CSS Help: Blurred Background behind Category/Topic Lists

I‘m currently trying to replace the white title bar (.d-header) with a blured one. Unfortunately, my code snippet is also bluring all the buttons and text elements. How can I do it the right way?

.d-header{
    background: none;
    box-shadow: none;
    filter: blur(10px);
}

Thanks in advance!
