Equations

Refer to Equations with \eqref{}

% Equation. Entire block numbered.
\begin{equation}
  \begin{aligned}
    E          & = mc^2                              \\
    \implies E & = \sum_{x=2}^{\infty}\frac{y^x}{x!} \\
    F          & = ma                                \\
    F          & = ma                                \\
  \end{aligned}
\end{equation}

% Equation. Selective labeling.
\begin{align}
  E  & = mc^2 \label{eq:einstein} \\
  F  & = ma   \nonumber           \\
  pV & = nRT \label{eq:ideal_gas}
\end{align}

Tables

Refer to tables with \ref{}

% Tables with cell padding (vertical)
% Use \newline to break content in cells
\renewcommand{\arraystretch}{1.5} % default is 1.0
\begin{table}[h!]
  \centering
  \begin{tabular}{|l c |r|}
  % \begin{tabular}{|p{0.3\textwidth}|p{0.3\textwidth}|p{0.3\textwidth}|}

Diameter is \diameter

Colors

% Define a custom color anywhere and use it.
\definecolor{mygreen}{HTML}{3FA722}
\textcolor{mygreen}{Lolzilla!}
% Or use a standard color:
% black, blue, brown, cyan, darkgray, gray, green, lightgray, lime,
% magenta, olive, orange, pink, purple, red, teal, violet, white, yellow
\textcolor{pink}{Pretty pretty pink}

Typefaces

% Use Libertine for both text and equations. Note the packages required above.
\usepackage[T1]{fontenc}
\usepackage{libertinus}
\usepackage{libertinust1math}

% Use the sans-serif variant of a typeface.
\renewcommand{\familydefault}{\sfdefault}

Boxes

% Put a nice box around something
\begin{framed}
\blindtext
\end{framed}

Double Spacing

\usepackage{setspace}

\begin{document}
  \doublespacing
\end{document}

Text Highlighting

\usepackage{color,soul}

\hl{foo}
\hl{\textbf{foo}}
\textcolor{red}{foo}
\textbf{\textcolor{red}{\hl{foo}}}
\textcolor{red}{\textbf{\hl{foo}}}

Multiple Columns

Use multicol for more flexibility. Showing with lipsum text from blindtext. Note that multicol* means that it won't balance content across columns.

\usepackage{blindtext}

\begin{multicols*}{2}
\raggedcolumns
\blindtext\blindtext
\end{multicols*}

If you see the package pushing things around, try this before some block:

\needspace{8\baselineskip}
\begin{framed}
"My mama always said life was like a box of chocolates. You never know what you're gonna get."
\\\\
-- \small{Forrest Gump}
\end{framed}
