What is CSS Cascading Style Sheets in simple words?
Collections of CSS rules included in a style tag
in the head portion of an HTML document. There is no single, integrated CSS4 specification,[52] because the specification has been split into many separate modules which level independently. Values may be keywords, such as "center" or "inherit", or numerical values, such as 200px (200 pixels), 50vw (50 percent of the viewport width) or 80% (80 percent of the parent element's width). In CSS, selectors declare which part of the markup a style applies to by matching tags and attributes in the markup itself. CSS has a simple syntax and uses a number of English keywords to specify the names of various style properties. In addition to HTML, other markup languages support the use of CSS including XHTML, plain XML, SVG, and XUL.
A style can be based on another style, or it can be based on "No style". And styles can be based on styles based on styles, up to 9 levels deep. So a style may have a parent, and a grand-parent; and it may have one or more children. This page explains how the format what is css of paragraph styles cascade. Much the same principles apply to other kinds of styles, except the new List styles introduced with Word 2002.

History of CSS
The body element in our HTML is the parent of all of our other HTML elements (excluding the section). Setting the font property on the body element allows the rest of the document to inherit the font rule. CSS is created and maintained through a group of people within the W3C called the CSS Working Group.
- If multiple CSS rules conflict with one another, the most important or specific selector is the one that will apply.
- The design also uses mortised images on the top half of the homepage to enable users view and click images.
- Cascading Style Sheets level 1 (CSS1) came out of W3C as a recommendation in December 1996.
Each of these elements are possible because of cascading style sheets. Using Cascading Style Sheets (CSS) allows developers to separate content from presentation. In other words, with CSS the visual layout of a Web page can be established with style sheets, while the content can be put into HTML.

It separates the content from the visual representation of the site. The relation between HTML and CSS is strongly tied together since HTML is the very foundation of a site and CSS is all of the aesthetics of an entire website. In the code above, we have created rules for paragraphs to be three different colors.
