TikZ Tree：更改特定树边的样式

Question

我想改变树的某些边的样式。我想要一条从根到树的一片叶子的红色虚线路径。但是如果我改变某些特定的边，下面的所有边也会改变。甚至标签也变成红色，这不是我想要的。

因此发生了以下事情：

但我想要这样的东西：

有什么建议吗？这应该不难。但我花了一个多小时才找到答案。这是我的代码：

\documentclass[border=10pt,svgnames]{standalone} 

\usepackage{tikz}
\usetikzlibrary{positioning,automata,backgrounds}
\definecolor{light-gray}{gray}{0.6}


\begin{document}
\centering
\begin{tikzpicture}[level distance=1.5cm,
  level 1/.style={sibling distance=3cm},
  level 2/.style={sibling distance=1cm},
  level 3/.style={sibling distance=1cm},
  every node/.style={thin}]
  \node {1}
    child {node {00}
      child {node {00}}
      child {node {}}
      child {node {10}}
      child {node {}}
    }
    child {node {}}
    child {node {10}
    child {node {00} edge from parent[dashed, very thick, red]
    child {node {00}}  
    child {node {01}}
    child {node {10}}
    child {node {11} edge from parent[dashed, very thick, red]}
    }
    child {node {}}
    child {node {}}
    child {node {11}}
    }
    child {node {}};
\end{tikzpicture}
\end{document}

Answer 1

您可以使用Forest使用简单的语法包来定制树的每个边，只需插入这样的边选项

edge={dashed,red,thick}

完整代码

\documentclass[border=10pt,svgnames]{standalone} 
\usepackage{forest}

\begin{document}

\begin{forest}
for tree={delay={where content={}{content={\phantom{00}}}{}},s sep+=5mm,l+=5mm}
[1
  [00
     [00]
     []
     [10]
     []  
  ]
  []
  [10,edge={dashed,red,thick} 
     [00,edge={dashed,red,thick}
        [00]
        [01]
        [10]
        [11,edge={dashed,red,thick}]     
     ]
     []
     []
     [11]  
  ]
  [\phantom{00}]
]
\end{forest}

\end{document}
