3.样式：
#div_show { height: 400px; left: 80px; position: fixed; top: 88px; width: 80%; z-index: -100; } .div_show_title { filter:progid:DXImageTransform.Microsoft.gradient(startColorstr='#12a3f4', endColorstr='#0e86c9', GradientType=0); clear: both; display: block; background: rgb(14, 134, 201); color: #FFFFFF; font-weight: 700; position: relative; height: 30px; width: 100%; } .div_show_font { color: #FFFFFF; float: left; font-weight: 700; margin: 0.4em 0 0.4em 10px; } .div_show_btn { float: right; margin: 0.4em 10px 0.4em 0; } #div_hotelmap { height: 360px; border: 5px solid white; }
