Selecting an element that doesn't have a child with a certain class

问题

The structure of my HTML is like so

<div>
    <div>
        <h1>Something</h1>
    </div>
    <div>
        <h1 class='Handle'>Something</h1>
    </div>
</div>

In the event that the div > div does not have a child with the class "Handle" I want the the div > div to have the style cursor:move;. How would I go about doing this in pure CSS, is it even possible?

回答1:

This would work, except no browser currently supports it as far as I am aware. jQuery does though, however.

div > div:not(:has(h1.Handle)) {
    cursor: move;
}

There is no parent selector in CSS, so what you are asking is not possible. What you can do is put the cursor:move on every h1 that doesnt has the class "Handle" by using the attribute selector.

h1:not([class=Handle]) {
    cursor:move;
}

Another option is to adjust your HTML, and move your h1 on the same level as the div.

<div>
    <h1>Something</h1>
    <div>
        dragable content
    </div>
    <h1 class='Handle'>Something</h1>
    <div>
        non dragable content
    </div>
</div>

Now you can do the same check on the h1, and target the div that comes after it.

h1:not([class=Handle]) + div {
    cursor:move;
}

Try

div > div h1:not([class=Handle]) {
    cursor:move;
}
