+==== Side-by-side code blocks
+
+You can display two code blocks adjacent to each other horizontally. This option is useful when you want to compare code snippets or demonstrate variations of a code example in a parallel view.
+
+To implement side-by-side code blocks, enclose the blocks you want to display with the `[.side-by-side]` attribute followed by `--` delimiters.
+
+For example:
+
+....
+
+[.side-by-side]
+--
