What is the full form of CSS

CSS: Cascading Style Sheets

CSS stands for Cascading Style Sheets. It describes how Html elements should be displayed on the screen. It is a powerful tool for web designers to change the design and control over web pages that how they should be displayed. It is supported by all browsers and is designed primarily to separate the document content from the document presentation.

It was developed by W3C (World Wide Web Consortium) in 1996. The term cascading in CSS implies the fact that you can apply multiple style sheets to a single web page. The extension used to save CSS files is ".css".

CSS Framework

CSS frameworks are pre-defined libraries, including:

  • Blueprint
  • Cascade Framework
  • Foundation
  • Bootstrap.


  • A global style sheet can be used in CSS so that you can make some changes in the style without much difficulty and consume less time.
  • You may create one external style sheet and can use it for many web page styling.
  • You can attach a different style sheet to a web page by just changing one line.

CSS Syntax

The CSS syntax comprises a set of rules. The rule set has 3 parts, a selector, a property, and a value, as shown below:

  • h1 is the selector
  • color and font size are properties
  • blue and 12px are value.

The part of syntax that contains the properties and values is known as Declaration Block.

Advantages of CSS

  • Saves time: It allows you to define a style for each HTML element. You can apply this style to as many web pages as you want.
  • Easy maintenance: You can easily update document formatting and maintain consistency in multiple documents.
  • Faster page loading: It allows multiple pages to share formatting that reduces file transfer size, which helps pages load faster.
  • Platform Independence: It offers platform independence and also supports the latest browsers.
  • Multiple device compatibility: It allows you to optimize content for more than one type of device. You can present an HTML document in different viewing styles for different devices like computers, cell phones, and printers.
  • Superior styles to HTML: It has more presentation capabilities than HTML. It allows you to enhance the look of your HTML pages better than using HTML presentational elements and attributes.

CSS Styles: Internal, External, and Inline

Let us now discuss the various CSS styles. Inline, External, and Internal are them. Each style will be briefly discussed;

Internal: Let us begin by discussing the internal style. This approach to CSS styling involves loading the styles each time a webpage is reloaded, which may lengthen the loading time. Additionally, because it is contained to a single page, you will not be able to utilise the same CSS style on other pages. However, there are advantages to this as well. Sharing the template for a preview is simpler when everything is on one page.

External: The most practical approach could be the external one. On the a.css file, everything is done outside. This implies that you may style every page separately and then apply the CSS to whichever page you choose. The External style could save loading times as well.

Inline: Finally, we shall discuss CSS's Inline style. Only certain components with style> tag support inline. It might not be the most efficient or quick technique to manage CSS because each component needs to be styled. But it could be useful. For instance, you might not have access to the CSS files, or you might only want to rapidly examine modifications to a single element.
