CSS attribute selector for non-empty attributes

问题:

Is there a CSS selector that applies to non-empty attributes? Using :not([Data-Attribute='']) matches if the attribute is non-existing, too.

I'm looking for something like [Data-Attribute!=''].

回答1:

try this

<style>
    [Data-Attribute]:not([Data-Attribute=""])
    {
        background-color: Red;
    }
</style>
