As a web developer, I recently had the opportunity to explore the new LOGIN PAGE preview of GMAIL and was very impressed with the Sign In button's UI. After examining the Page's CSS, I discovered some interesting properties, such as:
**background-color: #4D90FE;
background-image: -webkit-gradient(linear,left top,left bottom,from(#4d90fe),to(#4787ed));
background-image: -webkit-linear-gradient(top,#4d90fe,#4787ed);
background-image: -moz-linear-gradient(top,#4d90fe,#4787ed);
background-image: -ms-linear-gradient(top,#4d90fe,#4787ed);
background-image: -o-linear-gradient(top,#4d90fe,#4787ed);
background-image: linear-gradient(top,#4d90fe,#4787ed);**
I am now seeking advice on how to optimize the page for all major browsers using these CSS extension properties. Is there a reference link available for these extensions or any other useful resources?
Thank you.
