Only 1 stylesheet, but you can have multiple stylesheets to styel according to browser types/versions, or by the many media types.
Cascading Style Sheet, or CSS, is a web standard to describe the presentation semantics of a document written in a markup language. In web design CSS is used to separate the document presentation from the document content. CSS specifies a priority scheme in how rules are to be used, thus the cascading effect that is referred to in the name Cascading Style Sheet.
Cascading is related to the way you can set up styles to overwrite each other. There are three types of writing styles. 1. Inline Inline styles are written in the middle of the code, and set the style for that specific tag. 2. Head Head styles are written in the head part of the page. They are overwritten by any inline styles. 3. External External styles are kept in a separate file which is referred to. They are overwritten by any head or inline styles.

Hakon Wium Lie, who was working at CERN in 1994, realized that there was no way to style web documents. The style sheet was not an entirely new idea, as Tim Berners-Lee had written the NeXT browser/editor in a way that allowed it to determine the style with a simple style sheet. However, he did not publish the syntax, as he believed each browser should decided how to best display pages. Other browsers such as Harmony and Viola had comparable style sheets. Instead of more advanced style sheets, however, browsers that followed offered fewer options for stylizing. In fact the NCSA Mosaic browser, which made the web popular, only allowed for changing certain colors and fonts. In 1994, Hakon Wium Lie published the first draft of Cascading HTML Style Sheets (CHSS). This early version was 1 of 9 types of style sheets submitted to W3C. Bert Bos, who was working on the Argo browser which used its own form of a style sheet, SSP, joined forces with Lie to develop the CSS standard. Lie's proposal was presented at the Mosaic and the Web conference in Chicago in 1994, and again in 1995 with Bert Bos. In 1995, W3C set up the HTML Editorial Review Board. Style sheets were in the sphere of interest the members, so CSS was taken up by them as a work item. CSS1 was completed in 1996, and Internet Explorer 3, released the same year, featured limited support for the style sheet. It would be 3 years, however, before any browser would have full support for CSS1. IE 5, released in 2000, was the first browser to have full support. In 2008, IE 8 offered support for CSS 2.1. CSS 3 was released in June of 2012, and is still under development. IE 10 was the first browser to offer support for CSS 3. As a direct answer to your question, Hakon Wium Lie began development of CSS in 1994, and Bert Bos joined him soon after.
