以水平佈局命名的錨點

Question

在我正在開發的站點中，我有一堆不同大小的圖像以水平佈局佈置。我也有一些命名的錨鏈接，可以在點擊時跳轉到特定的圖像。如果點擊鏈接，我需要將所選圖像放在頁面的中心，而不是最後。有沒有辦法給錨點添加一些負偏移量？

在此先感謝

CSS：

.carousel-frame { 
    width: 100%; 
    margin-bottom: 0.5em; 
    padding-bottom: 1em; 
    position: relative; 
    white-space: nowrap; 
} 
.carousel-frame ul { 
    margin: 0; 
    padding: 0; 
    height: 100%; 
    list-style: none; 
} 
.carousel-frame li.carousel-item { 
    cursor: pointer; 
    display: inline-block; 
    margin: 0 5px 0 0; 
    padding: 0; 
} 
.carousel-frame li.carousel-item span {

您可以使用animate：

$('a[href^="#item-"]').on('click', function(e) { 
 
    e.preventDefault(); 
 

 
    // select the carousel-frame 
 
    var divCarousel = $('.carousel-frame'); 
 

 
    // select the corresponding carousel-item 
 
    var objToMove = divCarousel.find(this.getAttribute('href')); 
 

 
    // compute the new left position 
 
    var newPos = (objToMove.position().left - divCarousel.width()) + (divCarousel.width() + objToMove.width())/2; 
 

 
    // move to the new position 
 
    divCarousel.animate({left: -newPos}, 2000); 
 
})

.carousel-frame { 
 
    width: 100%; 
 
    margin-bottom: 0.5em; 
 
    padding-bottom: 1em; 
 
    position: relative; 
 
    white-space: nowrap; 
 
} 
 
.carousel-frame ul { 
 
    margin: 0; 
 
    padding: 0; 
 
    height: 100%; 
 
    list-style: none; 
 
} 
 
.carousel-frame li.carousel-item { 
 
    cursor: pointer; 
 
    display: inline-block; 
 
    margin: 0 5px 0 0; 
 
    padding: 0; 
 
} 
 
.carousel-frame li.carousel-item span { 
 
    display: block; 
 
} 
 

 
a { 
 
    text-decoration: none; font: menu; 
 
    display: inline-block; padding: 2px 8px; 
 
    background: ButtonFace; color: ButtonText; 
 
    border-style: solid; border-width: 2px; 
 
    border-color: ButtonHighlight ButtonShadow ButtonShadow ButtonHighlight; 
 
}
