# Jekyll ## 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://$OGPLUS_KEY.ogplus.net`. ## Find your layout Open `_layouts/default.html` (or whatever layout your pages use). Jekyll uses Liquid templates with YAML frontmatter for page data. This is where you'll add Open Graph meta tags so every page inherits them. ## Add Open Graph meta tags Add the full set of Open Graph tags to your layout's ``. Jekyll's `page` and `site` variables pull in dynamic values automatically: ```html {{ content }} ``` Replace `https://$OGPLUS_KEY.ogplus.net` with the connection URL you copied. ### Tag reference | Tag | Value | Source | |-----|-------|--------| | `og:title` | Page title | `page.title` frontmatter, falls back to `site.title` | | `og:description` | Page description | `page.description` frontmatter, falls back to `site.description` | | `og:url` | Canonical URL | `page.url` resolved to absolute URL | | `og:site_name` | Site name | `site.title` from `_config.yml` | | `og:type` | Content type | `page.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 Jekyll pages and posts set their tags via YAML frontmatter. The layout picks up these values automatically: ```markdown --- title: How to Build a Blog with Jekyll description: A step-by-step guide to building a fast static blog. og_type: article layout: default --- Your post content here. ``` Product page example: ```markdown --- title: Premium Widget description: $49.99 — Our best-selling widget, now available in three colors. og_type: product layout: default --- ``` ## Shared include If you use multiple layouts, extract the meta tags into a shared include: ```html ``` Then include it in any layout: ```html {% include open-graph.html %} ``` ## Configure site variables Set your site-wide defaults in `_config.yml`: ```yaml title: My Blog description: A blog about web development url: https://mysite.com ``` These values are used as fallbacks when pages don't define their own `title` or `description` in frontmatter. ## Verify Deploy 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 Jekyll site. ## Meta tags Add these to your layout's `` alongside your `og:image` tag. They're all optional. ```html ``` 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 /* assets/css/style.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 `
