#level/intermediate Silverbullet supports [admonitions](https://github.com/community/community/discussions/16925) using GitHub syntax (`note` and `warning`). > **note** This is a > note admonition > **warning** This is a > warning admonition Custom admonitions can be added in a [[Space Style]] using the following format: ```space-style // Replace the keyword with a word or phrase of your choice .sb-admonition[admonition="keyword"] { .sb-admonition-type * { display: none; } // The icon can be a link or an embedded image like shown here --admonition-icon: url('data:image/svg+xml,'); // The accent color --admonition-color: green; } ```
