• 用css3实现各种图标效果(2)


    写在前面

    写的一模一样的css样式,结果却导致原来出来不一样的效果图。

    用chrome的开发者工具查看,比较起来还是一模一样的css样式,可为什么会出现不一样的placeholder效果呢?一个白色粗体,一个灰色正常字体。

    找了老半天找不到原因

    后来才发现是我同事写的框架css里面代码的一句话影响到了

    ::-webkit-input-placeholder {
      color: #a4afc6;
    }

    可是为什么在chrome控制台看不到这句代码呢?请教了一番同事,原来是这样的。

     1、点击控制台“设置”按钮

    2、按如下所示设置,选中“Show user agent shadow DOM”

    3、你就会在elements控制面板里面能看到如下所示

    回归正题,继续我的css各种图标。。。。

    当然在开始之前,还是加上如下这段公共样式吧!

    [class^="u-icon"]
    {
        display: inline-block;
        color: #fff;
        vertical-align: middle;
    }

    各种删除按钮(不用图标只能css来实现)

    html代码如下:

        <span class="u-icon-radioDelete"></span>
        <span class="u-icon-deleteToggle Orange">
            <span class="u-icon-trash"></span>删除
        </span>
        <span class="u-icon-deleteToggle Blue">
            <span class="u-icon-grayTrash"></span>删除
        </span>
        <span class="u-icon-del"></span>
        <span class="u-icon-del on"></span>
        <span class='u-icon-sel more'>搜索更多</span>
        <span class='u-icon-sel on'>搜索更多</span>
        <span class='u-icon-delete'><i></i></span>

    页面显示效果如下:
