[Tex/LaTex] reference amsthm theorem with item list inside

amsthmhyperreflinks

Here is my minimum example. Click from right to left 2-1-1 and notice that it jumps correctly to item 2 then item 1. But then it doesn't jump to remark 1, but instead to the entire first page, as it does when an invalid link is specified. Why is this? It must have to do with amsthm, because when I remove that, it works. But I don't want to remove it since in the real file its predefined styles are used.

\documentclass[a4paper,12pt]{article}
\usepackage{amsthm}
\usepackage[pdfstartview=FitH]{hyperref}
\newtheorem{_Remark}{Remark}
\begin{document}
\begin{_Remark}
\label{rmk:1}
\begin{enumerate}
\item \label{rmk:1a}this is a.
\item \label{rmk:1b}this is b.
\end{enumerate}
\end{_Remark}
\ref{rmk:1}-\ref{rmk:1a}-\ref{rmk:1b}
\end{document}

Apparently I only got the order wrong. Once I include amsthm after hyperref all is fine. I thought I once read somewhere always to include hyperref last. Guess that's just not true any more.

[Tex/LaTex] Hyperref jumps to the wrong equation if the equation has a \tag and cleveref is used

I have a solution. However this might not be the most elegant way.

You have to define your own numbering scheme for hyperref so that each number is unique:

\listfiles
\documentclass{book}

\usepackage{amsmath}
\usepackage{hyperref}
\usepackage{cleveref}

%%% define a new counter and use it for \theHequation which hyperref uses for the links
\newcounter{Hequation}
\renewcommand{\theHequation}{\thechapter.\arabic{Hequation}}
\makeatletter
\g@addto@macro\equation{\stepcounter{Hequation}}
\makeatother

\begin{document}
\begin{equation}\tag{first}\label{eq:first}
   \text{First equation}
\end{equation}

\begin{equation}\tag{second}\label{eq:second}
   \text{Second equation}
\end{equation}

\begin{equation}\label{eq:firstreal}
   \text{First equation without tag}
\end{equation}

\begin{equation}\tag{third}\label{eq:third}
   \text{Third equation}
\end{equation}

\begin{equation}\label{eq:secondreal}
   \text{Second equation without tag}
\end{equation}

\begin{itemize}
   \item A reference to~\eqref{eq:first}.
   \item A reference to~\eqref{eq:second}.
   \item A reference to~\eqref{eq:third}.
   \item A reference to~\eqref{eq:firstreal}.
   \item A reference to~\eqref{eq:secondreal}.
\end{itemize}

As you can see \equation has to be redefined as well. Then equations with and without \tag can be mixed-up without any problems.

[Tex/LaTex] Alternative theorem styles with amsthm package

You can use mdframed:

\documentclass{article}
\usepackage{amsthm}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}

\theoremstyle{plain}
\newmdtheoremenv[
  linecolor=cyan,
  roundcorner=5pt,
  linewidth=1pt
]{theo}{Theorem}

\theoremstyle{definition}
\newmdtheoremenv[
  hidealllines=true,
  leftline=true,
  innerleftmargin=10pt,
  innerrightmargin=10pt,
  innertopmargin=0pt,
]{defi}{Definition}

\begin{document}

\lipsum[4]
\begin{defi}
\lipsum[4]
\end{defi}
\lipsum[4]
\begin{theo}
\lipsum[4]
\end{theo}

\end{document}

The package offers many additional customization options; please refer to the package documentation which also contains numerous examples.

If a same style is to be used for several structures, then it's better to define a style to be used multiple times; the package also offers a very useful \surroundwithmdframed command to apply mdframed settings to an already defined environment. In the following example I define a style, built an structure for definitions using this style, and surround the standard proof environment (from amsthm) with this style:

\documentclass{article}
\usepackage{amsthm}
\usepackage[framemethod=tikz]{mdframed}
\usepackage{lipsum}

\mdfdefinestyle{mystyle}{
  hidealllines=true,
  leftline=true,
  innerleftmargin=10pt,
  innerrightmargin=10pt,
  innertopmargin=0pt,
}
\surroundwithmdframed[style=mystyle]{proof}
\theoremstyle{definition}
\newmdtheoremenv[style=mystyle]{defi}{Definition}

\begin{document}

\lipsum[4]
\begin{defi}
\lipsum[4]
\end{defi}
\lipsum[4]
\begin{proof}
\lipsum*[4]
\end{proof}

\end{document}
