我希望在点击它后更改框的背景颜色,同时创建另一个带有纯CSS的框。我用目标选择器尝试了它。但我只能设法做其中一个而不是两个同时。
这是我尝试的DEMO。
/* fonts */
p {
font-size: 10px;
}
#school::after,
#work::after {
font-size: 10px;
content: "Second box";
color: white
}
/* white boxes */
.panel {
height: 50px;
width: 50px;
background-color: white;
border: 1px solid #262626;
position: relative;
}
/* span (100%, 100%) inside the white-boxes */
.panel span {
position: absolute;
width: 100%;
height: 100%;
top: 0;
left: 0;
}
/* second-box */
.panel div {
display: none;
}
/* if white-box is targeted, this lets the second-box appear */
.panel div:target {
display: block;
height: 50px;
width: 50px;
background-color: blue;
border: 1px solid black;
border-radius: 4px;
position: absolute;
left: 70px;
}
/* for testing purposes */
.panel:active span {
background-color: black;
}

<p>White Boxes</p>
<div class="panel">
<a href="#school">
<span></span>
</a>
<div id="school"></div>
</div>
<div class="panel">
<a href="#work">
<span></span>
</a>
<div id="work"></div>
</div>
&#13;

您可以使用:target
伪类修改任意数量的元素的表示形式,只要每个元素都嵌套在id
的元素中即可。 :target
ED:
/* fonts */
p {
font-size: 10px;
}
#school div::after, #work div::after {
font-size: 10px;
content: "Second box";
color: white
}
/* white boxes */
.panel {
height: 50px;
width: 50px;
background-color: white;
border: 1px solid #262626;
position: relative;
}
/* span (100%, 100%) inside the white-boxes */
.panel span {
position:absolute;
width:100%;
height:100%;
top:0;
left: 0;
}
/* second-box */
.panel a div {
display: none;
}
/* if white-box is targeted, this lets the second-box appear */
.panel a:target div {
display: block;
height: 50px;
width: 50px;
background-color: blue;
border: 1px solid black;
border-radius: 4px;
position: absolute;
left: 70px;
}
/* if white-box is targeted, this gives the box a blue background */
.panel a:target span {
background-color: blue;
}
/* for testing purposes */
.panel:active span {
background-color: black;
}
<p>White Boxes</p>
<div class="panel">
<a href="#school" id="school">
<span></span>
<div></div>
</a>
</div>
<div class="panel">
<a href="#work" id="work">
<span></span>
<div></div>
</a>
</div>

:target
仅适用于同一个元素,因为您无法同时定位两个锚点。你需要:checked
:checked
我做了什么:
<div class="panel">
<label>
<input type="checkbox">
<div></div>
</label>
</div>
CSS
label {
display:block;
position: relative;
width: 100%;
height: 100%;
}
label input {
visibility: hidden;
}
label input:checked + div {
display: block;
}

我看到答案已被接受,但如果其他人有兴趣,我会发布我的解决方案。
我将div的位置更改为链接之前并添加了css规则。
新代码:
.panel div:target+a span{
background-color: black;
}
CSS补充道:
backend/portfolio/{$id}
