为什么即使使用相同的CSS也会有不同的结果？

Question

I copied a PHP web system which made 10 years ago on Linux to my windows PC.

I installed PHP 5.6.2 on my windows PC And It is higher than installed Linux. (old system's PHP is 5.1.4)

But when i compared two web site, they were different a little.

This is the old php in Linux system.

And this is new system.

Do you know difference? The old system's text of menu aligned to center.

But new system's aligned right a little from center.

So i checked css, But these css are same.

somebody know about this?

Answer 1

Assuming you have the same HTML DOM, CSS and running the two system on the same browser, browser version and browser compatibility mode..

Have you checked if they are having the same values for the following?

• HTML doctype
• X-UA-Compatibility meta type
