## Syntax

### base

Argument specification: `m:L m:L m:L`

Used to insert an explicit blank box/space with specified width, height, and depth in math mode.

### textmacros

Argument specification: `m:L m:L m:L`

Used to reserve blank space with explicit width, height, and depth in text fragments or legacy MathJax TeX input.

## Examples

```latex
\Space{1em} 2pt {3pt}
```
