悬停时更改元素的背景颜色 css

Question

我有一些 HTML 和 CSS 组成一个矩形。本质上我想做的是当你将鼠标悬停在正方形上时它会改变颜色。我已经试过了，但是没有用。

这是该元素的 HTML：

<div id="teamspeak_box"><a href="ts3server://craft412.serveminecraft.net:9987">
                                                                                                </div>

                   <div id="teamspeak_box_2"></div>

                   <div id="teamspeak_text">
                                   <p>TEAMSPEAK<P/>
                               </div>


                   <div id="teamspeak_image"> 
                                           <img src="images/CRAFT412 - Box - Teamspeak.png" alt="TEAMSPEAK">
                                      </div>

这里还有CSS

#teamspeak_box a:hover {background: #C62828;
                        transition: all 0.5s ease;}

#teamspeak_text {color: white;
                 bottom: 93px;
                 right: 66px;
                 position: absolute;}          

#teamspeak_image {bottom: 80px;
                  right: 104px;
                  position: absolute;}

#teamspeak_box {width: 159px;
                height: 43px;
                background: #212121;
                bottom: 82px;
                right: 76px;
                position: absolute;
                border-radius: 0px 0px 5px 5px;}

#teamspeak_box_2 {width: 43px;
                  height: 43px;
                  background:#313131;
                  bottom: 82px;
                  right: 191px;
                  position: absolute;
                  border-radius: 0px 0px 0px 5px;}

将您的 HTML/CSS 更改为此（如果这正是您要找的）

#teamspeak_box {
    display: block;
    width: 159px;
    height: 43px;
    background: #212121;
    position: absolute;
    top: 0;
    right: 76px;
    border-radius: 0px 0px 5px 5px;
    transition: all 0.5s ease;
}
#teamspeak_box:hover {
    background: #C62828;
}
#teamspeak_box a {
    display: block;
    height: 43px;
}
#teamspeak_box_2 {
    display: block;
    width: 43px;
    height: 43px;
    background:#313131;
    position: absolute;
    left: 0;
    top: 0;
    border-radius: 0px 0px 0px 5px;
}
#teamspeak_image {
    display: block;
    position: absolute;
    top: 5px;
    left: 5px;
}
#teamspeak_text {
    display: block;
    color: white;
    position: absolute;
    top: 14px;
    right: 10px;
    font-size: 16px;
    font-family:arial;
}

<div id="teamspeak_box">
    <a href="ts3server://craft412.serveminecraft.net:9987">
        <span id="teamspeak_box_2"></span>
        <span id="teamspeak_text">TEAMSPEAK</span>
        <img  id="teamspeak_image" src="//dummyimage.com/33x33" alt="TEAMSPEAK"/>
    </a>
</div>
