如何将副标题的第二行与第一行对齐？

Question

我使用子标题来描述彼此相邻的多个图表。对于较长的子标题，我遇到的问题是文本没有很好地对齐，第二行滑到了 (a) 和 (b) 标签下方。有没有办法将第二行的开头与行号 1 中的子标题文本的开头对齐？

非常感谢你的帮助！

附件是一个例子：

\documentclass[authoryear, review]{elsarticle} 

\usepackage{graphicx}
\usepackage[font = footnotesize, labelfont=bf]{subcaption}
\usepackage[font = footnotesize, labelfont=bf]{caption}
\begin{document}

\begin{figure}
    \centering
    \begin{subfigure}[b]{0.45\textwidth}
        \includegraphics[width=\textwidth]{Sails}
        \caption{This is a rather long sub-caption for this nice picture of sails}
    \end{subfigure}
    ~ 
    \begin{subfigure}[b]{0.44\textwidth}
        \includegraphics[width=\textwidth]{Sails}
        \caption{This is a rather long sub-caption for this nice picture of sails}
    \end{subfigure}
    \caption{\textbf{This is the overall caption for this group of sailing pictures}}
\end{figure}
\end{document}

Answer 1

您可以使用此设置：

\captionsetup[figure]{% use subfigure to confine changes to subcaptions
  justification = RaggedRight, % Or justified
  format=hang}

完整的例子如下：

\documentclass[authoryear, review]{elsarticle} 

\usepackage{graphicx}
\usepackage[font = footnotesize, labelfont=bf]{subcaption}
\usepackage[font = footnotesize, labelfont=bf]{caption}

\captionsetup[figure]{%
  justification = RaggedRight, % Or justified
  format=hang}

\begin{document}

\begin{figure}
    \centering
    \begin{subfigure}[b]{0.45\textwidth}
        \includegraphics[width=\textwidth]{example-image-A}
        \caption{This is a rather long sub-caption for this nice picture of sails}
    \end{subfigure}
    ~ 
    \begin{subfigure}[b]{0.44\textwidth}
        \includegraphics[width=\textwidth]{example-image-B}
        \caption{This is a rather long sub-caption for this nice picture of sails}
    \end{subfigure}
    \caption{\textbf{This is the overall caption for this group of sailing pictures}}
\end{figure}
\end{document}
