Hide reddit comments by click the side of the comment

gistfile1.js

function hide(obj) {
    $(obj)
    .children('.entry').first()
    .children('.tagline').first()
    .children('.expand').first()
    .click();
}

var shouldClick = true;
var preventClickEvent = false;
$(document).ready(function() {
    $(".comment").click(function(e) {
        try {
            if (!shouldClick) return;
            if (e.currentTarget != e.target) return;
            hide(this);
            e.preventDefault();
            shouldClick = false;
            setTimeout(function() { shouldClick = true; }, 200);
        } catch(err) {}
    });
});

It would be nice to have color on hover only for the side of the comment and nothing else, but I really have no idea how to do that, because there is no element to color there.
