[css] 使用css画文件夹icon和话筒icon

在一些界面上,如果每个icon都去找图片还是相当麻烦的,直接使用css画出icon就方便的多了,下面两个是画的文件夹和话筒的icon

效果:

 

 文件夹:

.folderBtn {
    display: inline-block;
    background-color: transparent;
    overflow: hidden;
    font-size: 1px;
}
.folderBtn:before {
    content: '';
    float: left;
    background-color: #9da0a0;
    width: 15px;
    height: 3px;
    margin-left: 2px;
    border-top-left-radius: 2px;
    border-top-right-radius: 2px;
    box-shadow: 2px 2px 0 0 #9da0a0;
}
.folderBtn:after {
    content: : left;
    clear: left;
    background-color: #d4d6d6;
    width: 33px;
    height: 22px;
    border-radius: 1px;
}

话筒:

.audioIcon {
    color: #9da0a0;
    position: relative;
    width: 12px;
    height: 14px;
    border-left: solid 1px currentColor;
    border-right: solid 1px currentColor;
    border-bottom: solid 1px currentColor;
    border-radius: 50% 50%;
    display: inline-block;
}
.audioIcon:before {
    content: ;
    position: absolute;
    left: 1px;
    top: -6px;
    width: 8px;
    height: 17px;
    border: solid 1px currentColor;
    border-radius: 4px;
    background-color: currentColor;
}
.audioIcon:after {
    content: ;
    position: absolute;
    left: 4px;
    bottom: -4px;
    width: 1px;
    height: 4px;
    background-color: currentColor;
}
