I am here not talking about Server-side improvements. I am here talking about Front-End improvements that really affects the web page speed.
The time spent till the website is running on the client’s browser. If we analyze that time, we will get:
Request Time (in milliseconds)
Server Process Time, or response time (usually in milliseconds)
Downloading web page and files into browser (few to several seconds, depending on internet speed)
Rendering on browser.
Drang n’ Drop in HTML 5 is supported by: IE9+, Firefox 3.6+, Safari 4+, Opera 11+ and Chrome 12+. But its not supported yet for touch devices like Touch Mobiles and Tablets.
Every browser has different CSS properties for less-used actions like: transparency or opacity.
It was something weird to do transparency on your web page because there are lot of different web browsers. To make that easy, I have collected information and generated a CSS class that will work on most of the browsers.
See the Code below:
filter:alpha(opacity=75); is used for Internet Explorer.
-moz-opacity:0.75; is used for Mozilla, Firefox, Netscape browsers (old versions).
-khtml-opacity: 0.75; is used for old versions of Safari.
opacity: 0.75; is used as a standard CSS property for browsers like Firefox 2+ and Safari 3+ and Opera
