#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" i] { .sb-admonition-type * { display: none; } .sb-admonition-type::before { width: var(--admonition-width) !important; } /* 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; } ```
