这个动画步骤进度条的css制作的非常简单。那里有两个按钮可以控制步骤,它们将逐步进行。我在这个多步骤进度条 css 中使用了 4 个步骤。如果你愿意,你可以使用更多。
我使用了一些 javascript 来创建这一步进度条。横步进度条主要用在注册表中。以下是在 HTML 中创建步骤栏的步骤:
1234
@import url("https://fonts.googleapis.com/css2?family=Muli&display=swap");:root {--line-border-fill: #3498db;--line-border-empty: #e0e0e0;
}* {box-sizing: border-box;
}body {font-family: "Muli", sans-serif;background-color: #f6f7fb;display: flex;align-items: center;justify-content: center;height: 100vh;overflow: hidden;margin: 0;
}.container {text-align: center;
}.progress-container {display: flex;justify-content: space-between;position: relative;margin-bottom: 30px;max-width: 100%;width: 350px;
}.progress-container::before {content: ""; /* Mandatory with ::before */background-color: var(--line-border-empty);position: absolute;top: 50%;left: 0;transform: translateY(-50%);height: 4px;width: 100%;z-index: -1;
}.progress {background-color: var(--line-border-fill);position: absolute;top: 50%;left: 0;transform: translateY(-50%);height: 4px;width: 0%;z-index: -1;transition: 0.4s ease;
}.circle {background-color: #fff;color: #999;border-radius: 50%;height: 30px;width: 30px;display: flex;align-items: center;justify-content: center;border: 3px solid var(--line-border-empty);transition: 0.4s ease;
}.circle.active {border-color: var(--line-border-fill);
}.btn {background-color: var(--line-border-fill);color: #fff;border: 0;border-radius: 6px;cursor: pointer;font-family: inherit;padding: 8px 30px;margin: 5px;font-size: 14px;
}.btn:active {transform: scale(0.98);
}.btn:focus {outline: 0;
}.btn:disabled {background-color: var(--line-border-empty);cursor: not-allowed;
}
const progress = document.getElementById("progress");
const prev = document.getElementById("prev");
const next = document.getElementById("next");
const circles = document.querySelectorAll(".circle");let currentActive = 1;next.addEventListener("click", () => {currentActive++;if (currentActive > circles.length) currentActive = circles.length;update();
});prev.addEventListener("click", () => {currentActive--;if (currentActive < 1) currentActive = 1;update();
});const update = () => {circles.forEach((circle, index) => {if (index < currentActive) circle.classList.add("active");else circle.classList.remove("active");});const actives = document.querySelectorAll(".active");progress.style.width =((actives.length - 1) / (circles.length - 1)) * 100 + "%";if (currentActive === 1) prev.disabled = true;else if (currentActive === circles.length) next.disabled = true;else {prev.disabled = false;next.disabled = false;}
};
这将创建一个带有进度条和圆圈元素的基本步骤条来表示每个步骤。上一个和下一个按钮可用于在步骤之间导航,步骤栏的外观将根据当前活动步骤动态更新。
在这个例子中,步骤进度条由一个进度条和一系列用文本表示的步骤组成。进度条将根据当前活动的步骤改变宽度,步骤的外观将根据它们是否处于活动状态而改变。您可以根据需要调整宽度、颜色和字体大小值,以自定义步骤进度条的外观。
