使用HTML和CSS创建玻璃质感登录表单


本文将向您展示如何使用HTML和CSS设计一个玻璃质感登录表单。玻璃质感是一种流行的UI设计趋势,它基于磨砂玻璃效果,使元素看起来半透明,并带有模糊的背景。

在本文中,我们将使用HTML和CSS创建一个玻璃质感登录表单。

什么是玻璃质感?

玻璃质感是一种UI设计风格,它使元素具有磨砂玻璃效果。

  • 模糊背景:创建玻璃状的磨砂效果。
  • 透明度:允许部分背景显示。
  • 浅色边框和阴影:增加深度并定义形状。

在本文中,我们将了解如何使用HTML和CSS创建一个玻璃质感登录表单。

使用HTML和CSS创建玻璃质感登录表单

我们将遵循三个步骤。

创建HTML结构

我们首先构建登录表单的结构。我们使用单个容器来容纳用户名和密码输入字段以及提交按钮。

<!DOCTYPE html>
<html lang="en">

<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Glassmorphism Login Form</title>
    <link rel="stylesheet" href="styles.css">
</head>

<body>
    <div class="glass-container">
        <h2>Login</h2>
        <form>
            <input type="text" class="input-field" placeholder="Username" required>
            <input type="password" class="input-field" placeholder="Password" required>
            <button type="submit" class="btn">Login</button>
        </form>
    </div>
</body>

</html>

解释

  • 容器包含表单并将其居中于页面。
  • `glass-form` 类为表单提供了特定的类来应用玻璃质感样式。
  • 在表单内,我们有一个标题(h2)、两个输入字段(用于用户名和密码)和一个提交按钮。

解释

这里我们只解释了关键的CSS属性。

  • 背景动画:::before伪元素在玻璃容器后面创建平滑的渐变动画,增加了动态视觉效果。
  • 背景滤镜:backdrop-filter: blur(15px) 属性将磨砂玻璃模糊效果应用于容器。
  • 透明度 (RGBA):我们使用rgba(255, 255, 255, 0.1)作为背景颜色,它结合了透明度和白色,营造出玻璃状的半透明外观。
  • 输入字段焦点效果:当用户点击输入字段时,轻微的缩放和阴影效果增强了交互性,使用了transform: scale(1.02) 和 box-shadow。
  • 按钮悬停辉光:登录按钮在悬停时使用渐变和阴影效果,创建柔和的光晕以吸引注意力。
