Can't set font-weight on the :after pseudo-element used on <input> elements

Question

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 */
}

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

Seems to work for me.. 700 makes it bold.. and 100 makes it thin – Bridewell

I'm using chrome (mac) and it doesn't work – Mojave

100 basically means normal weight.. does 700 make it bold for you? look here w3schools.com/cssref/… – Bridewell

I noticed that the content doesn't show up in Firefox, but does in Chrome. The text or the gray background both do not work in FF. – Conservatism

@Conservatism The grey background work's fine for me, it's just the font-weight that isnt working – Mojave

@Mojave I was just pointing it out in case you were worried about browser compatibility. – Conservatism

@Conservatism Yeah I just noticed that it's really messed up in firefox, thanks – Mojave

Answer 1

This was answered here. It seems :after was intended for appending to container tags only. Can I use the :after pseudo-element on an input field?
