如何用HTML/CSS美观展示数据库中1-5个可变数据？

Hey there! I see your current layout is a bit messy with inline styles and generic elements—let's refactor it to be cleaner, more semantic, and responsive. Here's a better approach using semantic HTML, Flexbox for layout, and reusable CSS classes:

The Problem with Your Current Code #

Your inline styles make maintenance a headache, the rotated headers are misaligned, and using spans for list items isn't semantic. Plus, empty items would still show up, which isn't ideal for your variable 1-5 data points.

Solution: Semantic HTML + Flexbox Layout #

Step 1: HTML Structure (Semantic & Clean) #

We'll use semantic elements like <section> for the container, <h3> for headers, and <ul>/<li> for lists—this makes the markup more readable and accessible.

<section class="dual-list-container">
  <!-- Left List -->
  <div class="list-column">
    <h3 class="rotated-header">
      List1: {{ en.form.nbTotalCon }}
    </h3>
    <ul class="item-list">
      <li class="list-item">{{ en.form.part1 }}</li>
      <li class="list-item">{{ en.form.part2 }}</li>
      <li class="list-item">{{ en.form.part3 }}</li>
      <li class="list-item">{{ en.form.part4 }}</li>
      <li class="list-item">{{ en.form.part5 }}</li>
    </ul>
  </div>

  <!-- Right List -->
  <div class="list-column">
    <h3 class="rotated-header">
      Projects: {{ en.form.nbTotalProj }}
    </h3>
    <ul class="item-list">
      <li class="list-item">{{ en.form.nomProj1 }}</li>
      <li class="list-item">{{ en.form.nomProj2 }}</li>
      <li class="list-item">{{ en.form.nomProj3 }}</li>
      <li class="list-item">{{ en.form.nomProj4 }}</li>
      <li class="list-item">{{ en.form.nomProje5 }}</li>
    </ul>
  </div>
</section>

Step 2: CSS (Flexible & Responsive) #

We'll use Flexbox to align columns, properly position rotated headers, add alternating list item backgrounds, and automatically hide empty items.

/* Main container for both columns */
.dual-list-container {
  display: flex;
  gap: 2rem; /* Space between columns */
  margin: 5% auto;
  max-width: 1200px; /* Prevent over-stretching on wide screens */
  padding: 0 1rem;
}

/* Each column takes equal space */
.list-column {
  flex: 1;
  display: flex;
  align-items: flex-start;
  gap: 1.5rem;
}

/* Rotated header styling */
.rotated-header {
  background-color: gray;
  color: white;
  padding: 1rem;
  margin: 0;
  width: 50px; /* Fixed width after rotation */
  height: 175px;
  display: flex;
  align-items: center;
  justify-content: center;
  transform: rotate(-90deg);
  transform-origin: center center;
  text-align: center;
}

/* List base styling */
.item-list {
  list-style: none;
  padding: 0;
  margin: 0;
  flex: 1;
}

/* List items with alternating backgrounds */
.list-item {
  padding: 0.5rem 1rem;
  margin-bottom: 0.3rem;
}

.list-item:nth-child(odd) {
  background-color: darkgray;
}

/* Hide empty list items automatically */
.list-item:empty {
  display: none;
}

/* Responsive adjustment for mobile */
@media (max-width: 768px) {
  .dual-list-container {
    flex-direction: column;
  }
  
  .rotated-header {
    transform: rotate(0deg);
    width: auto;
    height: auto;
  }
  
  .list-column {
    flex-direction: column;
    align-items: flex-start;
  }
}

Key Improvements: #

• Semantic HTML: <ul>/<li> makes your list structure clear for browsers and other developers.
• Flexbox Alignment: Columns stay evenly spaced and aligned, even if content lengths differ.
• Automatic Empty Item Hiding: The :empty pseudo-class hides any list items without data—perfect for your 1-5 variable entries.
• Alternating Backgrounds: nth-child(odd) handles the stripe pattern automatically, no manual class additions needed.
• Responsive Design: Switches to a vertical stack on mobile with non-rotated headers for better usability.
• Maintainable CSS: Reusable classes mean you can tweak styles across the entire layout in one place.

This will give you a clean, professional layout that adapts to your variable data count and works well on all screen sizes!
