可点击区域增加的输入范围

Question

我正在尝试使用窄跟踪器和小拇指编写输入范围，但可点击区域比跟踪器更宽。

<div class="slider-wrapper">
  <input type="range" orient="vertical" class="volume-slider"/>
</div>

例如，我有一个用于输入范围的 div.slider-wrapper 包装器，当我在包装器内单击时，输入值会发生变化。

jsfiddle

我检查了rangeslider.js 和jquery ui slider，但没有找到解决方案。

.slider-wrapper{
  background: rgba(0, 0, 0, 0.8);
  width: 40px;
  height: 100px;
  position: relative;
  left: 1px;
}

input[type=range] {
    /*removes default webkit styles*/
    -webkit-appearance: none;

    /*fix for FF unable to apply focus style bug */
    /*border: 1px solid white;*/

    /*required for proper track sizing in FF*/
    width: 80px;

    transform: rotate(270deg);

    position: relative;
    left: -22px;
    top: 37px;
}
input[type=range]::-webkit-slider-runnable-track {
    width: 80px;
    height: 2px;
    background: #61b4f7;
    border: none;
    /*border-radius: 2px;*/
}

input[type=range]::-webkit-slider-thumb {
    -webkit-appearance: none;
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
    margin-top: -4px;
}

input[type=range]:focus {
    outline: none;
}

input[type=range]:focus::-webkit-slider-runnable-track {
    background: #ccc;
}

input[type=range]::-moz-range-track {
    width: 80px;
    height: 2px;
    background: #61b4f7;
    border: none;
    /* border-radius: 3px; */
}
input[type=range]::-moz-range-thumb {
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
}

/*hide the outline behind the border*/
input[type=range]:-moz-focusring{
    outline: 1px solid white;
    outline-offset: -1px;
}

input[type=range]::-ms-track {
    width: 80px;
    height: 2px;
    
    /*remove bg colour from the track, we'll use ms-fill-lower and ms-fill-upper instead */
    background: transparent;
    
    /*leave room for the larger thumb to overflow with a transparent border */
    border-color: transparent;
    border-width: 6px 0;

    /*remove default tick marks*/
    color: transparent;
}
input[type=range]::-ms-fill-lower {
    background: #777;
    border-radius: 10px;
}
input[type=range]::-ms-fill-upper {
    background: #61b4f7;
    border-radius: 10px;
}
input[type=range]::-ms-thumb {
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
}
input[type=range]:focus::-ms-fill-lower {
    background: #888;
}
input[type=range]:focus::-ms-fill-upper {
    background: #ccc;
}

<div class="slider-wrapper">
  <input type="range" orient="vertical" class="volume-slider"/>
</div>

Answer 1

为范围元素添加内边距会增加可点击空间。然后，您可以在元素上放置透明背景：

.slider-wrapper{
  background: rgba(0, 0, 0, 0.8);
  width: 40px;
  height: 100px;
  position: relative;
  left: 1px;
}

input[type=range] {
    padding: 19px 10px;
    background-color: transparent;

    /*removes default webkit styles*/
    -webkit-appearance: none;

    /*fix for FF unable to apply focus style bug */
    /*border: 1px solid white;*/

    /*required for proper track sizing in FF*/
    width: 80px;

    transform: rotate(270deg);

    position: relative;
    left: -32px;
    top: 28px;
}
input[type=range]::-webkit-slider-runnable-track {
    width: 80px;
    height: 2px;
    background: #61b4f7;
    border: none;
    /*border-radius: 2px;*/
}

input[type=range]::-webkit-slider-thumb {
    -webkit-appearance: none;
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
    margin-top: -4px;
}

input[type=range]:focus {
    outline: none;
}

input[type=range]:focus::-webkit-slider-runnable-track {
    background: #ccc;
}

input[type=range]::-moz-range-track {
    width: 80px;
    height: 2px;
    background: #61b4f7;
    border: none;
    /* border-radius: 3px; */
}
input[type=range]::-moz-range-thumb {
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
}

/*hide the outline behind the border*/
input[type=range]:-moz-focusring{
    outline: 1px solid white;
    outline-offset: -1px;
}

input[type=range]::-ms-track {
    width: 80px;
    height: 2px;
    
    /*remove bg colour from the track, we'll use ms-fill-lower and ms-fill-upper instead */
    background: transparent;
    
    /*leave room for the larger thumb to overflow with a transparent border */
    border-color: transparent;
    border-width: 6px 0;

    /*remove default tick marks*/
    color: transparent;
}
input[type=range]::-ms-fill-lower {
    background: #777;
    border-radius: 10px;
}
input[type=range]::-ms-fill-upper {
    background: #61b4f7;
    border-radius: 10px;
}
input[type=range]::-ms-thumb {
    border: none;
    height: 10px;
    width: 10px;
    border-radius: 50%;
    background: #61b4f7;
}
input[type=range]:focus::-ms-fill-lower {
    background: #888;
}
input[type=range]:focus::-ms-fill-upper {
    background: #ccc;
}

<div class="slider-wrapper">
  <input type="range" orient="vertical" class="volume-slider"/>
</div>
