我想保留这个,除非链接在某个div内.

我尝试的代码(和几个变体)不起作用.

HTML：

<div class="wall-entry span5">
            <a href="">
            <img src="http://www.placehold.it/290x163" />
            <div class="wall-address">
                <p>Burgundy Street</p>
                <p>New Orleans,LA</p>
                <p>USA</p>
            </div>
            </a>
        </div>

我的CSS：

.wall-entry     {
                background-color: @black;
                position: relative;

            img {
                opacity:0.4;
                filter:alpha(opacity=40); /* For IE8 and earlier */
                }

            div {
                position: absolute;
                left: 10px;
                bottom: 10px;
                p   {
                    line-height: 18px;
                    margin: 0;
                    font-family: Neuzit Heavy;
                    font-size: 18px;
                    color: white;
                    text-decoration: none;
                    }
                }
            }


div.wall-entry:hover img    {
                            opacity:1;
                            filter:alpha(opacity=100); /* For IE8 and earlier */                    
                            }

a div.wall-entry {text-decoration: none;}

快速说明：我测试过{text-decoration：none;},这确实有效.但是,我不想改变一切.只是这个特定情况下的链接.
