How to zoom an input radio button element in a deprecated way that is supported by Opera version 11?

Question

I am developing a web application for a device which only supports Opera version 11. Because of this there are some CSS features that I cannot use.

Currently I am working on a form with input radio buttons which size I want to increase. The CSS method zoom (200%) does exactly what I want, but it is too new for the Opera browser. (https://caniuse.com/#search=zoom) Is there a deprecated way of accomplishing this?

Answer 1

The trick is to add border, it will not work without it on Opera 11

#rdBtn{
    border:0px solid red;
    height:50px;
    width:50px;
}

<form>
   <input type="radio" id="rdBtn" />
</form>
