So, i've got a custom style on an input element, and I want to place some text on the input with the use of :after.
The problem i'm running into is that i cannot seem to change the font-weight on the :after element, this problem only occurs with the combination of input and :after elements.
CSS
input[type="checkbox"] { /* enable styling of the checkbox ! */
    -moz-appearance: none;
    -webkit-appearance: none;
}
input { /* set up some basic styles.... */
    background-color:#ccc;
    width:200px;
    height:200px;
    background-color:grey;
}
input:after { /* and we create the :after element */
    width:100%;
    text-align:center;
    font-weight:100; /* THIS DOESN'T WORK FOR SOME REASON */
    content: "This should be thin"; /* some text */
}

QUESTION
Why can't I set font-weight on the :after element set on an input element?
