Hi everyone

I need a simple help to design my autocomplete div from a input text file, i have this code but the width and height are not working.

I want to create a css file and write some css to design my autocomplete box but i dont know how i can do it.

I have this code:

PHP Code:
<script>    
$(function() {
        var 
availableTags = [
            
"ActionScript",
            
"AppleScript",
            
"Asp",
            
"BASIC",
            
"C",
            
"C++",
            
"Clojure",
            
"COBOL",
            
"ColdFusion",
            
"Erlang",
            
"Fortran",
            
"Groovy",
            
"Haskell",
            
"Java",
            
"JavaScript",
            
"Lisp",
            
"Perl",
            
"PHP",
            
"Python",
            
"Ruby",
            
"Scala",
            
"Scheme"
        
];
        $( 
"#Search" ).autocomplete({
            
sourceavailableTags,
            
width:  400,
            
height:400
        
});
    });
</script> 
If anyone can give me a help with that will be really great for me, thanks community
