我已经使用纯 CSS教程遵循了这个 Star rating 小部件，即使它在 Chrome 和 Firefox 中都能正常工作。在 Firefox 中单击星号时，页面会一直滚动到顶部。就好像您正在单击带有 href='#' 的数据。

关于如何防止这种情况的任何想法？这是HTML：

<fieldset class="rating">
    <legend>Please rate:</legend>
    <input type="radio" id="star5" name="rating" value="5" /><label for="star5" title="Rocks!">5 stars</label>
    <input type="radio" id="star4" name="rating" value="4" /><label for="star4" title="Pretty good">4 stars</label>
    <input type="radio" id="star3" name="rating" value="3" /><label for="star3" title="Meh">3 stars</label>
    <input type="radio" id="star2" name="rating" value="2" /><label for="star2" title="Kinda bad">2 stars</label>
    <input type="radio" id="star1" name="rating" value="1" /><label for="star1" title="Sucks big time">1 star</label>
</fieldset>

这是CSS：

.rating {
    float:left;
}

/* :not(:checked) is a filter, so that browsers that don’t support :checked don’t
   follow these rules. Every browser that supports :checked also supports :not(), so
   it doesn’t make the test unnecessarily selective */
.rating:not(:checked) > input {
    position:absolute;
    top:-9999px;
    clip:rect(0,0,0,0);
}

.rating:not(:checked) > label {
    float:right;
    width:1em;
    padding:0 .1em;
    overflow:hidden;
    white-space:nowrap;
    cursor:pointer;
    font-size:200%;
    line-height:1.2;
    color:#ddd;
    text-shadow:1px 1px #bbb, 2px 2px #666, .1em .1em .2em rgba(0,0,0,.5);
}

.rating:not(:checked) > label:before {
    content: '★ ';
}

.rating > input:checked ~ label {
    color: #f70;
    text-shadow:1px 1px #c60, 2px 2px #940, .1em .1em .2em rgba(0,0,0,.5);
}

.rating:not(:checked) > label:hover,
.rating:not(:checked) > label:hover ~ label {
    color: gold;
    text-shadow:1px 1px goldenrod, 2px 2px #B57340, .1em .1em .2em rgba(0,0,0,.5);
}

.rating > input:checked + label:hover,
.rating > input:checked + label:hover ~ label,
.rating > input:checked ~ label:hover,
.rating > input:checked ~ label:hover ~ label,
.rating > label:hover ~ input:checked ~ label {
    color: #ea0;
    text-shadow:1px 1px goldenrod, 2px 2px #B57340, .1em .1em .2em rgba(0,0,0,.5);
}

.rating > label:active {
    position:relative;
    top:2px;
    left:2px;
}

输入类型单选字段将绝对移动到顶部 -9999px。单击时，输入字段将被更改，Firefox 会尝试滚动到它们。而不是移动尝试隐藏它们：

代替

.rating:not(:checked) > input {
    position:absolute;
    top:-9999px;
    clip:rect(0,0,0,0);
}

和

.rating:not(:checked) > input {
    display: none;
}
