如何在其他 beamer 主题中获取 boadilla 主题的块样式

Question

我想要 Boadilla 主题的块样式和默认主题。我遇到了这个问题，这对我很有帮助。但我想进一步自定义框，比如我想给块添加边框。这是 MWE

\documentclass[aspectratio=169]{beamer}
\usetheme{default}
\usepackage[most]{tcolorbox}

\setbeamertemplate{blocks}[rounded][shadow=true]
\setbeamercolor{block body example}{bg=red!20!white}
\setbeamercolor{block title example}{fg=red, bg=red!40!white}
% \definecolor{bitsdeepBlue}{RGB}{42, 42, 134}

\newtcolorbox{resp}[1][]{%
    enhanced jigsaw,%
    colback=red!20!white!90!,%
    colframe=red!85!white!90!,%
    colbacktitle=red!45!white!90!,
    % size=small,%
    % boxrule=1pt,%
    title=\textbf{\textit{Example}},%
    halign title=flush left,%
    coltitle=red,%
    breakable,%
    drop fuzzy shadow=black!70!white,%
}

\begin{document}
\begin{frame}{Frame Title}
\begin{example}
    this is default.
    \end{example}
    \begin{resp}
    this is what I am able to get
    \end{resp}
\end{frame}
\end{document}

这给我但是块稍微小了一点，阴影也不一样。我甚至不想在标题和正文混合的地方有边框。只要有外边框就可以了。而且块标题没有完全左对齐。

有人能帮我吗？谢谢

Answer 1

• 您可以使用以下方式将标题（和内容）进一步向左移动left=0pt
• 删除标题和正文之间的规则：titlerule=0pt
• 调整高度top=1pt和bottom=0pt
• 得到相同的块宽度：enlarge left by=-0.1cm和grow to right by=0.21cm

使用新的 tcolorbox 内部主题（https://www.ctan.org/pkg/beamertheme-tcolorbox)，现在使用 tcolorboxes 复制 beamer 块的外观和感觉变得更加容易：

\documentclass[aspectratio=169]{beamer}

\setbeamercolor{block body example}{bg=red!20!white, fg=black}
\setbeamercolor{block title example}{fg=red, bg=red!40!white}

\useinnertheme[shadow,rounded]{tcolorbox}

\tcbset{
 boxrule=1pt,
 frame style={draw,red!85!white}
}
   
\begin{document}
\begin{frame}{Frame Title}
\begin{example}
    this is default.
\end{example}
\end{frame}
\end{document}
