This post shows how to add custom styles for blockquotes. Based on jekyll-gitbook implementation.

We decided to support the same custom blockquotes as in jekyll-gitbook, which are also found in a lot of other sites’ styles. The styles definitions can be found on the _base.scss file, more specifically:

/* Tips, warnings, and dangers */
.post .post-content blockquote {
  &.block-tip {
    border-color: var(--global-tip-block);
    background-color: var(--global-tip-block-bg);

    p {
      color: var(--global-tip-block-text);
    }

    h1,
    h2,
    h3,
    h4,
    h5,
    h6 {
      color: var(--global-tip-block-title);
    }
  }

  &.block-warning {
    border-color: var(--global-warning-block);
    background-color: var(--global-warning-block-bg);

    p {
      color: var(--global-warning-block-text);
    }

    h1,
    h2,
    h3,
    h4,
    h5,
    h6 {
      color: var(--global-warning-block-title);
    }
  }

  &.block-danger {
    border-color: var(--global-danger-block);
    background-color: var(--global-danger-block-bg);

    p {
      color: var(--global-danger-block-text);
    }

    h1,
    h2,
    h3,
    h4,
    h5,
    h6 {
      color: var(--global-danger-block-title);
    }
  }
}

A regular blockquote can be used as following:

> This is a regular blockquote
> and it can be used as usual

This is a regular blockquote and it can be used as usual

These custom styles can be used by adding the specific class to the blockquote, as follows:

> ##### TIP
>
> A tip can be used when you want to give advice
> related to a certain content.
> {: .block-tip }
TIP

A tip can be used when you want to give advice related to a certain content.

> ##### WARNING
>
> This is a warning, and thus should
> be used when you want to warn the user
> {: .block-warning }
WARNING

This is a warning, and thus should be used when you want to warn the user

> ##### DANGER
>
> This is a danger zone, and thus should
> be used carefully
> {: .block-danger }
DANGER

This is a danger zone, and thus should be used carefully
