CSS data attribute conditional value selector?

Question

Given html such as :

<div data-points="800">Jonh</div>
<div data-points="200">Jack</div>
<div data-points="1200">Julian</div>

How to select elements were the value is superior to 1000 (x>1000) ?

Preference : via CSS selectors. If no such thing, then I will re-ask for a JQuery / JS answer.

Eventually used :

var x = 1000;
$("div").each(function() {
    if ($(this).attr('data-points') > x) {
        $(this).addClass('larger-than-x'); // Or whatever
    }
});

Answer 1

With CSS you can select elements with their attributes:

div[data-points] {  }

or the value of their attributes:

div[data-points="800"] {  }

but you can't use conditions in CSS.
I would recommend you to use a javaScript solutions for this problem which can be so easy, for example, using jQuery you can do something like:

$("div[data-points]").each(function() {
    if ($(this).attr('data-points') > 1000) {
        $(this).addClass('larger-than-1000'); // Or whatever
    }
});
