আসসালামুয়ালাইকুম। কেমন আছে আপনারা? আশা করি ভাল আছেন। এই মাত্র নামাজ পরে আসলাম। পিসি তে বসেই ভাবলাম একটা টিউন্স করব।তাই লেখা শুরু করলাম।জানি না কেমন লাগবে। ভাল লাগলে জানাবেন। এতে লেখার আগ্রহ পাওয়া যায়। যাইহোক, আজ ব্লগ বা ওয়েবসাইট কিভাবে সুন্দর করা যায় তা নিয়ে লিখব।একটা ব্লগ এ যদি Image Slideshow থাকে তাহলে ব্লগ টা অনেক সুন্দর দেখায় এবং ভিজিটর দের সাইটে আবার ফিরে আনে।

//** Featured Content Slider script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com.
//** May 2nd, 08'- Script rewritten and updated to 2.0.
//** June 12th, 08'- Script updated to v 2.3, which adds the following features:
 //1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later.
 //2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former).
 //3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example.

//** July 11th, 08'- Script updated to v 2.4:
 //1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider")
 //2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads.
