CSS Full Form: The full form of CSS refers to Cascading Style Sheets. CSS is used to define writing styles for presenting documents written in a markup language. This article includes the full form of CSS and explains how we can use CSS, the types of CSS, and its advantages and disadvantages.

What is CSS?

Håkon Wium Lie introduced CSS in 1994. W3C specified CSS in the year 1996. It enables web developers to alter the layout and attributes of their web pages. For example, CSS may be used to change the font, size, and color used in a certain HTML element. A single CSS file may be linked to multiple pages, which allows a developer to change the appearance of all the pages simultaneously. Thus the amount of styling work is saved, and repetition is eliminated.

A CSS file can be created using any text editor or even Notepad in Windows. 

Types of CSS

There are the following three types of CSS:

  • Inline CSS
  • Internal CSS
  • External CSS
  • Inline CSS- In Inline CSS, a unique style is applied to one element at a time. It is used to preview the changes quickly and add CSS to one or two-element. The use of inline CSS helps in improving website speed performance.
  • Internal CSS Internal CSS resides in the head of the document. Internal CSS is used when a style is to be used in the complete HTML body. This CSS style affects only the tags on the page in which they are embedded. 
  • External CSS-This is a style initially written in a separate document and then attached to various web documents. It affects any documents to which they are attached by changing one style sheet.


CSS allows code to define fonts, the color of hyperlinks, and a link when the mouse cursor hovers over it. We are only changing the HTML tags <a> and <body> in this specific example rather than creating any new class or id selectors.

Using CSS mainly enables the separation of document content, focusing on appearance and formatting. CSS can reduce the size, clutter, and load time of web pages. Additionally, it enables multiple pages to share formatting and reduces complexity and repetition in the structural content. 

Advantages of CSS

  • CSS enables to alter the contents of numerous pages of a website by defining the changes in a single CSS file, thus saving time and manual efforts.
  • Uniform and consistent changes are applied on all the pages with a single style sheet.
  • A few lines of code can make changes to many pages on the website with CSS, making the website database remain uncluttered, thus, eliminating any website loading issues.
  • CSS changes are device friendly as CSS serves the purpose by making web pages more responsive so that they can be displayed in the same manner on all devices.
  • With better-defined web page attributes, CSS makes a website SEO friendly.

Disadvantages of CSS

  • Beginners and non-developers find it difficult to adapt to complicated multi-level programming languages
  • The working of CSS varies with the browsers. Thus change effects might not be compatible with every website in the same manner.
  • CSS, being an open text-based system, makes the files vulnerable to any accident or immoral intentions, thereby disrupting the display and formatting of the entire website by making any changes.
