Is a block behaving like an inline block element?

I'm currently working on a project and facing an issue with my dropdown navbar. Even though I have defined the elements as block-level in my CSS, they are displaying inline when hovering over the navbar items.

Below is a snippet of my code:

body {
  background-color: #555;
}

.navbar {
  width: 100%;
  height: 70px;
  background-color: #000000;
}

.logo {
  float: left;
  padding: 15px;
}

.navbar ul {
  margin: 0;
  padding: 0;
  float: left;
  list-style-type: none;
}

.navbar ul li {
  float: left;
}

...

<nav class="navbar">
  <div class="logo">
    <a href="~/Views/Home/Index.cshtml">
      <img src="~/Content/Pictures/CuttingEdgeWhite.png" style=" width: 200px; height: 50px;" />
    </a>
  </div>
  <ul>
    <li>
      <a href="#" class="nav-item">Electrical</a>
      <div class="nav-content">
        <div class="nav-sub">
          <ul>
            <li><a href="#">Option #1</a></li>
            ...

I've discovered that using float left for parent elements can cause issues with inline-block elements. I'm seeking advice on how to tackle this problem effectively. Any suggestions would be highly appreciated!

Answer №1

Fixing the Float Issue

If you're facing a float problem in your CSS, the quickest solution is to implement a simple change:

.navbar > ul > li {
  float: left;
}

The original rule was affecting the dropdown list as well. By adjusting it to target specific elements, you can resolve this issue.

Using Flexbox for a Cleaner Solution

  • To avoid using floats and achieve a cleaner layout, apply display: flex to both ul lists.
  • Remove all instances of the float property from your elements.
  • For the drop-down ul list, set flex-direction: column to display its items vertically.

Here's an example showcasing the implementation of these changes:

body {
  background-color: silver;
}

.navbar {
  width: 100%;
  height: 70px;
  background-color: #000000;
}

.logo {
  padding: 15px;
}

.navbar ul {
  margin: 0;
  padding: 0;
  list-style-type: none;
  display: flex;
}

.nav-item {
  display: block;
  padding: 15px 40px;
  height: 68px;
  line-height: 40px;
  color: white;
  text-decoration: none;
}

.nav-item:hover {
  background-color: darkred;
  color: white;
  text-decoration: none;
}

.nav-item:focus {
  background-color: darkred;
  color: white;
  text-decoration: none;
}

.nav-sub {
  background-color: #000000;
  display: none;
  position: absolute;
  min-width: 160px;
  box-shadow: 0px 8px 16px 0px rgba(0, 0, 0, 0.2);
  z-index: 1;
}

.nav-sub ul {
  flex-direction: column;
}

.nav-sub a {
  color: white;
  padding: 12px 16px;
  text-decoration: none;
  display: block;
  text-align: left;
}

.nav-sub a:hover {
  background-color: darkred;
}

.navbar ul li:hover .nav-sub {
  display: block;
}
<nav class="navbar">
  <div class="logo">
    <a href="~/Views/Home/Index.cshtml">
      <img src="~/Content/Pictures/CuttingEdgeWhite.png" style=" width: 200px; height: 50px;" />
    </a>
  </div>
  <ul>
    <li>
      <a href="#" class="nav-item">Electrical</a>
      <div class="nav-content">
        <div class="nav-sub">
          <ul>
            <li><a href="#">Option #1</a></li>
            <li><a href="#">Option #2</a></li>
            <li><a href="#">Option #3</a></li>
          </ul>
        </div>
      </div>
    </li>
    <li>
      <a href="#" class="nav-item">Lighting</a>
      <div class="nav-content">
        <div class="nav-sub">
          <ul>
            <li><a href="#">Option #1</a></li>
            <li><a href="#">Option #2</a></li>
            <li><a href="#">Option #3</a></li>
          </ul>
        </div>
      </div>
    </li>

Answer №2

Instead of behaving as inline blocks, they're functioning as floating elements… due to the fact that you've floated them.

.menu ul li {
  float: left;
}

If you desire a vertical arrangement, avoid floating them.

.menu > ul > li {
  float: left;
}
