Css Introduction

Hello guys morning and welcome to another whole new section of my tutorial. For those of you that have being following up with my tutorials, you all know that we have completed our tutorials on HTML and in this tutorial i want to introduce Cascading Style Sheets (CSS) to you guys.

Cascading Style Sheets, generally referred to as CSS, is a simple design language meant for the purpose of simplifying the process of making web pages presentable.

CSS handles the look of a web page. Using CSS, you can control the color of the text, the style of fonts, the spacing between paragraphs, how columns are sized and laid out, what background images or colors are used, as well as a variety of other effects.
CSS is a very easy language to learn and understand but it provides a powerfull control over the presentation of a HTML document. Most commonly, CSS is combined with the makeup languages HTML or XHTML.

Advantages of CSS

  • CSS saves time - You can write CSS once and then reuse the same sheet in multiple HTML pages. You can define a style for each HTML element and apply it to as many web pages as you want.
  • Easy maintenance - To make a global change, simply change the style, and all the elements in all the web pages will be updated automatically.
  • Pages load faster - If you are using CSS, you do not need to write HTML tag attributes every time. Just write one CSS rule of a tag and apply it to all the occurrences of that tag. So less codes means faster download times.
  • Superior style to HTML - CSS has a much wider array of attributes than HTML, so you can give a far better look to your HTML page in comparison to HTML attributes.
  • Global web standards - Now HTML attributes are being deprecated and it is being recommended to use CSS. So it's a good practice to start using CSS in all the HTML pages to make them compatible with future browsers.
  • Multiple Device Compatibility - Style sheets allow content to be optimized for more than one type of device. By using the same HTML document, different versions of a website can be presented for handheld devices such as PDAs and mobile phones or for printing. 

Who Creates and Maintains CSS?

Css is created and maintained through a group of people within the W3C called the CSS Working Group. The CSS Working Group creates documents called specifications. When a specification has been discussed and officially ratified by the W3C members, it becomes a recommendation.

These ratified specification are called recommendations because the W3C has no control over the actual implementation of the language. Independent companies and organizations create that software.

NOTE: The World Wide Web Consortium or W3C is a group that makes recommendations about how the Internet works and how it should evolve. 

CSS Versions

Cascading Style Sheets level 1 (CSS1) came out of W3C as a recommendation in December 1996. This version describes the CSS language as well as a simple visual formatting model for all the HTML tags.

Cascading Style sheets (CSS2) became a  W3C recommendation in May 1998 and builds on CSS1. This version adds support for media-specific style sheets e.g printers and aural devices, downloadable fonts, element positioning and tables.
