所以我做了一个ejs登录项目style.css:

[theme="bloodRed"] {
    background-color: #ff2424;
    color: #e571e1;
    accent-color: #00ff00;
}

register.ejs:

<!DOCTYPE html>
<html lang="en" theme="bloodRed">
    <head>
        <meta charset="UTF-8">
        <meta http-equiv="X-UA-Compatible" content="IE=edge">
        <meta name="viewport" content="width=device-width, initial-scale=1">
        <title>Sign up</title>
        <link href="https://cdn.jsdelivr.net/npm/bootstrap@5.3.0-alpha1/dist/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-GLhlTQ8iRABdZLl6O3oVMWSktQOp6b7In1Zl3/Jr59b6EGGoI1aFkw7cmDA6j6gD" crossorigin="anonymous">
        <link href="/css/style.css" rel="stylesheet">
        <link rel="icon" href="https://getbootstrap.com/docs/5.3/assets/img/favicons/favicon-32x32.png" sizes="32x32" type="image/png">
    </head>
    <body>
        <div class="container">
            <div class="login-box">
                <div class="row">
                    <div class="col-md-6">
                        <h2>Sign up</h2>
                        <form action="register" method="post">
                            <div class="form-group">
                                <label>First and Last name</label>
                                <input type="text" name="name" class="form-control" required>
                            </div>
                            <div class="form-group">
                                <label>Email</label>
                                <input type="email" name="email" class="form-control" required>
                            </div>
                            <div class="form-group">
                                <label>Password</label>
                                <input type="password" name="password" class="form-control" required>
                            </div>
                            <button type="submit" class="btn btn-outline-info" style="margin-top: 10px;"> Sign up </button>
                        </form>
                        <p style="margin-top: 15px;">Already have an account?   <a class="btn btn-outline-success" href="login">Login here!</a></p>
                    </div>
                </div>
            </div>
        </div>
    </body>
</html>

然后这个js代码连接它们:

const express = require("express");
const app = express();
app.use(express.static("public"));
app.set("view engine", "ejs");

但是在register.ejs中,文本和背景都没有改变,如果你离开div,它是红色的,有帮助吗?

CSS遵循特异性和级联规则。您正在将theme属性添加到html元素中,但是Bootstrap CSS(在重新启动时)覆盖了它,因为它在正文上应用了白色的背景色和#212529;的文本color
将主题属性添加到body标记中会有所帮助,但还有很多其他地方会应用文本或背景色。最好使用Bootstrap SASS模块和/或自定义属性(CSS变量)。Customization的文档部分详细说明了如何使用。
