我天真地以为这将是一个简单的修复突出显示文本的方法 - 是的，有ulem.sty，soul.sty但它们施加了一些我不想处理的限制。

我认为使用类似的东西会很有用tikzmarks。事实确实如此，除了阴影矩形，虽然表面上看起来背景层，实际上是叠印了它们应该突出显示的文本。

这能行吗？我错过了什么？（使用 TexLive2022，昨天用 Aquamacs/Skim 更新）。我应该指出，这将始终在单个页面上使用。

我修改了文本以表明代码必须处理的一般问题（显示数学、小tikz对象）。到目前为止，所有回复（@samcarter_is_at_topanswers.xyz 和 @Qrrbrbirlbel）都完美地解决了这个问题。

您不需要尝试将 tikzpicture 放入背景中，而是可以将其留在文本上方并进行更改，blend mode以使文本仍然可见：

\usepackage{tikzpagenodes}

\usetikzlibrary{backgrounds}

PGF 层仅适用于图片本身，它仍然放在文本之上（因为您在最后绘制它）。

然后我们在文本前画出来。这里，tikzmark库确实提供了有用的宏

\iftikzmark{<name>}{<true>}{<false>}

你可以用它测试是否<name>已经存在（即不是在第一次编译运行时）然后执行适当的参数。

\iftikzmarkoncurrentpage如果您想检查结尾是否可能在另一页上，该库还提供...

这里我只在段落末尾使用了一个标记，开头不需要标记，我们可以直接从中抽取(0, 0)。\pgfmark只需要一个标记，因为我们不用这个标记做任何事情，只是保存它的位置。这样开销就小了一点。

由于或多或少插入了高度和深度\strut的不可见规则， 因此我将在答案中直接使用这些值。显然，如果您在开头和结尾使用不同的字体（大小），这将不再令人满意。.7\baselineskip.3\baselineskip

如果您能够切换到 lualatex，您可以使用该lua-ul包。此包避免了 soul 或 ulem 等类似包的大部分限制。

% !TeX TS-program = lualatex
