HTML content editing

We do not recommend this setting unless you have very specific reasons. It is much harder to use and maintain than markdown but for those who want ultimate control over appearance it is a good option.

Setting HTML

You can specify that an individual page be authored using HTML from the content Settings. You will find the Content type dropdown where you can switch between HTML and markdown.

In order to style your content properly, you should use the Edit HTML header and Edit HTML footer settings. These can be found in the main Settings area on the Global tab.

The header and footer information wrap the HTML content for your page. Below is a typical example of a header.

  <meta charset="UTF-8">
        <link href=".guides/content/css/my-style.css" rel="stylesheet" type="text/css" />    
        <script src="" type="text/javascript"></script>
        <script src=".guides/content/script/my-script.js" type="text/javascript"></script>


And here is the footer.


Support functions

In a page authored using Markdown, you are able to create buttons and other actions. We provide some javascript functions that support the same functionality.

Important : if you use any of the functions listed below then you must load the HTML Header as shown in the example above.
