Border-radius and :hover state area issue

I'm looking everywhere to answer this question but nowhere can I find anything about it. Can anyone tell me whether we can affect the area which received the item hover border-radius property. So that the effect of changes such as color took place after hitting a real area viewed item? Do not block that physically exists in the DOM as a square?

This is simple img.

Solution

  • Well, you can use SVG and pointer-events:

    https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events?redirectlocale=en-US&redirectslug=CSS%2Fpointer-events

    Or just use SVG, maybe with some framework like Raphäel.

    Or maybe play with a map, let me try that...

    HTML

    <img class="div" src="http://images2.wikia.nocookie.net/__cb20100822143346/runescape/images/2/21/1x1-pixel.png" usemap="hack"/>

<map name="hack">
    <area shape="circle" coords="200,200,200" />
</map>

    JS

    $('area').hover(function(event) {

    $('img.div').toggleClass('hover');

});

    LOOK MOM, NO JS:

    http://jsfiddle.net/coma/nawAE/12/

    .div {
    display: block;
    font-size: 0;
    width: 400px;
    height: 400px;
    background-color: red;
    border-radius: 50%;
}

map:hover + img {
    background-color: blue;
}

    More of that:
