   * In general, the *visible* width of an input element is defined by the Bootstrap column width (and *not* the width given
     here). The width value here only has an impact on calculating the final height in the `auto height` mode.
   * The dynamic Bootstrap width of the shown textarea element makes it hard to calculate the real needed height. The
     implementation is only a 'best guess'.
-  * `<width>,<min height>`: with a `<min height>` > 1 the input element is of type 'textarea'.

     If a line is longer than `<width>`, the height of the line counts as `length(<line>) / <width> + 1` lines. The height
     is never less than `<min height>` or greater than `<max height>`.
