Html li背景色给孩子们同样的颜色

我有一些css使列表看起来像树视图。我正在尝试更改当前选定li的背景，但它也会将所有子项更改为该背景颜色。有没有办法避免这种情况发生

下面是基本树结构，我通过读取文件夹结构的代码ULScript和ULShader来填充它。为了进行测试，我刚刚将脚本li的背景设置为灰色，当加载其他li的脚本时，它们也都是灰色的

<div class="css-treeview" id="projectTree" style="display: none;">
            <ul>
                <li><input type="checkbox" id="projectRoot" /><label for="ProjectRoot" id="projectRootLabel">ProjectName</label>
                    <ul>
                        <li><input type="checkbox" id="Scripts" /><label for="Scripts">Scripts</label>
                            <ul id="ulScripts">
                            </ul>
                        </li>
                        <li><input type="checkbox" id="Shaders" /><label for="Shaders">Shaders</label>
                            <ul id="ulShaders">
                            </ul>
                        </li>
                    </ul>
                </li>
            </ul>
        </div>

Treeview css中，我也很想更改它，因此如果您单击标签，则需要单击dbl来扩展它，而不是像现在这样的单个标签。复选框部分仍然是一次单击

你能分享你的css吗？如果你正在使用javascript，我们可以进行故障排除。但是，快速浏览一下，LI中的任何内容都会有灰色背景，因为它包含在元素中。你总是可以让孩子改变颜色。“但它也会把所有的孩子都变成背景色”——不，不应该；背景色不是继承的。当然，您会看到父元素“shine through”的背景，所有未设置其自身背景的子元素。因此，每次单击时，我必须将所有背景设置为白色，然后仅将单击的1设置为灰色？这是一种有效的处理方法还是有更好的方法？
