No, there is no parent selector in CSS.

CSS selectors allow you to select elements based on their tag name, class, and id, as well as their attributes and their relationship to other elements in the DOM (Document Object Model). However, there is no way to select an element based solely on its relationship to its parent element.

You can select an element based on it's relationship to other elements, using CSS combinator selector. CSS combinator selectors allow you to select elements based on their relationship to other elements. Here are some examples:

element > element - Selects all direct children of the first element
element + element - Selects the element that is immediately preceded by the first element
element ~ element - Selects all siblings of the first element that come after it
You can also use the :parent pseudo-class, which matches an element that has one or more child elements.

:parent {

  /* styles */

}

However, it is not widely supported in most of the browsers.

Alternatively, You can use JavaScript or jQuery to achieve this.

With JavaScript, you can use the parentNode property to select the parent of an element and apply styles to it. For example:

const element = document.querySelector("#example-element");

const parent = element.parentNode;

parent.style.color = "red";

With jQuery, you can use the parent() method to select the parent of an element and apply styles to it. For example:

$("#example-element").parent().css("color", "red");
