Trik CSS ini saya dapat atau bersumber dari http://djogzs.blogspot.com ya hitung-hitung untuk nambah pengetahuan :D
Untuk penerapanya sendiri cukup mudah,kamu tinggal copy paste HTML dan CSS dibawah ini.
CSS : diatas code ]]></b:skin>
HTML :letakan diantara kode html/didalam <body> dan </body>
(tergantung kamu mau diletakan dimana.)
HTML
<div id='slider2'>
<div id='mask'>
<ul><li>
<a href='#' title='#'><img src='urlgambar'/></a></li>
<li>

</li>
</ul>
</div>
<div id='progress'>

Oia,untuk slidernya sendiri sudah saya atur agar kecepatan slide'a lebih lambat dari aslinya,yang diatur dengan css keyframe slide-animation.
dan juga menurut saya pemasangan banner ini terbatas,hanya4 buah.kenapa tidak bisa lebih?
sebenarnya bisa,pertama,kamu perhatikan CSS dibawah ini.
@-webkit-keyframes slide-animation {
0% {opacity:0;}
2% {opacity:1;}
20% {left:0px; opacity:1;}
22.5% {opacity:0.6;}
25% {left:-468px; opacity:1;}
45% {left:-468px; opacity:1;}
47.5% {opacity:0.6;}
50% {left:-936px; opacity:1;}
70% {left:-936px; opacity:1;}
72.5% {opacity:0.6;}
75% {left:-1404px; opacity:1;}
95% {opacity:1;}
98% {left:-1404px; opacity:0;}
100% {left:0px; opacity:0;}
}
perhatikan saat 25% dan 45%, left:-468px; .jadi saat css slider sudah difungsikan untuk bergeser ke arah kiri sejauh 468px.
1. maka karena itu jika ukuran gambar tidak tepat/sama,yang terjadi pergerakan slider menjadi tidak sempurna.
2.bila kamu perhatikan,kenapa di timing 47.5% menggunakan opacity?itu hanya perfungsi sebagai fade effect/transparant sesaat akan bergeser.
3.di timing 50% 70% bernilai -936px dan 75% 98% -1404px. kenapa bisa begitu?
itu artinya slide akan selalu bergeser ke arah kiri sejauh -468px.dan selanjutnya juga pindah ke slide selanjutnya,maka akan bergeser lagi sejauh -468px.
begini perhitungan dan teorinya:
-ketika suatu objek digeser kearah kiri,maka akan bernilai minus,maka
0-468 = -468
digeser ke arah kiri lagi menjadi
-468-468 = -936
digeser ke arah kiri lagi menjadi
-936-468 = -1404
lalu di timing 100% kembali ke posisi awal yaitu 0.
nah,jadi bagai mana kalau mau menambahkan slider lagi? kalian harus membuat perhitungan sendiri mulai dari timing 0% sampai 100%.
jadi semoga saja bisa dipahami dari penjelasan saya diatas,pastinya ada hubunganya dengan perhitungan matematika xD
karena jika anda mengerti dengan fungsi diatas,kamu bisa mengatur slide ini sendiri dengan ukuran bebas.
Note:-diatas hanya contoh,karena slider'a ini crossbrowser antara mozzilla dan chrome,maka perhatikan awalan depan css moz dan webkit,nilai'a harus sama.
Untuk pengaturan posisi slidernya,menggunakan margin.ohya klo template crash bukan salah saya jadi kalian harus membaca secara teliti oke selamat mencoba dan belajar
margin:0px 0px 0px 0px;
#slider2 {
width: 468px;
height: 60px;
margin:0px 0px 0px 0px;
overflow: hidden;
background-color: #F8F8F8;
border: 10px solid #F8F8F8;
-moz-transition: all 170ms ease-in;
-webkit-transition: all 170ms ease-in;
-o-transition: all 170ms ease-in;
position: relative;
border-radius: 10px/20px;
}
Setting diatas masih default,kamu tinggal mengatur nilai margin left,top,right dan bottomnya.
