具有此引导表:
<body leftmargin="0" topmargin="0" bgcolor="#ffffff" marginheight="0" marginwidth="0">
<div class="container-fluid h-100">
<div class="row float-right align-items-center" style="height: 5%;">
<div class="col-12">
langs
</div>
</div>
<div class="row w-100 text-center align-items-center" style="height: 85%;">
<div class="col-md-5">
hover1
</div>
<div class="col-md-2">
todo img
</div>
<div class="col-md-5">
hover2
</div>
</div>
<div class="row text-center align-items-center" style="height: 5%;">
<div class="col-12">
text end
</div>
</div>
</div>
</body>
我想知道何时将“ hover1” div悬停,是否有可能使用CSS,javascript,jQuery和html将所有表格背景更改为“ black”。
到目前为止,我尝试使用遗传类ex,例如.homeLeft:hover + .homeRight{}
来创建CSS,但是由于我将其更改为Bootstrap表,所以它不起作用。
任何帮助/提示都将不胜感激。

尝试这样的事情:
.parent-hover {
pointer-events: none;
}
.child-hover {
pointer-events: auto;
}
.parent-hover:hover {
background: yellow;
}
<link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/css/bootstrap.min.css" rel="stylesheet"/>
<div class="container-fluid h-100 parent-hover">
<div class="row float-right align-items-center" style="height: 5%;">
<div class="col-12">
langs
</div>
</div>
<div class="row w-100 text-center align-items-center" style="height: 85%;">
<div class="col-md-5 child-hover">
hover1
</div>
<div class="col-md-2">
todo img
</div>
<div class="col-md-5">
hover2
</div>
</div>
<div class="row text-center align-items-center" style="height: 5%;">
<div class="col-12">
text end
</div>
</div>
</div>
如果您希望多个孩子将父颜色更改为其他颜色,则可能必须使用javascript:
$(function(){
function changeTableColor(color) {
$(".parent").css("background-color", color);
}
$(".child-hover1").hover(function(){changeTableColor("yellow");});
$(".child-hover2").hover(function(){changeTableColor("red");});
$(".child-hover1").on("mouseleave", function(){changeTableColor("");});
$(".child-hover2").on("mouseleave", function(){changeTableColor("");});
});
