Enumitem

• Why Does `\begin{enumerate}[(a)]` Not Indent Items?
  The optional [(a)] syntax changes enumerate labels, not list indentation. Use enumitem's label and leftmargin options to control both.
• How to Make “Properties” Bold in a LaTeX List
  Use \textbf{Properties} for a heading, or set enumitem’s label option to bold property names or numbers in an enumerate list.
• Can You Use align* Inside enumerate* in LaTeX?
  The reason align* fails inside enumitem’s enumerate* is that one is display math and the other an inline list. Use regular enumerate for equations.
