CSS功能区上的三角形阴影

Question

I am trying to replicate as pixel perfect as I can get and im having trouble trying to do the shadow on the right. Is this possible with css?

CSS:

*{margin:0px;padding:0px;}

html {
    width:100%;
        height:100%;
      text-align: center;
    }

.bold {
    font-weight:700;
}

#ribbon {
        padding: .34em 1em;
        margin: 0;
        margin-top: 5%;
        position:relative;
        color: #000;
        text-align: center;
        letter-spacing:0.1em;
        padding-top:12px;
        padding-bottom:12px;
        display: inline-block;
        background: #ffd82b;
        z-index:100;
        box-shadow: 0 7px 0px -2px #ebeced;
    }

#ribbon:after {
        content: "";
        width:3.2em;
        bottom:-.5em;
        position:absolute;
        display:block;
        border: .9em solid #ffd82b;
        box-shadow: 0 7px 0px -2px #ebeced;
        z-index:-2;
    }

#ribbon:after {
        right: -4.3em;
        border-left-width: .75em;
        border-right-color:transparent;
    }

#content:after {
        content:"";
        bottom:-.5em;
        position:absolute;
        display:block;
        border-style:solid;
        border-color: #fc9f42 transparent transparent transparent;
        z-index:-1;
    }
#content:before {
    content:"";
        top:-.5em;
    transform: rotate(90deg);
        position:absolute;
        display:block;
        border-style:solid;
        border-color: #fc9f42 transparent transparent transparent;
        z-index:-1;
}

#content:before {
      left: 0;
      border-width: .5em 0 0 .5em;
    }

#content:after {
      right: 0;
      border-width: .5em .5em 0 0;
    }

HTML:

<div id="ribbon">
    <span id="content"><span class="bold">Special Offer:</span> Recieve bonus rewards points for signing up</span>
</div>

Answer 1

You can make this ribbon without using box-shadows, only with borders, z-index and pseudo elements :

DEMO

output :

 .ribbon{ font-size:20px; position:relative; display:inline-block; margin: 2em 1em; text-align:center; } .text{ display:inline-block; padding:0.5em 1em; min-width:20em; line-height:1.2em; background: #FFD72A; position:relative; } .ribbon:after,.ribbon:before, .text:before,.text:after, .bold:before{ content:''; position:absolute; border-style:solid; } .ribbon:before{ top:0.3em; left:0.2em; width:100%; height:100%; border:none; background:#EBECED; z-index:-2; } .text:before{ bottom:100%; left:0; border-width: .5em .7em 0 0; border-color: transparent #FC9544 transparent transparent; } .text:after{ top:100%; right:0; border-width: .5em 2em 0 0; border-color: #FC9544 transparent transparent transparent; } .ribbon:after, .bold:before{ top:0.5em;right:-2em; border-width: 1.1em 1em 1.1em 3em; border-color: #FECC30 transparent #FECC30 #FECC30; z-index:-1; } .bold:before{ border-color: #EBECED transparent #EBECED #EBECED; top:0.7em; right:-2.3em; } 

 <p class="ribbon"> <span class="text"><strong class="bold">Special Offer:</strong> Recieve bonus rewards points for signing up</span> </p>

What if you add a new element to create missing shadow?

#abc {
    display:inline-block;       
    border: .9em solid #ebeced;
    border-right-color:transparent;
    position:absolute;
    right:-73px;
    z-index:-3;
    bottom:-12px;
}

another solution, use span:after inside #content

#content span:after {
    content:'';
    display:block;      
    border: .9em solid #ebeced;
    border-right-color:transparent;
    position:absolute;
    right:-73px;
    z-index:-3;
    bottom:-12px;
}
