    <p id="about">My name is Lawrence Yoon and I graduated from Cal Poly Pomona with a degree in Hospitality Management and minor in Business Marketing. After working in the hospitality industry for 5+ years, I wanted to expand my knowledge by trying out different
      career paths and happened to find out about computer programming. I've been self-learning for 3+ months, and hope to become a front-end web developer soon! I am proficient with HTML and CSS, and have some knowledge of JavaScript. Once I get my first
      job, I hope to continue studying and eventually learn back-end. My goal is to one day become a full-stack developer!</p>
    <p>So far, I have knowledge of HTML, CSS, Bootstrap, JavaScript, and jQuery. I have used StackOverflow a couple times, and although I don't rely on this, it's great to ask questions and receive answers promptly from a loving community. Jon Duckett's
      Introduction to HTML and CSS has been a great teacher to me thus far; although it's a bit dated, it contains detailed images and helped me greatly step foot into the world of web development. Following this book, I got his second book for JavaScript
      and jQuery and have started to read through that. While I'm doing this, I'm learning from FreeCodeCamp, which immensely helped because through their projects, I'm able to make this file on Codepen, which will become my portfolio! I will definitely
      try to finish all FCC challenges, and make a couple of apps to showcase my skills!</p>
    <p>As of right now, I'm not looking for a job because I lack the skills necessary to get my first job in web development. In a couple of months, I hope to polish what I know so far as well as learn new skills to get my first job. In time, I will showcase
      my skills by demonstrating my abilities through the makings of small apps. Thanks for reading! Please don't hesitate to reach out to me to provide tips, or if you want to talk about anything I'm all ears!</p>

两个问题：

我的position: fixed导航栏阻挡了我的锚标签（关于，投资组合，联系人），这意味着当我点击它们时，它会将我带到他们的位置，但导航栏会阻塞开始。当我点击顶部的链接时，如何才能让它从我的导航栏下面开始？
我正在使用CSS li:visited {text-decoration: none;}，但它会变为紫色，但仍有下划线。为什么会这样？

Answer 1

要解决页内锚点和固定标题的问题，您需要做的是在内容部分上创建并相对定位一个锚元素。

小提琴示例：https://jsbin.com/dosalajotu/edit?html,css,output

例如，如果标题为50px高：

header { height: 50px; }
.anchor { position: relative; top: -50px; }

<section>
    <div id="about" class="anchor"></div>
</section>

对于:visited州，这适用于a元素，而不适用于li元素。如果您更新CSS选择器并覆盖颜色，那么应解决问题。

li a:active, li a:visited { color: red; text-decoration: none; }

位置：固定的锚定方式？
