                display:none; 
            }

想要更改此背景：

error on hover

Answer 1

这可以通过使用图像来实现：

/* CSS 2 */
#css2 i {
    position: absolute;
    right: 150px;
    border: solid 25px transparent;
    border-right-color: yellow;
} 

/* CSS 3 */
#css3 .content:before {
    content: "";
    position: absolute;
    right: 150px;
    border: solid 25px transparent;
    border-right-color: yellow;
}

/* The hover */
.container:hover .content {
    background: green;
}
#css2:hover i, #css3:hover .content:before {
    border-right-color: green;
}

DEMO：Here

这将在未来中更容易维持。

Answer 2

您正尝试更改子鼠标悬停时的父级css。这是不可能通过纯CSS。我建议你可以做相反的事情。在父母的悬停以及自己的

上更改孩子的背景

 ul.ui-tabs-nav li:hover{ 
    background: url('/themes/livramentolc/images/selected-item.png') top left no-repeat !Important;
}

ul.ui-tabs-nav li:hover a{
  background:#ffd503 !important;
}

当我将鼠标悬停在＃nav-fragment-1上时，我想更改#featured ul.ui-tabs-nav
