火狐瀏覽器輸入問題。怎么修？

默認情況下，Firefox 中的滑塊看起來是灰色的。據我了解，Firefox 不接受很多 css 標簽，input[type=range]::-webkit-slider-thumb例如，我嘗試moz-range-thumb在現有的 CSS 中添加標簽，就像我設法做到了一樣，但滑塊的背景仍然是白色的，這僅在 Firefox 中。

變化后的樣子：

我的CSS代碼：

input[type=range] {
    -webkit-appearance: none;
    width: 100%;
}

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

input[type=range]:focus::-webkit-slider-runnable-track {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]:focus::-ms-fill-lower {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]:focus::-ms-fill-upper {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]::-webkit-slider-runnable-track {
    width: 100%;
    height: 5px;
    cursor: pointer;
    animate: 0.2s;
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
    border-radius: 1px;
    box-shadow: none;
    border: 0;
}

input[type=range]::-webkit-slider-thumb {
    z-index: 2;
    position: relative;
    box-shadow: 0px 0px 0px #000;
    border: 1px solid #2497e3;
    height: 18px;
    width: 18px;
    border-radius: 25px;
    background: #a1d0ff;
    cursor: pointer;
    -webkit-appearance: none;
    margin-top: -7px;
}

input[type=range]::-moz-range-thumb {
    z-index: 2;
    position: relative;
    box-shadow: 0px 0px 0px #000;
    border: 1px solid #2497e3;
    height: 18px;
    width: 18px;
    border-radius: 25px;
    background: #a1d0ff;
    cursor: pointer;
    -webkit-appearance: none;
    margin-top: -7px;
}

input[type=range]::-moz-range-track {
    width: 100%;
    height: 5px;
    cursor: pointer;
    animate: 0.2s;
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
    border-radius: 1px;
    box-shadow: none;
    border: 0;
}

input[type=range]:-moz-focusring {
    outline: none;
}

input[type=range]:focus::-moz-range-track {
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
}

如何在 Firefox 瀏覽器中洗掉此白色背景？

uj5u.com熱心網友回復：

除了添加backgroundfor input[type=range]。你可以設定height = 0為input[type=range].

body{
  background:gray;
}
input[type=range] {
    -webkit-appearance: none;
    width: 100%;
    height:0;
    /* background:none; */
}

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

input[type=range]:focus::-webkit-slider-runnable-track {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]:focus::-ms-fill-lower {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]:focus::-ms-fill-upper {
    background: linear-gradient(
    90deg
    ,#29bddd,#923ddd),#c4c4c4;
}

input[type=range]::-webkit-slider-runnable-track {
    width: 100%;
    height: 5px;
    cursor: pointer;
    animate: 0.2s;
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
    border-radius: 1px;
    box-shadow: none;
    border: 0;
}

input[type=range]::-webkit-slider-thumb {
    z-index: 2;
    position: relative;
    box-shadow: 0px 0px 0px #000;
    border: 1px solid #2497e3;
    height: 18px;
    width: 18px;
    border-radius: 25px;
    background: #a1d0ff;
    cursor: pointer;
    -webkit-appearance: none;
    margin-top: -7px;
}

input[type=range]::-moz-range-thumb {
    z-index: 2;
    position: relative;
    box-shadow: 0px 0px 0px #000;
    border: 1px solid #2497e3;
    height: 18px;
    width: 18px;
    border-radius: 25px;
    background: #a1d0ff;
    cursor: pointer;
    -webkit-appearance: none;
    margin-top: -7px;
}

input[type=range]::-moz-range-track {
    width: 100%;
    height: 5px;
    cursor: pointer;
    animate: 0.2s;
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
    border-radius: 1px;
    box-shadow: none;
    border: 0;
}

input[type=range]:-moz-focusring {
    outline: none;
}

input[type=range]:focus::-moz-range-track {
    background: linear-gradient(
            90deg
            ,#29bddd,#923ddd),#c4c4c4;
}

<input type="range">

uj5u.com熱心網友回復：

你應該只設定backgroundfor input[type=range]。

這是一個簡化的示例：

input[type=range] {
    -webkit-appearance: none;
    width: 500px;
    height: 20px;
    background: pink;
}
/* Firefox */
input[type=range]::-moz-range-thumb {
    background: blue;
}
input[type=range]::-moz-range-track {
    background: purple;
}
/* Chrome */
input[type=range]::-webkit-slider-thumb {
    background: blue;
    margin-top: -5px;
}
input[type=range]::-webkit-slider-runnable-track {
    background: purple;
    height: 5px;
}

<input type="range"  />
