    Question is asking for two different things:

    1. An element has certain class
    2. An element has certain style.

    Second question has been already answered. For the first one, I would do it this way:

    if($("#someElement").is(".test")){
        // Has class test assigned, eventually combined with other classes
    }
    else{
        // Does not have it
    }

    i've found one solution:

    $("#someElement")[0].className.match("test")
    

    but somehow i believe that there's a better way!

    if ($("element class or id name").css("property") == "value") {
        your code....
    }

    Or, if you need to access the element that has that property and it does not use an id, you could go this route:

    $("img").each(function () {
            if ($(this).css("float") == "left") { $(this).addClass("left"); }
            if ($(this).css("float") == "right") { $(this).addClass("right"); }
        })

    if($('#someElement').hasClass('test')) {
      ... do something ...
    }
    else {
      ... do something else ...
    }

    CSS Styles are key-value pairs, not just "tags". By default, each element has a full set of CSS styles assigned to it, most of them is implicitly using the browser defaults and some of them is explicitly redefined in CSS stylesheets.

    To get the value assigned to a particular CSS entry of an element and compare it:

    if ($('#yourElement').css('position') == 'absolute')
    {
       // true
    }
    

    If you didn't redefine the style, you will get the browser default for that particular element.
