The header navigation bar remains fixed in place and does not shift upwards

I encountered an issue with my HTML and CSS code...everything was working smoothly until I decided to add a class name for the <ul> and <li>, like this:

<nav class="navContainer">

    <ul class="navbar">
        <li class="leftSide navItem active"><a class=" home " href="#Home"><i class="fas fa-home"></i><br><span>Home</span></a></li>
        <li class="leftSide navItem"><a class=" about scroll" href="#About"><i class="fas fa-id-card"></i><br><span>About Us</span></a></li>
        <li class="middle navItem"><a class=" service scroll" href="#Services"><i class="fas fa-bolt"></i><br><span>Our Services</span></a></li>
        <li class="middle navItem"><a class=" work scroll" href="#Work"><i class="fas fa-suitcase"></i><br><span>Our work</span></a></li>
        <li class="rightSide navItem"><a class=" products scroll" href="#Products"><i class="fas fa-solar-panel"></i><br><span>Our products</span></a></li>
        <li class="rightSide navItem"><a class=" contact scroll" href="#Contact"><i class="fas fa-headset"></i><br><span>Contact Us</span></a></li>

    </ul>
<nav>

This caused the navbar to appear vertically instead of horizontally. To rectify this, I had to adjust the selectors in the CSS code as follows:


/* header st */

.mainContainer header {
    position: fixed;
    top: 0;
    background-color: #45af0d;
    width: 100%;
    height: 256px;
}


/* navBar st */

.mainContainer header .navContainer {
    display: flex;
    justify-content: space-between;
    background-color: transparent;
    text-transform: uppercase;
    font-size: 1.25rem;
    font-weight: bolder;
}

.mainContainer header .navContainer ul.navbar {
    text-align: center;
    background-color: transparent;
    min-width: 696px;
    list-style: none;
}

...

The classes were named for a jQuery code that handles switching the active navbar during scrolling.

The final result after making these changes can be viewed here: https://i.sstatic.net/pyfkJ.png

The li elements were not displaying correctly.

I removed all relevant margin-top properties related to the header, except for the SVG. Despite this, the alignment issue persisted. Am I overlooking something?

Answer №1

When names of styles change and previous rules no longer apply, adjustments need to be made. Consider updating the rules from:

.mainContainer header .navContainer ul.navbar { ... }

.mainContainer header .navContainer ul.navbar li.navItem { ...}

to

nav.navContainer ul.navbar { ... }

nav.navContainer ul.navbar li.navItem { ... }

and make sure to set the max-height property to match the height of the header, which is 256px.

Here's an example:

/* styles for header */

.mainContainer header {
  position: fixed;
  top: 0;
  background-color: #45af0d;
  width: 100%;
  height: 256px;
}


/* styles for navbar */

.mainContainer header .navContainer {
  display: flex;
  justify-content: space-between;
  background-color: transparent;
  text-transform: uppercase;
  font-size: 1.25rem;
  font-weight: bolder;
}

nav.navContainer ul.navbar {
  text-align: center;
  background-color: transparent;
  min-width: 696px;
  max-height: 256px;
  list-style: none;
}

nav.navContainer ul.navbar li.navItem {
  background-color: transparent;
  display: inline-flex;
}

.mainContainer header .navContainer ul.navbar li.navItem a {
  text-decoration: none;
  color: #f1f2f6;
}

.mainContainer header .navContainer ul.navbar li.navItem {
  --border-color: #f1f1f1;
  --border-width: 5px;
  --bottom-distance: 0px;
  margin: 10px;
  margin-left: 90px;
  background-image: linear-gradient(var(--border-color), var(--border-color));
  background-size: 0% var(--border-width);
  background-repeat: no-repeat;
  color: #f1f2f6;
  text-decoration: none;
  transition: background-size 200ms;
  background-position: 50% calc(100% - var(--bottom-distance));
}

.mainContainer header .navContainer ul.navbar li.rightSide {
  background-position: 100% calc(100% - var(--bottom-distance));
}

.mainContainer header .navContainer ul.navbar li.middle {
  background-position: 50% calc(100% - var(--bottom-distance));
}

.mainContainer header .navContainer ul.navbar li.leftSide {
  background-position: 0 calc(100% - var(--bottom-distance))
}

.mainContainer header .navContainer ul.navbar li:hover {
  background-size: 100% var(--border-width);
}

.mainContainer header .navContainer ul.navbar li.active {
  background-size: 100% var(--border-width);
}

.mainContainer header .navContainer ul.navbar li.navItem a i {
  color: #f1f2f6;
  font-size: 60px;
  display: flex;
  justify-content: center;
  align-items: center;
  background-color: transparent;
}

.mainContainer header .navContainer ul.navbar li.navItem span {
  font-size: 100%;
  background-color: transparent;
  display: block;
}
