Question

我有以下HTML代码：

<div class="trial1">
He said all but the three newest reactors will be shut down by 2021, and the remainder a year later.Roettgen announced the agreement early on Monday morning after hour-long negotiations between the governing parties.Merkel in 2010 had pushed through to extend the lifespan of the country's 17 reactors with the last one scheduled to go offline in 2036, but she completely reversed her policy in the wake of Japan's nuclear disaster. She described the new move as a step that will make her country a pioneer in renewable energy.

<h1>This is h1</h1>

    <div class="trial2">
     this is something else what ever what ever
     </div>
</div>

我有以下css：

.trial1
{
    position:relative;
}
.trial2
{
    display:none;
    position:absolute;
    z-index:20;
    top:1;
    left:1;
    width:30px;
    height:30px;
}
.trial1:hover>.trial2
{
    display:block;
}
.trial1:hover>h1
{
    color:red;
}

每当trial1中的内容悬停时，我都希望显示trail2中的内容。但不知怎的，这不会发生。在同一元素悬停时改变h1颜色的类似过渡是有效的吗？我做错了什么？

Answer 1

缺少.

.trial1:hover>.trial2

悬停状态不影响显示属性
