如果與其他尺寸的圖像和文字混合在一起，如何確保不同頁面上相同尺寸的文字在頁面頂部的距離相同

THIS TEXT NEEDS TO BE ALIGNED我的一頁上只有文本book，前面有一些vspace值。另一個頁面上還有一些WITH THIS TEXT文本，前面有一些vspace值、TEXT BEFORE TEXT THAT NEEDS TO BE ALIGNED不同大小的文本和example-image-c圖像。
我需要THIS TEXT NEEDS TO BE ALIGNED和WITH THIS TEXT與頁面頂部的距離完全相同，因此，如果兩個頁面堆疊在一起，兩個文字將彼此正確對齊。
在我當前的程式碼中，我分配ex values給文本，vspaces甚至分配給圖像的高度。我希望透過等於兩個文字之前的所有元素的垂直值總數，我將正確對齊所需的文字（與頁面頂部的距離相同），但事實並非如此！我究竟做錯了什麼？\begin{titlepage}其中一頁是否增加了一些我不知道的空間？

此方法使用包含「WITH THIS TEXT」上方材料的方塊來計算「THIS TEXT NEEDS TO BE ALIGNED」之前所需的垂直空間，以對齊兩個句子。

在群組內使用時\fontsize{}{}\selectfont，需要在關閉群組之前結束段落。

\selectfont雖然字體大小在發布新版本時更新，baselineskip但僅在段落使用 , 或空白行結束時更新\par。

看\fontsize{}{} 如何運作？
