Question

What is the process for customizing the onmouseover property in HTML?

I am currently working on customizing tabs. I want to underline the title of the active tab, but for some reason I am having trouble achieving this with CSS. It seems like I might need a CSS syntax that I am not familiar with.

As a solution, I am considering customizing my HTML code with CSS properties. Is there a way to assign the onmouseover, visited, hover, and active attributes to my <div> in HTML?

This is the HTML code I have:

<div class="container">
  <div class="tabcordion">
    <ul class="nav nav-pills nav-stacked col-lg-6 col-md-6 col-sm-6 col-xs-12">
      <li class="active"><a data-target=".KONTAKT">KONTAKT</a></li>
      <li><a data-target=".ÜBER_UNS">ÜBER UNS</a></li>
    </ul>
    <div class="tab-content col-lg-6 col-md-6 col-sm-6 col-xs-12">
      <div class="KONTAKT in active">My content #1.</div>
      <div class="ÜBER_UNS">My content #2.</div>
    </div>
  </div>
</div>

Answer №1

A Simple JavaScript Approach:

Assign a unique class to each tab, such as .option#
Specify that each tab should underline its title and content when clicked.

document.querySelector('.option1').addEventListener('click', function() {
  // Remove underline from any non-selected tab title
  document.querySelector('.option2').classList.remove('underline');
  // Underline the clicked tab title
  this.classList.add('underline');
})
document.querySelector('.option2').addEventListener('click', function() {
  document.querySelector('.option1').classList.remove('underline');
  this.classList.add('underline');
})

.underline {
  text-decoration: underline;
}

<div class="container">
  <div class="tabcordion">
    <ul class="nav nav-pills nav-stacked col-lg-6 col-md-6 col-sm-6 col-xs-12">
      <li class="option1 active underline"><a data-target=".KONTAKT">KONTAKT</a></li>
      <li class="option2"><a data-target=".ÜBER_UNS">ÜBER UNS</a></li>
    </ul>
    <div class="tab-content col-lg-6 col-md-6 col-sm-6 col-xs-12">
      <div class="KONTAKT in active">My content #1.</div>
      <div class="ÜBER_UNS">My content #2.</div>
    </div>
  </div>
</div>

Answer №2

If you have an <a> tag inside your div, consider using inline style tags before the div element like this:

<style type="text/css">
   #your-div-id a:visited {
   }
</style>
<div id="your-div-id"><a href="#">Foo</a></div>

If there is no <a> tag, you can still create a hover effect using the following CSS style:

#your-div-id:hover {
  color: red
}

Unlike an <a> element, a div element does not store visited history. To achieve a similar effect, you can use a bit of JavaScript to store visit events in the browser's persistence layer (such as a Cookie or Storage API). Then, on page load, an initializing JavaScript script can read this information and add a class to the div element accordingly.
