Textual offers a few different *units* which allow you to specify dimensions relative to the screen or container. Relative units can better make use of available space if the user resizes the terminal.
- Percentage units are given as a string containing a number followed by a percentage symbol, e.g. `"50%"`. Setting a dimension to a percentage unit will size that dimension to that percentage of the *parent's* size in that dimension. For instance, setting width to `"50%"` will cause the width of the widget to be half the width of its parent.
- Percentage units are given as a number followed by a percent (`%`) symbol and will set a dimension to a proportion of the widget's *parent* size. For instance, setting width to `"50%"` will cause a widget to be half the width of its parent.
- View units are similar to percentage units, but explicitly reference a dimension. The `vw` unit sets a dimension to a percentage of the terminal *width*, and `vh` sets a dimension to a percentage of the terminal *height*.
- The `w` unit sets a dimension to a percentage of the available width (which may be smaller than the terminal size if the widget is within another widget).
- The `h` unit sets a dimension to a percentage of the available height.
