我的页面左上角有1个大部分在屏幕外,它可以作为主页按钮。我想稍微增加它的大小,但我尝试的任何东西似乎都不起作用。
看到图像是一个矢量(感谢上帝)是一个完美的圆圈。因此,使用区域标签,我可以轻松地将其设为主页按钮。现在我想在悬停在该区域标签上时放大图像,我已尝试使用' +'选择器。
我该怎么做?
这是某些上下文的代码段:
.emblem {
width: 200px;
height: 200px;
position: absolute;
margin: -100px 0px 0px -80px;
z-index: 2;
opacity: 0.9;
}
.emblem:hover {
width: 220px;
height: 220px;
}
.emblem2 {
visibility: hidden;
width: 220px;
height: 220px;
}
area:hover + .emblem2 {
visibility: visible;
}

<map name="homemap">
<area shape="circle" coords="100,100,100" alt="Home button" href="index.html" />
</map>
<img class="emblem" src="https://placeholdit.imgix.net/~text?txtsize=33&txt=350%C3%97150&w=350&h=150" alt="UFF emblem" usemap="#homemap" />
<img class="emblem2" src="https://placeholdit.imgix.net/~text?txtsize=33&txt=350%C3%97150&w=350&h=150" alt="UFF emblem" usemap="#homemap" />

现在这种方法很好......但是只有当我将鼠标悬停在图像的透明部分上时,我想要达到的目标恰恰相反。

您可以尝试仅转换要放大的图像的比例。像这样的东西:
.emblem {
width: 200px;
height: 200px;
opacity: 0.9;
position: relative;
-webkit-transition: all 200ms ease-in;
-webkit-transform: scale(1);
-ms-transition: all 200ms ease-in;
-ms-transform: scale(1);
-moz-transition: all 200ms ease-in;
-moz-transform: scale(1);
transition: all 200ms ease-in;
transform: scale(1);
}
.emblem:hover{
-webkit-transition: all 200ms ease-in;
-webkit-transform: scale(1.5);
-ms-transition: all 200ms ease-in;
-ms-transform: scale(1.5);
-moz-transition: all 200ms ease-in;
-moz-transform: scale(1.5);
transition: all 200ms ease-in;
transform: scale(1.5);
}

使用CSS:
.img-box {
cursor: pointer;
height: 110px;
position: relative;
width: 110px;
}
.img-link {
color: #000;
text-decoration: none;
}
.img-link a,
.img-link a:active,
.img-link a:focus,
.img-link a:hover {
border-color: transparent;
color: #000;
text-decoration: none;
}
.fa-hover {
bottom: 0;
font-size: x-large;
position: absolute;
right: 0;
}
.fa-hover:hover + .emblem {
height: 100px;
width: 100px;
}
.emblem {
height: 75px;
width: 75px;
}
<link href="https://maxcdn.bootstrapcdn.com/font-awesome/4.7.0/css/font-awesome.min.css" rel="stylesheet"/>
<div class="img-box">
<a class="img-link" href="https://www.google.ca" target="_window">
<div class="fa-hover">
<span class="fa fa-plus"></span>
</div>
<img class="emblem" src="https://lh3.ggpht.com/A0x3jzuH1qRkE10HcTiT4qQr_6iAqVg-CTsoIqxnoIFyv92V91WI3KqiVlOvLtfoMRg=w300" />
</a>
</div>
在'+'选择器的下方是你的悬停元素必须高于'img'标签,但用css可以移动图标。
