jquery apply custom icons

My application is an old one and did not use the jQuery well. But I used jQuery Accordion in one of my pages.

I can not include all the style which has written in "jquery-ui-1.8.13.custom.css". So I have to customize it, so that it only contain the style needed to set the appearance of Accordion. What line of contents should not I remove ?

jQuery code:

var icons = {
            header: "ui-icon ui-icon-circle-arrow-e",
            headerSelected: "ui-icon ui-icon-circle-arrow-s"
        };

        // Accordion for Router Configuration and UNC Image Reopsitory
        $("#dvAccordion").accordion(
        { autoHeight: false,
            collapsible: true,
            icons: icons
        }
    );

Contents on my css file

    .ui-accordion { width: 100%; }
/*border-color:#adb0b3; */
.ui-accordion .ui-accordion-header {border-color:#adb0b3; border-width:1px; border-style:solid;  margin-left:20px; margin-right:20px; cursor: pointer; position: relative; margin-top: 1px; zoom: 1; background-color: #535353; color:White;}
.ui-accordion .ui-accordion-li-fix { display: inline;   }
.ui-accordion .ui-accordion-header-active { border-bottom: 0 !important; }
.ui-accordion .ui-accordion-header a { text-decoration:none;   font-family:Verdana,Tahoma,Arial; font-style:inherit; display: block; font-size: 1em; padding: .5em .5em .5em .7em; color:White;}
.ui-accordion-icons .ui-accordion-header a { padding-left: 2.2em; }
.ui-accordion .ui-accordion-header .ui-icon { position: absolute;开发者_StackOverflow left: .5em; top: 50%; margin-top: -8px; }
.ui-accordion .ui-accordion-content { padding: 1em 2.2em; border-top: 0; margin-top: -2px; position: relative; top: 1px; margin-bottom: 2px; overflow: auto; display: none; zoom: 1; }
.ui-accordion .ui-accordion-content-active { display: block; }

/* states and images */
.ui-icon { width: 16px; height: 16px; background-image: url(Icons/jquery/ui-icons_222222_256x240.png); }
.ui-widget-content .ui-icon {background-image: url(Icons/jquery/ui-icons_222222_256x240.png); }
.ui-widget-header .ui-icon {background-image: url(Icons/jquery/ui-icons_ffffff_256x240.png); }
.ui-state-default .ui-icon { background-image: url(Icons/jquery/ui-icons_ef8c08_256x240.png); }
.ui-state-hover .ui-icon, .ui-state-focus .ui-icon {background-image: url(Icons/jquery/ui-icons_ef8c08_256x240.png); }
.ui-state-active .ui-icon {background-image: url(Icons/jquery/ui-icons_ef8c08_256x240.png); }
.ui-state-highlight .ui-icon {background-image: url(Icons/jquery/ui-icons_228ef1_256x240.png); }
.ui-state-error .ui-icon, .ui-state-error-text .ui-icon {background-image: url(Icons/jquery/ui-icons_ffd27a_256x240.png); }

/*set icons for Accordion*/
.ui-icon-circle-arrow-e { background-position: -112px -192px; }
.ui-icon-circle-arrow-s { background-position: -128px -192px; }
.ui-icon-circle-arrow-w { background-position: -144px -192px; }
.ui-icon-circle-arrow-n { background-position: -160px -192px; }

And placed jQuery images on Icons/jquery/. It forms a perfect Accodion, but I could not set the icons. Why ?

You have to put this MINIMUM CSS for your accordion & icons to work
