Build a Basic Block

Build a delimited block

In this section, we’ll create a delimited sidebar block. The delimiter for the sidebar style is four asterisks (****).

  1. Enter the opening delimiter at the beginning of a new line and then press Enter.

    Text in your document.
    
    ****
  2. On the new line, enter your content, such as paragraphs, delimited blocks, directives, and macros. The delimited block’s style will be applied to all of this content until the closing delimiter.

    Text in your document.
    
    ****
    This is content in a sidebar block.
    
    image::name.png[]
    
    This is more content in the sidebar block.
  3. To end the delimited block, press Enter at the end of your last line of content. On the new line, type the closing delimiter.

    Text in your document.
    
    ****
    This is content in a sidebar block.
    
    image::name.png[]
    
    This is more content in the sidebar block.
    ****

That’s it. You’ve built a delimited block.

Build a block from a paragraph

In some cases, you can style a block using the style’s name. If the content is contiguous (not interrupted by blank lines), you can assign the block style’s name in an attribute list placed above the content. This format is often used for single-line listings:

[listing]
sudo dnf install asciidoc

or single-line quotes:

[quote]
Never do today what you can put off `'til tomorrow.
