Question

我已按照此Star rating widget with pure CSS教程，即使它在Chrome和Firefox中正常运行。点击Firefox中的星标时，页面会一直滚动到顶部。就像你用href ='＃'点击数据一样。

有关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>

这里是 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;
}

输入类型的无线电字段将被绝对移动到顶部-9999px。单击时，输入字段将被更改，Firefox将尝试滚动到它们。而不是移动尝试隐藏它们：

替换

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

与

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

单击Firefox时，纯CSS明星评级小部件专注于顶部
