只需从 jquery-ui css 中提取所需的图标位置:

CSS:

.ui-icon { 
    width: 16px; 
    height: 16px; 
    background-image: url("http://code.jquery.com/ui/1.9.1/themes/base/images/ui-icons_454545_256x240.png");
}
      

        
.ui-icon-arrowthick-1-n { background-position: 0 -48px; }
.ui-icon-arrowthick-1-ne { background-position: -16px -48px; }
.ui-icon-arrowthick-1-e { background-position: -32px -48px; }
.ui-icon-arrowthick-1-se { background-position: -48px -48px; }
.ui-icon-arrowthick-1-s { background-position: -64px -48px; }
.ui-icon-arrowthick-1-sw { background-position: -80px -48px; }
.ui-icon-arrowthick-1-w { background-position: -96px -48px; }
.ui-icon-arrowthick-1-nw { background-position: -112px -48px; }
.ui-icon-arrowthick-2-n-s { background-position: -128px -48px; }
.ui-icon-arrowthick-2-ne-sw { background-position: -144px -48px; }
.ui-icon-arrowthick-2-e-w { background-position: -160px -48px; }
.ui-icon-arrowthick-2-se-nw { background-position: -176px -48px; }

要获取图标的名称，请转到 theme rolling page将鼠标悬停在您需要的图标上，打开 css 文件，在那里找到图标的名称，将代码复制到您的新 css。
