是否可以在不使用 JavaScript 的情况下在选择更改时为单选按钮设置动画？

Question

我正在通过使用样式丰富的单选按钮为应用程序制作一个选择栏，这样我可以确保一次只能选择一个元素，并且还使用方便的样式技巧，因此我必须减少编码。然而，现在我正在尝试为它们设置动画，每当选定的按钮发生变化时，都会稍微放松一下。每当选择一个元素时，我都会更改背景颜色，并且希望它沿线线性移动它，直到到达应具有背景颜色的元素的新位置。仅使用 CSS 和 HTML 可以实现这一点吗？或者我需要添加一些 JavaScript 才能使其工作吗？如果是，具体如何？

我尝试了很多事情，比如在不同的地方添加背景颜色，我尝试了不同的动画方式，但没有任何效果是我喜欢的。我设法获得了一个动画，当我切换按钮时，

form

会折叠，因此在输入更改时触发动画并非不可能。

这是我的代码（我试图让它稍微更通用，这样其他人也可以从中受益:)

<script lang="ts">
    import './example.css';

    export let options: "OPTION1" | "OPTION2" | "OPTION3" = "OPTION1";

    const handleClick = () => {
        const option1 = document.getElementById('option1') as HTMLInputElement;
        const shortBreak = document.getElementById('option2') as HTMLInputElement;
        const longBreak = document.getElementById('option3') as HTMLInputElement;

        if (option1.checked) {
            options = "OPTION1";
        } else if (option2.checked) {
            options = "OPTION2";
        } else if (option3.checked) {
            timerType = "OPTION3";
        }

        console.log(`debug> option selected: ${options}`);
    }
</script>

<div class="options">
    <form>
        <label>
            <input type="radio" id="option1" name="options" checked on:click={handleClick}>
            <span>Option 1</span>
        </label>
        <label>
            <input type="radio" id="option2" name="options" on:click={handleClick}>
            <span>Option 2</span>
        </label>
        <label>
            <input type="radio" id="option3" name="options" on:click={handleClick}>
            <span>Option 3</span>
        </label>
    </form>
</div>

input[type="radio"] {
    display: none;
}

form {
    display: flex;
    align-items: center;
    justify-content: space-between;
    flex-wrap: nowrap;
    overflow: hidden;
    background-color: #242424;
    color: white; /* needed for debugging, otherwise you can't really visualize what happens */
    border-radius: 10px;
    padding-left: 5px;
    padding-right: 5px;
}

label {
    display: flex;
    align-items: center;
    cursor: pointer;
    max-width: 300px;
    white-space: nowrap;
    overflow: hidden; 
    text-overflow: ellipsis;
    border-radius: 10px;
    margin: 0; 
}

form > label:not(:first-child) {
    margin-left: 5px;
}

*, *::before, *::after {
    box-sizing: border-box;
}

input[type="radio"]:checked + span {
    background-color: #747bff;
    padding: 10px;
    border-radius: 10px;
    margin: 0;
}

label span {
    margin-left: 0;
}

PS。我遇到的其他事情是，如果我选择第一个元素，则

form

和

label

之间存在轻微间隙。如果你们也能帮助我，那就太好了。

这里有一篇文章可以帮助您制作单选按钮和复选框的动画 https://codepen.io/im_vikasdeep/pen/oNxwjZJ

您可以将复选框替换为单选框

* {
    box-shadow: none;
}

body {
    font-family: 'Poppins', sans-serif;
    margin: 0;
    width: 100%;

    display: flex;
    justify-content: center;
    align-items: center;
    font-size: 17px;
}

.container {
    max-width: 1000px;
    width: 100%;
    display: flex;
    flex-wrap: wrap;
    justify-content: space-around;
}

.switch-holder {
    display: flex;
    padding: 10px 20px;
    border-radius: 10px;
    margin-bottom: 30px;
