"Utilize the CSS inheritance feature to inherit properties from parent

I am looking to add a border-bottom to a header element with the same color as its child font. Can you please provide me with the HTML code and guide me on how to proceed?

<header>
  <div class="cblt-panel">
     <header>
          <a href="HomePage;jsessionid=9Z1DRLtK8FfgmVDhysv4fk8LKjj1rTpSpJcS99dvcbffT4KTZ9tN!91184445">
             <div class="header-wrapper header"> 
                <h1 class="dealer-name">Airport Chevrolet Cadillac</h1>
            </div>
          </a>

     </header>

   </div>
</header>

In the provided markup, I aim to set the border-bottom-color of the outer header tag to match the font color of the child h1 tag. Is this achievable?

Answer №1

Using only CSS may not be the best way to achieve this. Fortunately, incorporating jQuery can make things easier:

let headingColor = $('.dealer-name').css('color');
$('header:eq(0)').css('border-bottom-color', headingColor);

See it in action here: http://jsfiddle.net/S9svs/

Answer №2

Unfortunately, CSS does not allow parents to inherit styles from their children.

One workaround is to match the border color of an element to its own text color by omitting the border color setting altogether. However, if you need to use a child's color, JavaScript is required.

A more effective approach is to coordinate the styles by assigning the same color value to both a heading element and its parent container. Remember to apply these settings in separate rules, such as

header { border-color: #060; } h1 { color: #060; }
.

Answer №3

To create dynamic styles, utilizing a css preprocessor language is essential...

An option is Less CSS

This allows for the dynamic definition of css, similar to how it's done in javascript...

For instance,

@color:#000;
header { border-bottom-color:@color; }
header h1 { color:@color; }

Answer №4

Interestingly, the border-color property actually takes on the color defined in the color property if it is not explicitly set. This means that in certain situations, you can achieve the opposite effect. For example:

header {
    color: red;
    border-bottom: 2px solid;
}

header a, header h1 {
    color: inherit;
}

Check out the DEMO here: http://jsfiddle.net/brTTT/

In the demo, hover over to see the color change simply by adjusting the color property of the header.
