CSS Box Shadow Bottom Only [duplicate]

问题

How can I do this? I want my element to look as though it has a shadow underline. I don't want the shadow for the other 3 sides.

回答1:

Do this:

box-shadow: 0 4px 2px -2px gray;

It's actually much simpler, whatever you set the blur to (3rd value), set the spread (4th value) to the negative of it.

You can use two elements, one inside the other, and give the outer one overflow: hidden and a width equal to the inner element together with a bottom padding so that the shadow on all the other sides are "cut off"

#outer {
    width: 100px;
    overflow: hidden;
    padding-bottom: 10px;
}

#outer > div {
    width: 100px;
    height: 100px;
    background: orange;

    -moz-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    -webkit-box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
    box-shadow: 0 4px 4px rgba(0, 0, 0, 0.4);
}

Alternatively, float the outer element to cause it to shrink to the size of the inner element. See: http://jsfiddle.net/QJPd5/1/

Try this

-moz-box-shadow:0 5px 5px rgba(182, 182, 182, 0.75);
-webkit-box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);
box-shadow: 0 5px 5px rgba(182, 182, 182, 0.75);

try this to get the box-shadow under your full control.

    <html>

    <head>
        <style> 
            div {
                width:300px;
                height:100px;
                background-color:yellow;
                box-shadow: 0 10px black inset,0 -10px red inset, -10px 0 blue inset, 10px 0 green inset;
           }
        </style>
    </head>
    <body>
        <div>
        </div>
    </body>

    </html>

this would apply to outer box-shadow as well.
