For questions regarding the {adjustwidth} environment from the {changepage} package.

The adjustwidth environment from the changepage package can be used to locally change the left and right margins of a document. The environment takes two mandatory arguments that can be either positive (increase respective margin) or negative (decrease respective margin).

\begin{adjustwidth}{<change to left margin>}{<change to right margin>}

The starred variant adjustwidth* is useful for twosided documents and alternates the values of the margins between odd and even pages.

\begin{adjustwidth*}{<change to inner margin>}{<change to outer margin>}

The adjustwidth environment can also be used inside of a floating environment such as figure or table.
