如何修改我的CSS，所以

• 将箭头移到底部并在蓝色箭头的左边添加一个灰色箭头。

Answer 1

这应该让你关闭。作为提示，我会分开您的:before和:after选择器属性，以便更清楚地将哪些规则应用于每个属性。

html{ 
 
    height:100%; 
 
} 
 
body{ 
 
    height:100%; 
 
    -moz-box-sizing:border-box; 
 
    box-sizing:border-box; 
 
    padding:20px; 
 
    background: #FFF; 
 
} 
 
[class^="folded-corner-"]{ 
 
    color: #444; 
 
    position:relative; 
 
    width:350px; 
 
    background:#E4E4E4; 
 
    margin-bottom:10px; 
 
    -webkit-box-shadow: 0px 0px 5px 0px rgba(0,0,0,0.3); 
 
    -moz-box-shadow: 0px 0px 5px 0px rgba(0,0,0,0.3); 
 
    box-shadow: 0px 0px 5px 0px rgba(0,0,0,0.3); 
 
} 
 
[class^="folded-corner-"], 
 
[class^="folded-corner-"]:before{ 
 
    min-height:100px; 
 
    right: 20px; 
 
    -webkit-box-sizing:border-box; 
 
    -moz-box-sizing:border-box; 
 
    box-sizing:border-box; 
 
} 
 
[class^="folded-corner-"]:before, 
 
[class^="folded-corner-"]:after{ 
 
    position:absolute; 
 
    content:""; 
 
    display:block; 
 
    position:absolute; 
 
    bottom:0; 
 
    margin-right: 20px; 
 
    width:0px; 
 
    height:0px; 
 
    box-sizing: border-box; 
 
    border-style:solid; 
 
} 
 
[class^="folded-corner-"] p{ 
 
    padding:20px; 
 
    color:#444; 
 
    font-size:12px; 
 
} 
 

 

 
.folded-corner-topright:before{ 
 
    border-width:0px 0px 20px 20px; 
 
    border-color:transparent transparent #d7d7d7 transparent; 
 
    right: 0px; 
 
} 
 
.folded-corner-topright:after{ 
 
    right:-20px; 
 
    border-width:20px 20px 0px 0px; 
 
    border-color:#0099E7 #fff transparent transparent; 
 
    box-shadow:3px 3px 2px 2px #FFF; 
 
}

<div class="folded-corner-topright"> 
 
    <p>JUST ANOTHER TEXT</p> 
 
</div>
