Question

The common CSS technique using the before pseudo class is failing to address the issue of content disappearing behind the page

I've been struggling with implementing CSS code in my main stylesheet file. I followed the advice online to use the ::before pseudo class to align the height and margin with the header. However, even after making these adjustments, the content still appears behind the header when I click on a link leading to the corresponding section with the correct ID. This issue has been quite frustrating for me, and I would appreciate any help or suggestions to resolve it.

header {
    // CSS code for header styling
}
content {
    // CSS code for content styling
}
section {
    // CSS code for section styling
}
    section::before {
        // CSS code for section before styling
    }
section-content {
    // CSS code for section content styling
}
footer {
    // CSS code for footer styling
}

HTML

<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
<head>
    // Meta tags, links to stylesheets, and scripts
</head>
<body>
    // Content structure including header, ticker, social media links, particles, intro, content sections, and footer
</body>
</html>

Answer №1

While I haven't explored the use of ::before to address this problem, an alternative approach could involve adjusting the height and utilizing negative margins.

In analyzing your scenario, it appears that the issue may stem from using the actual "title" element as the anchor element. To resolve this, I recommend designating a separate (invisible) element as your anchor to prevent any disruption to the regular layout of your webpage. This way, you can customize the styling of your "title" element as needed:

/* key styles */
#demo {
  padding-top: 50px;
}

header {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 50px;
  z-index: 2;
}

.section-anchor {
  margin-top: -50px;
  height: 50px;
  display: block;
  visibility: hidden;
}

/* demo-specific styles */
* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
}
header {
  background: rgba(0, 0, 0, 0.3);
  padding: 10px;
}
header a {
  color: #fff;
}
.section {
  position: relative;
  z-index: 1;
}
.title {
  padding: 10px;
  font-size: larger;
  font-weight: bold;
  background: rgba(200,0,0,0.3);
  background-image: repeating-linear-gradient(-45deg, #dff, #dff 10px, #eee 10px, #eee 20px);
  opacity: 0.5;
}
p {
  height: 500px;
  border: 10px solid #bbb;
  background-image: repeating-linear-gradient(45deg, #ddd, #ddd 30px, #eee 30px, #eee 60px);
  opacity: 0.3;
}

<div id="demo">
<header>
  <a href="#section1">Section 1</a>
  <a href="#section2">Section 2</a>
  <a href="#section3">Section 3</a>
</header>
<div class="section">
  <a class="section-anchor" name="section1"></a>
  <div class="title">Section 1</div>
  <p>Text...</p>
</div>
<div class="section">
  <a class="section-anchor" name="section2">-</a>
  <div class="title">Section 2</div>
  <p>Text...</p>
</div>
<div class="section">
  <a class="section-anchor" name="section3"></a>
  <div class="title">Section 3</div>
  <p>Text...</p>
</div>
</div>

Answer №3

To enhance the layout, consider enclosing all content beneath the header within a designated main section and adjusting its position slightly lower on the page.

Use the following CSS for guidance:

main {
  top: 2em; /* Adjust as needed */
  }

The issue at hand: By setting the header's position as fixed, it is removed from the natural flow of elements causing everything outside the header to occupy the page normally, while the header remains on top. To counteract this, offset the rest of the content further down the page.
