Padding and margin appear different in my Firefox and Chrome unlike my Opera Mini and UC web browser. How can I solve d problem.

Answer 1

You must deal wit the fact that you cannot expect same rendering on different browsers/devices ^^
However, you can try some css resetters, which try to reduce differences between browsers, but you will never have the perfectly same rendering... But start to define explicit margin and padding: this could fix it, as default values tends to not be same in each browsers :P

Answer 2

Study CSS particularly @media for different screen sizes and percentages.

Answer 3

OK. If it works
