Jquery css function to dynamically manipulate the style of DOM nodes

The css function in JQuery can set effects for DOM nodes. CSS functions generally have the following uses:
1. Determine whether an object is hidden:

$("#id").css("display")=="none " ;
Second, set the value of a style attribute in all matching elements:
$("div").css("color","#FF0000");
Three, put a "name/value pair" Object set to the style properties of all matching elements. This is the best way to set a large number of style
attributes on all matching elements:
$("div").css({ color: "#ff0000", background: "blue" });
If the attribute name If it contains "-", you must use quotation marks:
$("div").css({ "margin-left": "10px", "background-color": "blue" });
Here are some of what I wrote demo code.

    <script type="text/javascript"> 
        $(function() { 
            // $("div").click(function() { alert($(this).next("div").text()); }); 
            // $("div").click(function() { alert($(this).nextAll("div").text()); }); 
            // $("div").click(function() { $.each($(this).nextAll("div"), function() { $(this).css("background", "red") }); }); 
             
            $("p").click(function() { $.each($(this).nextAll("p"), function() { $(this).css("background", "#abccdd") }); }); 
            $("div").click(function() { $.each($(this).next("div"), function() { $(this).css({ "margin-left": "10px", color: "#abccdd", background: "blue" }) }); }); 
            $("#fristDiv").click(function() { $.each($(this), function() { $(this).css({ "margin-left": "10px", color: "#abccdd", background: "blue" }) }); }); 
            $("#lastDiv").click(function() { $.each($(this), function() { $(this).css({ "margin-left": "10px", color: "#abccdd", background: "blue" }) }); }); 
        }); 
    </script> 
</head> 
<body> 
<div id="fristDiv">aa</div> 
<div>bb</div> 
<div>cc</div> 
<div>dd</div> 
<p>p1</p> 
<p>p2</p> 
<p>p3</p> 
<p>p4</p> 
<div id="lastDiv">ee</div> 
</body> 
</html>
