Tips for adding style to the first list element and first children using jQuery

Tips for adding style to the first list element and first children using jQuery

Looking at the following markup:

<ul>
  <li> // this
    <ul>
      <li>
        <div></div>
      </li>
      <li>
        <div></div>
      </li>
    </ul>
  </li>
  <li> // this
    <ul>
      <li>
        <div></div>
      </li>
      <li>
        <div></div>
      </li>
    </ul>
  </li>
</ul>

In my CSS style, I currently have:

.main_menu ul > li {
   // some style
}

This applies the style only to the first li in the hierarchy, not its children. So, my question is how can I achieve this using jQuery? When I try with $('.main_menu ul > li');, it doesn't work. I assume that I need something like this:

$('.main_menu ul').each().first().child();

However, this code is incorrect. Can anyone provide guidance on how to accomplish this?

If you're looking to achieve this effect using only CSS3, it is possible, but keep in mind that the support for certain features may not be universal.

One approach is to utilize the :first-child selector, which allows you to target specific elements. This selector is not exclusive to CSS and can also be used with jQuery as explained here.

For example, ul li:first-child would target the first list item within an unordered list:

<ul>
  <li>             //this
    <li>
      <div></div>
    </li>
  </li>
  <li>             
    <li>
      <div></div>
    </li>
  </li>
</ul>

The usage of > selects all immediate children rather than just the first child. For instance, ul > li targets direct list items like so:

<ul>
  <li>             //this
    <li>
      <div></div>
    </li>
  </li>
  <li>             // this
    <li>
      <div></div>
    </li>
  </li>
</ul>

Answer №2

Have you tested out this CSS selector yet?

.nav_menu ul li:first-child {
   // add your styles here
}

No need for jQuery with this approach!

Furthermore, as mentioned in the feedback, your HTML structure is incorrect. Make sure each nested <li> is enclosed within another <ul>, showcasing like this:

<ul>
    <li></li>
    <li>
        <ul>
            <li></li>
            <li></li>
        </ul>
    </li>
    <li></li>
</ul>
