Are there any alternative methods to avoid duplication of Navbar link margin classes in Tailwind CSS?

It feels really repetitive to have to add margin classes to each LI manually on a non-dynamically generated menu. It almost seems as messy as using inline style attributes...

Is there a more efficient way to handle this?

While it may not be a big deal for a small menu, the final structure will contain multiple levels of submenus.

I'm considering creating a CSS rule in my stylesheet to automatically apply margins to the menu items instead. What do you think?

<nav class="p-2 bg-indigo-900 text-white">
    <ul class="flex flex-row">
        <li class="mr-1">
            <a href="#">Home</a>
        </li>
        <li class="ml-1 mr-1">
            <a href="#">About</a>
        </li>
        <li class="ml-1 mr-1">
            <a href="#">Services</a>
        </li>
        <li class="ml-1 mr-1">
            <a href="#">History</a>
        </li>
        <li class="ml-1">
            <a href="#">Contact</a>
        </li>
    </ul>
</nav>

Answer №1

If you are not familiar with the tailwind-css framework, you can utilize the :last-child and :first-child selectors to achieve specific styling.

nav ul li {
  margin-left: 10px;
  margin-right: 10px;
}

nav ul li:first-child {
  margin-left: 0px;
}

nav ul li:last-child {
  margin-right: 0px;
}

<nav class="p-2 bg-indigo-900 text-white">
  <ul class="flex flex-row">
    <li class="">
      <a href="#">Home</a>
    </li>
    <li class="">
      <a href="#">About</a>
    </li>
    <li class="">
      <a href="#">Services</a>
    </li>
    <li class="">
      <a href="#">History</a>
    </li>
    <li class="">
      <a href="#">Contact</a>
    </li>
  </ul>
</nav>

After realizing I didn't provide any context about this being a Laravel project, I've decided to mark the answer above as correct. What I've ended up doing is creating a partial for my navigation bar, where I pass it an array of labels and URLs.

// Code snippet from layouts/app.blade.php
@include('layouts._nav', ['links' => [
    [ 'label' => 'Main feed', 'url' => '/posts' ],
    [ 'label' => 'Announcements', 'url' => '/announcements' ],
    [ 'label' => 'Who to follow', 'url' => '/who-to-follow' ],
    [ 'label' => 'Profile', 'url' => '/profiles' ]
]])

// Code snippet from layouts/_nav.blade.php
<nav class="p-2 bg-indigo-900 text-white">
    <ul class="flex flex-row">
        @foreach($links as $link)
            @php
                if($loop->iteration === 1)
                    $class = 'mr-1';
                elseif($loop->iteration === $loop->count)
                    $class = 'ml-1';
                else
                    $class = 'ml-1 mr-1';
            @endphp
            <li class="{{ $class }}">
                <a href="{{ $link['url'] }}">{{ $link['label'] }}</a>
            </li>
        @endforeach
    </ul>
</nav>

Output HTML:


<nav>
    <ul class="flex flex-row">
        <li class="mr-1">
            <a href="/posts">Main feed</a>
        </li>
        <li class="ml-1 mr-1">
           <a href="/announcements">Announcements</a>
        </li>
        <li class="ml-1 mr-1">
            <a href="/who-to-follow">Who to follow</a>
        </li>
        <li class="ml-1">
            <a href="/profiles">Profile</a>
        </li>
    </ul>
</nav>

Styling those components using the 'first' and 'last' pseudo-classes can be a simpler solution compared to others. Here is an example of how you can achieve this in React.js.

<nav className="p-2 bg-indigo-900 text-white">
  <ul className="flex flex-row">
    {["Home", "About", "Services", "History", "Contact"].map(link=>{
      return (
        <li className="first:ml-10 last:mr-10">
          <a href="#">{link}</a>
        </li>
      )
    })
  </ul>
</nav>
