我想要替換這個練習環境的小頁面設計。我最近了解到，小型頁面跨頁面邊界是牢不可破的。身為 TeX/LaTeX 程式系統的新手，我發現要掌握其內部結構有點困難。因此，我將不勝感激我能得到的任何幫助 - 我已經查看了幾個軟體包，例如 adjustmentwidth 和 tcolorbox，但收效甚微。
我希望得到的最終結果是一種演算法，可以幫助我的鍛鍊環境突破頁面邊界。我還要說的是，我對這個小組和這個網站還很陌生，所以我不知道積分系統是如何運作的。這是一個 MWE

Consider the set $[X,A]$, wher $A$ is a fixed space. Show that a continuous map $\fmap{f}X\to Y$ gives rise to a function $\fmap{f_{\bast}}[X,A]\to [Y,A]$ with the following properties.
\begin{enumerate}[align=left,leftmargin=*,label=(\roman*),widest=iii,font=\normalfont,topsep=0pt,nosep]
\item\label{12SimComExer39i} If $f\simeq g$, then $f_{\bast}=g_{\bast}$.
\item\label{12SimComExer39ii} If $\fmap{1}X\to X$ is the identity map, then $1_{\bast}$ is the identity function.
\item\label{12SimComExer39iii} If $\fmap{g}Y\to Z$ is another continuous map, then $(qf)_{\bast}=g_{\bast}f_{\bast}$.
\end{enumerate}
Deduce that if $X\simeq Y$ there is a $(1-1)$-correspondence between the sets $[X,A]$ and $[Y,A]$.\par
What are the corresponding results for the sets $[X,A]$, for a fixed space $A$?
