Is it possible to edit an element depending on the child it contains?

<div>
    <section id="content-area">Soy el hijo de div</section>
</div>

div < #content-area{
  border: solid 1px red;
}

When we have a child element, in the css we only have to specify who is the father to be able to edit it, in some cases the symbol > (greater than) to determine who is the father and who is the child, and I would like to know if there is any way to edit the father using the identifier of the child, or do not know if there is something similar as I mentioned in the previous css, using the symbol < (less than) where # content-area is child of div , to div to be able to put a red border only when parent of #content-area .

Currently with CSS you can not achieve what you want.

In the fourth-level selectors of CSS the pseudo-clase : has () that allows you to select an element that has the child elements that are passed as a parameter.

Example:

The next selector selects only the <a> elements that contain <img>

a:has(> img)

The problem with this pseudo-clase is that it is not yet supported by any browser:

Therefore the only possible solution is to use JavaScript either native or with some of its libraries, such as jQuery

Example with JavaScript

window.onload = function(){
  var titulo = document.querySelector('h1');

  titulo.parentNode.style.border = 'solid 1px red';
  titulo.parentNode.style.background = '#ccc';
  titulo.parentNode.style.padding = '10px';
}

<div id="contenido">
  <h1>Hola Mundo</h1>
</div>

Example with jQuery

$(document).ready(function(){
  $('h1').parent('#contenido').css({
    'border':'solid 1px red',
    'background': '#ccc',
    'padding': '10px'
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="contenido">
  <h1>Hola Mundo</h1>
</div>

You are developing the "has" selector for css ( link ), but not yet There is no ordinary browser that supports it, it would be like this:

<!doctype html>
<html lang="en">
    <head>
        <title>Hello, world!</title>

        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no">

        <link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-BVYiiSIFeK1dGmJRAkycuHAHRg32OmUcww7on3RYdg4Va+PmSTsz/K68vbdEjh4u" crossorigin="anonymous">
    </head>
    <style>
        div:has(> section#content-area) {
            border: 1px solid red;
        }
    </style>
    <body>

        <div>
            <section id="content-area">Soy el hijo de div</section>
        </div>

        <div>
            <section >Soy el hijo de div falso</section>
        </div>

        <script src="https://code.jquery.com/jquery-3.2.1.min.js" integrity="sha256-hwg4gsxgFZhOsEEamdOYGBf13FyQuiTwlAQgxVSNgt4=" crossorigin="anonymous"></script>

</html>

Although as it is not supported, you only have javascript as suggested by Jorge Luis

Why do not you try to do it with js and jquery, using the "parent" method

<html lang="en">
<head>
  <meta charset="utf-8">
  <title>parent demo</title>
  <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
 
<div><p>Hello</p></div>
<div class="selected"><p>Hello Again</p></div>
 
<script>
$( "p" ).parent( ".selected" ).css( "background", "yellow" );
</script>
 
</body>
</html>
