我正在使用CSS计数器和嵌套OL在HTML / CSS中创建目录,这非常有用。现在,我想在顶级OL上设置一个类“toc”(因为页面上有更多的OL而不仅仅是目录)。
如何调整CSS选择器以使计数器样式仅适用于<ol class="toc">
?
如果从第一个OL中删除class =“toc”,你会看到项目编号按照你的预期嵌套...当你添加toc类时,它都会进入底池。如何修复css选择器以使嵌套项目编号按预期工作?
<style>
ol {
counter-reset: section; /* Creates a new instance of the
section counter with each ol
element */
list-style-type: none;
text-decoration:underline;
}
li:before {
counter-increment: section; /* Increments only this instance
of the section counter */
content: counters(section, ".") " "; /* Adds the value of all instances
of the section counter separated
by a ".". */
font-weight:bold;
}
</style>

<style>
ol { color:black; }
ol.parentol { color:red; }
ol.childol { color:green; }
/* nested ols with class of 'childol'
will not inherit the red font color */
