CSS with PHP

PHP is a widely-used server-side scripting language especially suited for web development, powering tens of millions of sites from Facebook to personal WordPress blogs. PHP is often paired with the MySQL relational database, but includes support for most other mainstream databases. By utilizing different Server APIs, PHP can work on many different web servers as a server-side scripting language.

Cascading Style Sheets (CSS) is a language used for describing the look and formatting of a document written in a markup language. Usually used to change web pages and user interfaces written in HTML, it can also be applied to any kind of XML document. CSS is designed primarily to distinguish the content of a document from its presentation.

JavaScript is a dynamic, object-based language commonly used for client-side scripting in web browsers. Recently, server side JavaScript frameworks have also emerged. JavaScript runs on nearly every operating system and  in almost every mainstream web browser.
