmatter. The layout picks up these values automatically: ```markdown --- title: About Our Company description: We build tools for developers. --- ``` Blog post example: ```markdown --- title: Shipping Our New Feature description: A deep dive into how we built real-time previews. og_type: article --- ``` ## Verify Build your site and open the preview tool in your OpenGraph+ dashboard. Paste a URL from your site to confirm the meta tags and social card image render correctly. ## Customize OpenGraph+ captures your page in a headless browser and renders it as an image. You control what gets captured using meta tags in your layout and CSS in your stylesheets. All of the rendering options below are standard HTML meta tags and CSS, so they work the same regardless of framework. The [HTML, CSS, & HTTP guide](/docs/html-css) covers each one in detail. This page shows how to wire them into a Middleman site. ## Meta tags Add these to your layout's `` alongside your `og:image` tag. They're all optional. ```erb <%# Render at 800px wide instead of the default %> <%# Only capture this element instead of the full page %> <%# Inject inline styles on the captured element %> ``` See the [Rendering](/docs/html-css/rendering) guide for what each meta tag does and how they interact. ## CSS styling OpenGraph+ adds a `data-ogplus` attribute to your `` element during capture. Use it in your stylesheets to hide navigation, adjust spacing, or restyle anything for the social card without affecting your actual site. ```css /* source/stylesheets/site.css */ html[data-ogplus] { nav { display: none; } footer { display: none; } .hero { padding: 60px; } } ``` If you're using Tailwind, there's a plugin that gives you `ogplus:` variants like `ogplus:hidden` and `ogplus-twitter:bg-sky-500`. See [CSS Styling](/docs/html-css/data-attributes) for plain CSS examples and [Tailwind setup](/docs/html-css/data-attributes#tailwind-css). ## Templates For fully custom social card layouts that pull content from your page, use `
