Tài liệu Không xài flash. vẫn javascript + css + html theo bài học đổ dữ liệu từ database docx

Không sài flash. vẫn javascript + css + html
theo bài học đổ dữ liệu từ database vào sẽ có được 1 phần giới thiệu ấn tượng
Demo : />Bước 1 : CSS - Copy đoạn code sau dán vào thẻ head
PHP Code:
<style type="text/css">
html {
overflow: hidden;
}
body {
position: absolute;
margin: 0px;
padding: 0px;
background: #111;
width: 100%;
height: 100%;
}
#center {
position: absolute;
left: 50%;
top: 50%;
}
#slider {
position: absolute;
width: 820px;
height: 333px;
left: -430px;
top: -186px;
overflow: hidden;
background: #000;
border: 20px solid #000;
}

#slider .slide {
position: absolute;
top: 0px;
height: 333px;
width: 500px;
background: #000;
overflow: hidden;
border-left: #000 solid 1px;
cursor: default;
}
#slider .title {
color: #F80;
font-weight: bold;
font-size: 1.2em;
margin-right: 1.5em;
text-decoration: none;
}
#slider .backgroundText {
position: absolute;
width: 100%;
height: 100%;
top: 100%;
background: #000;
filter: alpha(opacity=40);
opacity: 0.4;
}
#slider .text {
position: absolute;
top: 1%;
top: 100%;

color: #FFF;
font-family: verdana, arial, Helvetica, sans-serif;
font-size: 0.9em;
text-align: justify;
width: 470px;
left: 10px;
}
#slider .diapo {
position: absolute;
filter: alpha(opacity=100);
opacity: 1;
visibility: hidden;
}
</style>
