[Tex/LaTex] Left aligned section title

amsarthorizontal alignmentsectioning

I use a LaTeX template which center aligns all section titles. I want to left align these section titles but I do not know how. I tried

\section{\textbf{Introduction and Background}}

but it has no effect on the section title (i.e., it is still centered). I tried

\textbf{Introduction and Background}

and it is left aligned the word "Introduction and Background" but it is no longer a section title and thus the numbering using section number are all messed up.

I am new to LaTeX so please keep it simple.

\section{Introduction and Background}


Note that using formatting macros within section titles as in

\section{\textbf{Introduction and Background}}

is not the recommended way to make general changes. You should rather use


in the definition of \section (and make sure to use a font that provides bold small capitals).
