Cascading Style Sheets Level 1 (CSS1)

What is Cascading Style Sheets Level 1 (CSS1)?
Cascading Style Sheets Level 1 (CSS1) is a recommendation of the World Wide Web Consortium (W3C), which defined the first version (level) of CSS.

CSS defines the concept of style, in which the style defines the appearance. Any HTML tag can be changed by assigning a specific style. The concept of style optimizes the performance of rendering HTML content and simplifies the work of developers by rendering a style specification uniformly across different browser implementations. CSS consists of selectors and declarations. The declaration is a combination of property and value.

The CSS1 (sometimes CSSL1) was originally recommended on December 17, 1996. The current version is CSS, Level 2 Revision 1 (CSS 2.1).

HTML is the primary markup language involved in web development. However, HTML does not isolate the structure and content of a document. The structure of the document deals with how the page is displayed on the screen, while the content of the web page is the actual data enclosed in the HTML tags. CSS helps loosen the limitations of HTML by giving a designer more control over the look and feel of a page.

Features supported by CSS:

All font-related properties such as size, color, family, etc.

Text color, background color, and any changes associated with images

All related text attributes such as size, letter spacing and alignment

Appearance and formatting of tables and frames

All spacing attributes such as border, filling and border as well as spacing in the horizontal and vertical direction
