这篇文章先讲几个重要的点,然后文末有效果图和具体代码
-
css优先级
<div class="column">
<div class="ui inverted segment card-view" style="background: url('img/card.png');background-size: cover;background-repeat: no-repeat;">
<h3 class="ui header">Title's here</h3>
<h4 class="ui header">Username</h4>
<div class="ui divider"></div>
<div class="ui red circular label">40%get</div>
<span>10k<i class="icon unhide"></i></span>
</div>
</div>
这里再介绍一种选择器,之前我们在修改时,为了防止修改一个标签而造成其他标签样式的改变,我们会给标签加一个别名,此外,我们也可以使用子孙选择器
.ui.vertical.basic.segment.recommended > .ui.center.aligned.header{
}
今天发现一个问题,就是css选择器不要留空格,比如以下这种方式是不对的
.ui .vertical .basic .segment .recommended{
}
需要改成无空格:
.ui.vertical.basic.segment.recommended{
}

栅格布局
1.定距
<div class="ui three column grid">
<div class="column">
</div>
<div class="column">
</div>
<div class="column">
</div>
</div>
2.定宽
<div class="ui grid">
<div class="four wide column">
</div>
<div class="four wide column">
</div>
<div class="four wide column">
</div>
<div class="four wide column">
</div>
</div>
