A callout for a folder structure

Share & showcase

Hi!

Just sharing some CSS I wrote to create a callout suited to represent file/folder structures. For example:

This has been obtained with the following Markdown, where the folder structure is just implemented through a list within a folder callout:

> [!folder] folder
> - 📁 Folder *`           `← root folder*
> 	- 📄 Item 1 *`         `← some item in the folder*
> 	- 📁 Subfolder 1 *`    `← another folder*
> 		- 📄 Subitem 1-1
> 		- 📄 Subitem 1-2
> 	- 📁 Subfolder 2
> 		- 📄 Subitem 2-1
> 		- 📄 Subitem 2-2
> 		- 📁 Subsubfolder
> 			- 📄 ==Name==.jpg *`   `… Some variable name?*
> 			- …

In the above example, you’ll find that emphasis (*…*) is used to add comments/explanations, inline code (`…`) is used within said comments for space control, and highlights (==…==) is used for variable names.

Here’s the CSS:

.callout[data-callout=folder i] {
  --list-indent: 0em;
  --indentation-guide-color: transparent;
  overflow: scroll;
}
.callout[data-callout=folder i] .list-bullet {
  display: none;
}
.callout[data-callout=folder i] ul {
  -webkit-margin-after: 0;
          margin-block-end: 0;
}
.callout[data-callout=folder i] li {
  --list-indent: 1.5em;
  list-style-type: none;
  font-family: var(--font-monospace);
  white-space: nowrap;
}
.callout[data-callout=folder i] li li {
  position: relative;
  box-sizing: border-box;
}
.callout[data-callout=folder i] li li::before,
.callout[data-callout=folder i] li li::after {
  content: "";
  position: absolute;
  left: -1em;
  background: var(--list-marker-color);
}
.callout[data-callout=folder i] li li::before {
  top: 0.85em;
  width: 10px;
  height: 1.5px;
  margin: auto;
}
.callout[data-callout=folder i] li li::after {
  top: 0;
  bottom: 0;
  width: 1.5px;
  height: 100%;
}
.callout[data-callout=folder i] li li:last-child::after {
  height: 0.85em;
}
.callout[data-callout=folder i] li .list-collapse-indicator {
  position: absolute;
  left: -2em;
  margin: 0;
}
.callout[data-callout=folder i] li em {
  opacity: 0.5;
  font-family: var(--font-text);
}
.callout[data-callout=folder i] li code {
  font-size: 1em;
  font-family: var(--font-monospace);
  font-style: normal !important;
  background: none;
  white-space: pre;
  margin: 0;
  padding: 0;
}
.callout[data-callout=folder i] li mark {
  font-style: italic;
  color: #d3a3e5;
}
.callout[data-callout=folder i] .callout-content {
  overflow-x: visible;
}
