Difference between CSS & PHP

CSS & PHP both use for web development..

CSS - cascading style sheets are used for styling an (x)html web page
PHP - PHP Hypertext Preprocessor (or Personal Home Page as originally designated) is a server side processing language.

First of all let us see what is CSS?

• CSS determined by Font size , font type, font color , font shape ,borders & styling around images , page layout, mouse – over effects and more ..
• CSS manages & expresses how HTML elements are to be displayed.

• Styles are normally saved in external .css files. External style sheets enable you to change the appearance and layout of all the pages in a Web site, just by editing one single file.
• The colors, fonts and styles of this entire website are driven by Using CSS.

What is PHP?

• PHP is original meaning “Personal Home Page”, PHP can make the webpage do mess.
• To describe what a PHP page is, you could say that it is a file with the extension .php that contains a combination of HTML tags and scripts that run on a web server.
• In an HTML document, PHP script (similar syntax to that of Perl or C ) is enclosed within special PHP tags. 

Finally I can explain this by using simple  example.

If we get a Plane for an example, 

CSS provides the style ,shape , general look and feel, nice air plane .

PHP makes a website do stuff, like a plane engine and rpm...
