标题紧贴边距，不悬挂

Question

我想让图形标题保留在第二行，从左边距开始。我正在使用subcaption包。请给我一个解决方案。

Answer 1

您可能已将format字幕的 设置为hang。使用 后效果如下hang：

\documentclass{article}

\usepackage{subcaption,graphicx}

\captionsetup{
  labelfont=bf,
  format=hang% <------------- Remove
}

\begin{document}

\begin{figure}
  \subcaptionbox{Original state}
    {\includegraphics[width=.3\linewidth]{example-image-a}}%
  \hfill
  \subcaptionbox{Longitudinal load}
    {\includegraphics[width=.3\linewidth]{example-image-b}}%
  \hfill
  \subcaptionbox{Transverse load}
    {\includegraphics[width=.3\linewidth]{example-image-c}}%

  \caption{Illustration of piezoelectric effect in a quartz crystal: (a)~Regular
    hexagonal crystal structure with electrodes. (b)~and (c)~Lattice
    distortion of the crystal generating field upon an
    applied mechanical force.}
\end{figure}

\end{document}

并且没有hang：
