No, there is no CSS parent selector. The parent selector allows you to select a parent element based on the characteristics of its child elements. However, CSS currently only has selectors that work from parent to child, not from child to parent.

There are a few workarounds that can achieve similar effects. For example, you can use JavaScript to add a class to a parent element based on the characteristics of its child elements, and then use CSS to style that parent element based on the added class. Another workaround is to use a nested selector to select the child element and its parent element together, and then apply styles to both of them.

However, it is important to note that using these workarounds can have performance implications, especially if the page has a large number of elements. It is generally recommended to avoid relying on parent selectors in CSS, and to instead use more specific selectors and/or restructure your HTML to achieve the desired effect.
