悬停星级无法正常工作

Question

所以我在 codepen (https://codepen.io/anon/pen/Edzxaj) 上找到了以下代码来进行星级评分，这对于 Font Awesome 3.x 和 4.x 工作正常，但在 5.x 上悬停时无法产生相同的结果星星。

/* Base setup */
@import url(//use.fontawesome.com/releases/v5.4.2/css/all.css);

/* Ratings widget */
.rate {
    display: inline-block;
    border: 0;
}
/* Hide radio */
.rate > input {
    display: none;
}
/* Order correctly by floating highest to the right */
.rate > label {
    float: right;
}
/* The star of the show */
.rate > label:before {
    display: inline-block;
    font-size: 1.1rem;
    padding: .3rem .2rem;
    margin: 0;
    cursor: pointer;
    font-family: 'Font Awesome 5 Free';
    font-weight: 900;
    content: "\f005"; /* full star */
}

/* Half star trick */
.rate .half:before {
    content: "\f089"; /* half star no outline */
    position: absolute;
    padding-right: 0;
}

/* Click + hover color */
input:checked ~ label, /* color current and previous stars on checked */
label:hover, label:hover ~ label { color: #73B100;  } /* color previous stars on hover */

/* Hover highlights */
input:checked + label:hover, input:checked ~ label:hover, /* highlight current and previous stars */
input:checked ~ label:hover ~ label, /* highlight previous selected stars for new rating */
label:hover ~ input:checked ~ label /* highlight previous selected stars */ { color: #A6E72D;  } 

<fieldset class="rate">
    <input type="radio" id="rating10" name="rating" value="10" /><label for="rating10" title="5 stars"></label>
    <input type="radio" id="rating9" name="rating" value="9" /><label class="half" for="rating9" title="4 1/2 stars"></label>
    <input type="radio" id="rating8" name="rating" value="8" /><label for="rating8" title="4 stars"></label>
    <input type="radio" id="rating7" name="rating" value="7" /><label class="half" for="rating7" title="3 1/2 stars"></label>
    <input type="radio" id="rating6" name="rating" value="6" /><label for="rating6" title="3 stars"></label>
    <input type="radio" id="rating5" name="rating" value="5" /><label class="half" for="rating5" title="2 1/2 stars"></label>
    <input type="radio" id="rating4" name="rating" value="4" /><label for="rating4" title="2 stars"></label>
    <input type="radio" id="rating3" name="rating" value="3" /><label class="half" for="rating3" title="1 1/2 stars"></label>
    <input type="radio" id="rating2" name="rating" value="2" /><label for="rating2" title="1 star"></label>
    <input type="radio" id="rating1" name="rating" value="1" /><label class="half" for="rating1" title="1/2 star"></label>
</fieldset>

使用之前版本的 font awesome，将鼠标悬停在星形的后半部分会填满星形。在 5.x 中，您需要将光标一直悬停到星号的末尾，然后才能被填充（我知道这听起来有点模糊，但只需比较 codepen 和此示例即可了解悬停时的差异）。 有没有办法解决这个问题？

Answer 1

我能够通过将星形容器“切成”两半来解决这个问题。角色周围的额外空间导致悬停看起来不正确。

需要注意的是，这需要设置一个宽度，这可能会或可能不会成为问题，具体取决于您的实现。

.half 获得大约一半的完整星形宽度，然后overflow:hidden 删除多余的一半，margin-right 将星形移回左侧。它还为两个显示器使用了完整的星形图标，以便更好地排列。

.rate {
    display: inline-block;
    border: 0;

/* Hide radio */

.rate > label {
    float: right;
}
/* The star of the show */

    display: inline-block;

    padding: .3rem .2rem;
    margin-right:0;
    cursor: pointer;
    font-family: 'Font Awesome 5 Free';
    font-weight: 900;
    content: "\f005"; /* full star */
}

/* Half star trick */
.rate .half:before {
    content: "\f005"; /* half star no outline */
    position: absolute;
    padding-right: 0;
    width: 0.6rem;
    overflow: hidden;
    margin-right: 0.4rem;
}

/* Click + hover color */
input:checked ~ label, /* color current and previous stars on checked */
label:hover, label:hover ~ label { color: #73B100;  } /* color previous stars on hover */

/* Hover highlights */
input:checked + label:hover, input:checked ~ label:hover, /* highlight current and previous stars */
input:checked ~ label:hover ~ label, /* highlight previous selected stars for new rating */
label:hover ~ input:checked ~ label /* highlight previous selected stars */ { color: #A6E72D;  }
