Highlight label if checkbox is checked (html/css)

I would like label to get a red border if radio is checked.

Code so far:

HTML:

<center style="margin-top:20px;">

<label class="big">
This is a box 1
<input name="radio-group1" type="radio" />
</label>

<br/>

<label class="big">
This is a box 2
<input name="radio-group1" type="radio" class='sex' />
</label>

</center>

CSS:

.big {
    display:block;
    width:100px;
    height:100px;
    background-color:gainsboro;
    cursor:pointer;
}

.big:hover {

    border:1px solid blue;
}

No JS solutions please. I have been trying with sibling and children selectors but unsuccesfuly.

You would have to rearrange the HTML so the label/red-border-element comes after the radio.

HTML

<center style="margin-top:20px;">

<div class="big">
    <input id="box1" name="radio-group1" type="radio" />
    <label for="box1">This is a box 1</label>
</div >

<br/>

<div class="big">
    <input id="box2" name="radio-group1" type="radio" />
    <label for="box2">This is a box 2</label>
</div >

</center>

CSS

.big {
    display:block;
    width:100px;
    height:100px;
    background-color:gainsboro;
    cursor:pointer;
    position: relative;
}

.big:hover {

    border:1px solid blue;
}


label {
    width: 100%;
    height: 100%;
    display: block;
}

input[type="radio"] {
    position: absolute;
    top: 20px;
    left: 50%;
}

input[type="radio"]:checked + label {
    border: red 1px solid;
}

But it starts getting weird. A little javascript wouldn’t hurt.

edit: this version is a little cleaner
