CSS speech bubble with Box Shadow

advertisements

Creating a DIV that uses CSS to draw a triangle to the left. Trying to apply a uniform box-shadow to both parent and the pseudo element (see images) and code.

Is this possible? Or am I better off using border-image for this?

(Top: Before Shadow, Middle: CSS Box-Shadow, Bottom: Desired Result)

.bubble{
    height: 200px;
    width:  275px;

    opacity: 0;

    margin-top: 41px;

    float: right;

    background-color: #F2F2F2;

    -webkit-border-radius: 5px;
    -webkit-box-shadow: 0px 0px 6px #B2B2B2;
}

.bubble::after {
        height: 0px;
        width:  0px;

        content: "\00a0";

        display: block;

        margin-left: -10px;
        margin-top:   28px;

        border-width: 10px 10px 10px 0;
        border-style: solid;
        border-color: transparent #F2F2F2 transparent transparent;

        -webkit-box-shadow: 0px 0px 6px #B2B2B2;
    }


Instead of using a triangle hack, you can just rotate a div using transform and get a real box-shadow. Since you only want the shadow on one side of the div (the visible triangle side), you have to make the blur smaller and lower the opacity.

HTML:

<div class="bubble"></div>

CSS:

.bubble{
    background-color: #F2F2F2;
    border-radius: 5px;
    box-shadow: 0px 0px 6px #B2B2B2;
    height: 200px;
    margin: 20px;
    width:  275px;
}

.bubble::after {
    background-color: #F2F2F2;
    box-shadow: -2px 2px 2px 0 rgba( 178, 178, 178, .4 );
    content: "\00a0";
    display: block;
    height: 20px;
    left: -10px;
    position: relative;
    top: 20px;
    transform:             rotate( 45deg );
        -moz-transform:    rotate( 45deg );
        -ms-transform:     rotate( 45deg );
        -o-transform:      rotate( 45deg );
        -webkit-transform: rotate( 45deg );
    width:  20px;
}

Output:
