Simply use the [!vintage] callout type in your notes:

> [!vintage]+ Rotulus
> _ Rotulus *(plural rotuli)* is a long, narrow strip of papyrus or parchment wound vertically around a wooden rod ... _

🗒️ Note: " + or - " After the callout type make the callout collapsible.

Follow these simple steps to use Rotulus in your Obsidian vault:

1. Get the CSS File

Download the rotulus.css file from the repository.

⚠️ Note: To deliver realistic visuals (background of the callouts), this snippet uses embedded Base64 (~2.13 MB). GitHub cannot preview files of this size, so please download the rotulus.css file directly and move it to your .obsidian/snippets/ folder.

If you wish to customize it, open the downloaded file in a local code editor (like VS Code).

Callout Background Customization

A Base64-encoded background image is embedded in the CSS to make the Obsidian callouts look more realistic. You can replace it with your own image using Base64 encoding.

Important Tips:

• Keep Image Size Small: Use small or compressed images for better performance.
• Use VS Code: Edit the CSS file using VS Code (or any proper code editor) instead of basic editors like Notepad++ to avoid lag caused by long Base64 strings.

Note: If you don't want to deal with editing, you can simply use the file as-is without changing anything!

⚠️ Note: If you have a large monitor/screen then your background may crash like that.

Solve :

• Open the downloaded file in a local code editor (like VS Code).

• Go to 116th line, then just increase the width.
