大家好！这里我想要透明背景tcolorbox，当框进入框或页面颜色应用情况时。这里我使用了黄色背景框，所以我需要黄色背景，我无法将第二个框颜色变为透明。如果有任何选项可以使用更改背景颜色tcolorbox。请做必要的操作。
\documentclass[12pt]{article}
\RequirePackage[most]{tcolorbox}
\usetikzlibrary{patterns,shadows}
\newenvironment{Boxone}{\begin{tcolorbox}[colback=yellow!30,colbacklower=white,]
}{\end{tcolorbox}}
\newenvironment{Boxtwo}{\begin{tcolorbox}[colback=white,colbacklower=white]
}{\end{tcolorbox}}
\begin{document}
\begin{Boxone}
A patient asks you how many medicines they need to swallow to take all their morning medicines. They have the following medicines to take:
\begin{Boxtwo}

使用enhanced jigsaw和opacityback，您可以使其tcolorbox透明。顺便说一句，我不知道您为什么要colbacklower在这里使用...
\documentclass[12pt]{article}
\RequirePackage[most]{tcolorbox}
\usetikzlibrary{patterns,shadows}
\newenvironment{Boxone}{\begin{tcolorbox}[colback=yellow!30]
}{\end{tcolorbox}}
\newenvironment{Boxtwo}{\begin{tcolorbox}[opacityback=0,enhanced jigsaw]
}{\end{tcolorbox}}
\begin{document}
\begin{Boxone}
A patient asks you how many medicines they need to swallow to take all their morning medicines. They have the following medicines to take:
\begin{Boxtwo}

\end{document}
黄色框内：
不包含任何东西：
但是，你不应该使用（或者至少我不建议你使用）\newenvironment来定义一个新的tcolorbox。该包有一个宏。
\documentclass[12pt]{article}
\usepackage[most]{tcolorbox}
\usetikzlibrary{patterns,shadows}
\newtcolorbox{Boxone}{colback=yellow!30}
\newtcolorbox{Boxtwo}{opacityback=0,enhanced jigsaw}
\begin{document}
\begin{Boxone}
A patient asks you how many medicines they need to swallow to take all their morning medicines. They have the following medicines to take:
\begin{Boxtwo}
