我的页脚有问题:我希望div行中有3个居中的列。这是代码。
.col-1 {
float: left;
width: 20%;
padding: 5px;
height: 100px;
}
.col-2 {
float: left;
width: 40%;
padding: 5px;
height: 100px;
}

<footer>
<div class="row bg-black">
<div class="col-2">
<div class="social-box">
<div><p>Connect with us:</p></div>
<div>
<div><img src="assets/twitter.png" alt=""></div>
<div><img src="assets/linkedin.png" alt=""></div>
</div>
</div>
</div>
<div class="col-1">
<p>dsds</p>
</div>
<div class="col-1">
<p>dsds</p>
</div>
</div>
<div class="row"></div>
</footer> <!-- END FOOTER -->

如果我将float: left
放在列上,我的背景就不会显示为黑色。
我该如何解决这个问题?它也不适用于flex。
答案 0 :(得分:1)
使用flexbox将col元素居中并添加一些小样式以使行背景颜色变黑(元素需要一个大小来显示背景)
.row {
width: 100vmax;
height: 100px;
margin-left: -8px;
display: flex;
justify-content: center;
}
.bg-black {
background-color: black;
}
.col-1 {
color: white;
/*float: left;*/
width: 20%;
padding: 5px;
height: 100px;
}
.col-2 {
color: white;
/*float: left;*/
width: 40%;
padding: 5px;
height: 100px;
}
