Tcolorbox、xshift 和框的对称性

Tcolorbox、xshift 和框的对称性

我向颜色框添加了在 x 轴上移动的选项。

然而，出现了一个问题：盒子是对称的，当我将它向右移动时，左边也会向中心移动，使盒子变得非常小。如何消除这种影响？

这是代码（如果仍然有多余的内容，请告诉我。我想知道如何做 MWE）。

此外，我还有一个次要问题：我怎样才能稍微移动一下正方形（出现在 pdf 文档中）？我希望它位于框内，而不是像现在这样一半在框外。

答案1

你搞砸了一些东西，因为你在样式thmbox中使用了样式SQ，但它们具有相同的选项但具有不同的值，然后，你再次\newtcbtheorem使用它们两者进行了定义。

我把它们分开，即使为了方便，你也可以创建一个带有选项的样式，相同对于两种风格，然后将其用于thmbox和SQ，只添加选项不同对他们每个人来说。

对于文本末尾的方形符号，我使用了\qedforasmthm和此选项：after upper={\hfill$\qed$}。

我没有改变规则设置（但对我来说它也显得有点混乱），因为我仍然不明白你想要的最终外观是什么。
