    What does CSS selector "input+select" mean?

    Hi there,

    What do the selector "input+select" and "input+input" mean in the following css code? What is + sign here for?

    Code:
    input+select, input+input {
       margin-left: 20px;
    }
    Check the following code, what's fit in the selector or what is the portion of the html selected by the code? Thanks,

    Code:
    <!DOCTYPE html>
    <html>
    <head>
    	<title>Car Picker</title>
    	<link rel="stylesheet" href="script06.css">
    	<script src="script10.js"></script>	
    </head>
    <body>
    <h2 class="centered">Car Picker</h2>
    <form action="someAction.cgi">
    	<p><label for="emailAddr">Email Address:
    		<input id="emailAddr" type="text" size="30" class="reqd email">

    the + symbol is used for when two elements appear next to each other, for example the following would add a margin-top to every paragraph apart from the first one

    p + p { margin-top: 10px;}

    Thanks, daniel, let's see if I understood your statement. For selector input+select, is the following met? Because between <input ..> and <select ...>, there are other text: "</label></p><p><label for="color">Colors: ".
    Code:
    	<p><label for="emailAddr">Email Address:
    		<input id="emailAddr" type="text" size="30" class="reqd email">
    	</label></p>
    	<p><label for="color">Colors:
    		<select id="color" class="reqd">
    			<option value="" selected>Choose a color</option>
    			<option value="Red">Red</option>
    			<option value="Green">Green</option>
    			<option value="Blue">Blue</option>
    		</select>

    I don't think so. I'll set up something in fsFiddle.

    Also, I don't understand why paragraph tags are used there - if it is to separate lines then DIVs would be more appropriate I feel.

    I have used the direct descendant selector which is >

    Does this help?
