For each block, set your own content and style choices. Advanced users can customize a block even further using the built-in code editor to inspect and modify its underlying HTML and CSS code.
Snowball is developed and maintained by the openHTML research team at Drexel University, with the goal of broadening participation and empowering people to be more expressive on the web.

- How can I add custom styles to a block?
To apply your own customizations to a block, click the „</>” code button. This will open the block with the code view. In the CSS panel in the bottom right, scroll down and add your own CSS. This CSS will only be applied to this block, not any other blocks in the article.
- How can I customize all of the blocks in an article at once?
Click the „gear” settings button in the top right of the article. A „Custom HTML head code” field is available where you can add CSS that’s applied to the whole article. Be sure to wrap your CSS in style tags. You can also use this field to add web fonts and scripts to the article.
- How can I use Snowball’s minimal theme?
By default, Snowball articles use the active theme of your WordPress site. However, Snowball works best with the minimal, one-column theme that’s included in the plugin. To activate it, click the „gear” settings button in the top right of the article, check the „Use Snowball theme” option, and save the article.
- How do I customize the permalink slug for Snowball articles to something other than /snowball/?
Use a plugin like Simple Post Types Permalinks to modify the default slug.
- How do I add items to a Table of Contents block?
The Table of Contents block is based on all of the HTML IDs used in an article. You can add an ID to an HTML element within a Text or HTML block, as well as text fields like an Image block’s caption, in order to have them listed in a table of contents.
- Can I use my own template for Snowball articles?
Yes, administrators can create a custom template where they can add their own headers, footers, stylesheets, and scripts. For information on how the template should be formatted and where it should be placed, read the doc Using a Custom Template.
