Cascading Style Sheets. Cascading: The browser cascades through the various styles set throughout the code. The browser needs to decide which CSS to display, and follows a set of rules to cascade through all of the available CSS. A website can have CSS in multiple external stylesheets as well as inline and embedded CSS. The inline CSS gets a highest priority. More specific CSS also receives a higher priority than less specific CSS. The browser cascades through all of the CSS and decides on the priority if there is conflicting CSS. Stylesheets are used by organizations and publishers. A style sheet will specify how a logo is used and which fonts and colors can be used for the organization's branding. With CSS we use code to create the style sheet.
