title: GatsbyJs: Using Markdown and style checkboxes
body: <p>I am using the gatsby-docs-starter and write all my files in markdown.</p>
  
  <p>To style some checkboxes i use</p>
  
  <pre><code>- [x] || [ ] some text
  </code></pre>
  
  <p>Is there a way to style them properly?</p>
  
  <p>I can make them disappear but I cant style them, as I can assign some class to them.</p>
  
  <p>they always render as </p>
  
  <pre><code>&lt;input type="checkbox" checked disabled/&gt;
  </code></pre>
  
  <p>I want to use only Markdown and CSS for this.</p>
  
  <p>thanks</p>
