在已居中的容器上方制作文本框

Question

我正在尝试制作一个内容丰富的文本框，我觉得答案应该非常简单，但我忽略了一些东西。经过几次尝试并检查了强大的 GPT，我来这里寻求建议。

目前看起来像这样

我希望它看起来像这样，其中标记的区域是文本框

代码如下

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Password Strength Checker</title>
    <link rel="stylesheet" href="styles.scss">
</head>
<body>
    <!-- Informative Text Box Container -->
    <div class="info-container">
        <p>This is an informative text box. It provides guidelines for creating a strong password.</p>
</div>

<!-- Main Content Container -->
<div class="container">
    <h1>Password Strength Checker</h1>
    <label for="password">Enter Password:</label>
    <input type="password" id="password" placeholder="Password">
    <div class="criteria">
        <div class="criteria-item" id="capitalCheck">Capital Letters: <span class="indicator"></span></div>
        <div class="criteria-item" id="numberCheck">Numbers: <span class="indicator"></span></div>
        <div class="criteria-item" id="symbolCheck">Symbols: <span class="indicator"></span></div>
    </div>
    <button onclick="calculateTime()">Calculate</button>
    <div id="result"></div>
</div>

<script src="script.js"></script>

还有 scss

/* styles.scss */

/* Informative Text Box Container */
.info-container {
    background-color: #f0f0f0;
    padding: 20px;
    margin-bottom: 20px;
    border: 1px solid #ccc;
    border-radius: 5px;
    text-align: center; /* Center text */
}

/* Main Content Container */
.container {
    background-color: #fff;
    padding: 30px; /* Adjusted padding to match the informative text box */
    width: 400px; /* Matched width with .article.container */
    border-radius: 5px;
    box-shadow: 0 2px 5px rgba(0, 0, 0, 0.1);
}

/* Additional styles */
.criteria-item {
    margin-bottom: 10px;
}

/* Rest of your existing styles */
body {
    font-family: Arial, sans-serif;
    background-color: #f5f5f5;
    margin: 0;
    padding: 0;
    display: flex;
    justify-content: center;
    align-items: center;
    height: 100vh;
}

.container>h1 {
    font-size: 24px;
    text-align: center;
    margin-bottom: 20px;
}

label {
    font-size: 16px;
    display: block;
    margin-bottom: 10px;
}

input[type="password"] {
    width: 100%;
    padding: 10px;
    margin-bottom: 20px;
    border: 1px solid #ccc;
    border-radius: 3px;
}

button {
    padding: 10px 20px;
    background-color: #007bff;
    color: #fff;
    border: none;
    border-radius: 3px;
    cursor: pointer;
    font-size: 16px;
    transition: background-color 0.3s ease;
}

button:hover {
    background-color: #0056b3;
}

p#result {
    margin-top: 20px;
    font-size: 18px;
    text-align: center;
}

ul.criteria {
    display: flex;
    justify-content: space-between;
    margin-bottom: 20px;
}

ul.criteria>li {
    font-size: 16px;
}

span.indicator {
    font-size: 16px;
    color: red;
}

span.valid {
    color: green;
}

最后是 javascript

document.getElementById("password").addEventListener("input", function() {
    var password = this.value.trim(); // Trim to remove leading and trailing spaces
    var capitalCheck = document.getElementById("capitalCheck").querySelector(".indicator");
    var numberCheck = document.getElementById("numberCheck").querySelector(".indicator");
    var symbolCheck = document.getElementById("symbolCheck").querySelector(".indicator");

    capitalCheck.textContent = /[A-Z]/.test(password) ? '✔' : '✘';
    numberCheck.textContent = /\d/.test(password) ? '✔' : '✘';
    symbolCheck.textContent = /[!@#$%^&*()_+\-=[\]{};':"\\|,.<>/?]/.test(password) ? '✔' : '✘';

    capitalCheck.style.visibility = /[A-Z]/.test(password) ? "visible" : "visible";
    numberCheck.style.visibility = /\d/.test(password) ? "visible" : "visible";
    symbolCheck.style.visibility = /[!@#$%^&*()_+\-=[\]{};':"\\|,.<>/?]/.test(password) ? "visible" : "visible";
});


function calculateTime() {
    var password = document.getElementById("password").value;
    var charCount = password.length;
    var hasUpperCase = /[A-Z]/.test(password);
    var hasNumber = /\d/.test(password);
    var hasSymbol = /[!@#$%^&*()_+\-=[\]{};':"\\|,.<>/?]/.test(password);

    var possibleCharacters = 26 + (hasUpperCase ? 26 : 0) + (hasNumber ? 10 : 0) + (hasSymbol ? 32 : 0); // lowercase letters + uppercase letters + numbers + symbols
    var permutations = Math.pow(possibleCharacters, charCount);

    var seconds = permutations / 1000000000; // divide by 1 billion to convert to seconds
    var minutes = seconds / 60;
    var hours = minutes / 60;
    var days = hours / 24;
    var years = days / 365;

    var result = "It would take approximately ";
    if (years >= 1) {
        result += Math.floor(years) + " years, " + Math.floor(days % 365) + " days, " + Math.floor(hours % 24) + " hours, " + Math.floor(minutes % 60) + " minutes, and " + Math.floor(seconds % 60) + " seconds to crack this password.";
    } else if (days >= 1) {
        result += Math.floor(days) + " days, " + Math.floor(hours % 24) + " hours, " + Math.floor(minutes % 60) + " minutes, and " + Math.floor(seconds % 60) + " seconds to crack this password.";
    } else if (hours >= 1) {
        result += Math.floor(hours) + " hours, " + Math.floor(minutes % 60) + " minutes, and " + Math.floor(seconds % 60) + " seconds to crack this password.";
    } else if (minutes >= 1) {
        result += Math.floor(minutes) + " minutes, and " + Math.floor(seconds % 60) + " seconds to crack this password.";
    } else {
        result += Math.ceil(seconds) + " seconds to crack this password.";
    }

    document.getElementById("result").innerText = result;
}

Answer 1

只需将其添加到 scss 或 css （这是基于您的 html）

CSS 或 SCSS :

body {
   /** rest of the css **/
    display: flex;
    flex-direction: column;
    align-items: center;
    justify-content: flex-start;        
  }
