\parbox ¶Synopses, one of:
\parbox{width}{contents}
\parbox[position]{width}{contents}
\parbox[position][height]{width}{contents}
\parbox[position][height][inner-pos]{width}{contents}
Produce a box of text that is width wide. Use this command to make
a box of small pieces of text, of a single paragraph. This command is
fragile (see \protect).

The contents are processed in a text mode (see Modes) so
LaTeX will break lines to make a paragraph. But it won’t make
multiple paragraphs; for that, use a minipage environment
(see minipage).
The options for \parbox (except for contents) are the same
as those for minipage. For convenience a summary of the options
is here but see minipage for a complete description.
There are two required arguments. The width is a rigid length (see Lengths). It sets the width of the box into which LaTeX typesets contents. The contents is the text that is placed in that box. It should not have any paragraph-making components.
There are three optional arguments, position, height, and
inner-pos. The position gives the vertical alignment of the
parbox with respect to the surrounding material. The supported
values are c or m to make the vertical center of the
parbox lines up with the center of the adjacent text line (this is the
default), or t to match the top line of the parbox with
the baseline of the surrounding material, or b to match the
bottom line.
The optional argument height overrides the natural height of the box.
The optional argument inner-pos controls the placement of
content inside the parbox. Its default is the value of
position. Its possible values are: t to put the
content at the top of the box, c to put it in the vertical
center, b to put it at the bottom of the box, and s to
stretch it out vertically (for this, the text must contain vertically
stretchable space).
