Question

我正在制作一个个人网站，通过相应的图标链接到社交媒体。但是，该链接不可单击。

Answer 1

如果您希望a周围的整个div可点击，请使用display:inline-block

.icon a {
height: 100%;
width: 100%;
display: inline-block;
}

Answer 2

通过添加display:block对 CSS 进行以下更改

.icon a {
height: 100%;
width: 100%;
display: block;
}

Answer 3

您可以使用CSS:before伪元素，content属性设置为attr()函数，参数设置为 HTML 的data-*属性

<div class="linkedin icon"><a href="https://www.linkedin.com/in/mufeezamjad/" target="_blank" data-link="linkedin"></a></div>
<div class="github icon"><a href="https://www.github.com/mufeez-amjad" target="_blank" data-link="github"></a></div>
<div class="instagram icon"><a href="http://www.instagram.com/mufeez.a" target="_blank" data-link="instagram"></a></div>
<div class="twitter icon"><a href="https://www.twitter.com/mufeeza_" target="_blank" data-link="twitter"></a></div>

a:before {
content:attr(data-link);
}

JSFIDDLE https://jsfiddle.net/99ksjh9g/

使用 CSS:before伪元素，content设置为url()函数，data URL作为参数传递

.icon {
background-color: #363636;
background-repeat: no-repeat;
background-position: center center;
height: 50px;
width: 50px;
