代码的作用如下：

这就是我要的：

在此处输入图片描述

我想用 tcolorbox 创建一个新环境或一个框，这样我就可以做你在图片中看到的事情。这个数学问题环境将有一个部分来解释问题陈述（可能长于一行），然后放一张问题的图片，或者添加额外的信息，最后是解决方案的一部分，其中有一些方形帮助行（如笔记本）来写解决方案。还想知道你是否可以用 pgfplot 制作一个具有透明背景的图形。抱歉我的英语不好，谢谢大家。

如果环境可以被打破，那么如果问题大于一页，那就太棒了

答案1

不完全符合您的图像，但可能是进行进一步调整的起点：

    lower separated=false, 
    before lower = {\tcbsubtitle[colback=white, colframe=black, boxrule=1pt, height=1cm,  width=2.55cm, valign=center]{Solution:}}
}

我已经问过与此相关的另一个问题，另一个问题有我想要的代码，所以这里是该答案的链接：

可破坏的 tcolorbox 解决了我的问题

如果您想要相同的盒子但可破碎，请勾选此项
