10 定义的章节样式,如何将某些节点可动态根据上一个节点的大小,来适当调整上下的位置?

在定义好的样式中每一个节点都是写死了的固定位置。但是在使用时节点description的内容是不固定的,可能很长也可能很短。此时如何将description下方的objectives节点的位置可以动态调整,使其相差1cm。
这个是当前的效果图:

这是当前的代码:

\usepackage[explicit]{titlesec}

\usepackage[margin = 2cm]{geometry}
\usepackage{enumitem}
\usepackage{tikz}


\usepackage{graphbox} % provide align = c 

\makeatletter

只需以 description 节点为基点做平移即可

\documentclass{book}

\usepackage[explicit]{titlesec}

\usepackage[margin = 2cm]{geometry}
\usepackage{enumitem}

\usepackage{graphbox} % provide align = c

    \fill[gray!40] ([shift = {(2cm + .2\textwidth, -2.5cm)}]current page.north west) rectangle ++ (.8\textwidth, -4cm);
