我从头开始构建了终极教育网站 — 第 3 天

很多人问我，要花多少时间在这上面。我想可能需要两到三周。但是，这个问题让我重新思考我在网站上花费了多少时间。我光是主页就花了8个小时。因此，我决定快速创建内容，而不是像前几天那样关注微小的细节。我已经浪费了你们很多注意力，现在让我们直接进入流程。

第 19 小时：创建化学内容页面

我将首先在 Chemistry/3/ 目录中创建 periodicality-of-elements-qa.html 文件。此页面将包含有关元素周期性主题的问题和解答。

    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Periodicity of Elements - Questions and Answers</title>
        <!-- styles and scripts -->


    <header>
        <nav>
            <div>



<p>As usual, I included a basic HTML boilerplate with links to necessary scripts and styles, along with navigation to main pages. I am using a container div, aside element with the id table-of-contents, which will be populated using javascript, and finally the main tag.</p>

<p>Next, I added the content, formatted with heading tags and some paragraph tags for the main body. For formulas and symbols I used the LaTeX syntax, LaTeX is used because it is the go-to standard:<br>
</p>

<pre class="brush:php;toolbar:false">            <h2>



</h2><p>This contains a lot of content, which is formatted using headings and sub-headings, some lists and tables. I also added an "About the Author" tag for authenticity.</p>

<p>I needed to style this page so that the text can be readable, and it doesn't look too bad. I will add an additional css file into this page, keeping style.css and style-main.css for common elements.</p>

<h2>
  
  
  Hour 20: Styling the content page and adding JS for dynamic Table of Contents
</h2>

<p>I created an style tag inside the head element, and added basic style to it:<br>
</p>

<pre class="brush:php;toolbar:false">     <style>

    position: relative; /* For the underline effect */
    padding-bottom: 4px; /* Space for the underline */
    transition: color 0.3s ease-in-out, transform 0.3s ease-in-out;

    transform: scaleX(0); /* Initially hidden */
    transform-origin: bottom right;
    transition: transform 0.4s ease-out;
}

nav ul li a:hover {
    color: #90caf9; /* Lighter hover color */
    transform: translateY(-2px); /* Slight lift on hover */
}

nav ul li a:hover::before {
    transform: scaleX(1);
    transform-origin: bottom left;

    }
}
    </style>

这只是基本样式，对标题和主要内容进行了一些更改，以确保元素可读，不会太分散注意力，并且在整个网站上保持一致。
我还为表格、块引用和代码块添加了 CSS，以提高可读性。

我还想添加一个脚本来使左侧的目录具有交互性。因此，我将此脚本添加到 body 标记的底部：

<script>
        // script.js
document.addEventListener('DOMContentLoaded', () => {
    const mainContent = document.querySelector('main');
    const tableOfContents = document.getElementById('table-of-contents');

    if (!mainContent || !tableOfContents) {
        console.error('Main content or table of contents element not found.');
        return;
    }

    const headings = mainContent.querySelectorAll('h2, h3, h4');
    const tocList = document.createElement('ul');

    let currentList = tocList;
    const stack = [currentList];

    headings.forEach(heading => {
        const tagName = heading.tagName;
        const id = heading.id;
        const text = heading.textContent;

        if (id) {
            const listItem = document.createElement('li');
            const link = document.createElement('a');
            link.href = `#${id}`;
            link.textContent = text;
            listItem.appendChild(link);

            if (tagName === 'H2') {
                while (stack.length > 1) {
                    stack.pop();
                }
                currentList = stack[stack.length - 1];
                currentList.appendChild(listItem);
                stack.push(document.createElement('ul'));
                currentList = stack[stack.length - 1];
                listItem.appendChild(currentList);
            } else if (tagName === 'H3') {
                while (stack.length > 2) {
                    stack.pop();
                }
                currentList = stack[stack.length - 1];
                currentList.appendChild(listItem);
                stack.push(document.createElement('ul'));
                currentList = stack[stack.length - 1];
                listItem.appendChild(currentList);
            } else if (tagName === 'H4') {
                while (stack.length > 3) {
                    stack.pop();
                }
                currentList = stack[stack.length - 1];
                currentList.appendChild(listItem);
            }
        }
    });

    // Remove any empty ul elements that might have been created
    function removeEmptyLists(list) {
        Array.from(list.children).forEach(item => {
            if (item.tagName === 'UL' && item.children.length === 0) {
                item.remove();
            } else if (item.tagName === 'LI') {
                const childUl = item.querySelector('ul');
                if (childUl) {
                    removeEmptyLists(childUl);
                }
            }
        });
    }
    removeEmptyLists(tocList);

    const tocTitle = document.createElement('h2');
    tocTitle.textContent = 'Table of Contents';
    tableOfContents.appendChild(tocTitle);
    tableOfContents.appendChild(tocList);
});
    </script>

此脚本会自动从主元素中的标题生成嵌套目录，该目录可以无缝运行。该脚本会自动填充我之前创建的目录旁标记。

最后，我通过在 head 标签内添加这些脚本和链接标签来添加对 LaTeX 公式和方程的支持。

        <link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.css">
        <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/katex.min.js"></script>
        <script defer src="https://cdn.jsdelivr.net/npm/katex@0.16.4/dist/contrib/auto-render.min.js"></script>
        <script>
            document.addEventListener("DOMContentLoaded", function () {
                renderMathInElement(document.body, {
                    delimiters: [
                        { left: "$", right: "$", display: false },
                        { left: "$$", right: "$$", display: true }
                    ]
                });
            });
        </script>

这样，内容页面就完成了。我喜欢它的设计非常简约，不会分散对内容的注意力，并且仍然具有所有必要的功能。
如果您想了解实际版本的情况，而不仅仅是自己复制内容，请参阅此处：元素的周期性 - 问题与解答

第 21 至 25 小时：完成化学内容页

我将在 Chemistry/3/ 文件夹中创建 periodicality-of-elements-notes.html 文件。这将包含有关元素周期性的注释。

<p>This is the same base HTML structure as the previous file, periodicity-of-elements-qa.html. </p>

然后，我像以前一样添加了目录的 JavaScript，并添加了一个脚本来生成元素属性表：

        让calculateBtn = document.getElementById('calculate-btn');

<p>我为计算器添加了很多内容，以及动态生成目录的逻辑，以及计算每个元素的值的逻辑。诺亚问我是否可以集成基本计算器，计算元素及其共价半径和键长。页面现已准备就绪！想看的话就在这里：<br>
元素的周期性 - 注释</p>

<p>这标志着一天的编码结束。我知道，感觉有点仓促，因为确实如此。我无法准确描述我做了什么以及为什么，因为我也不记得其中的大部分内容。我只记得基本的变化。</p>
