Browser extensions like Stylish and Stylus have been created to facilitate the management of such user style sheets. Cascading Style Sheets (CSS) is a programming design language that includes all relevant information relating to the display of a webpage. CSS defines the style and formatting of a website or page, including the layout, colors, fonts, padding (the space around each element) and more. CSS (cascading style sheets) works in conjunction with HTML and is directly responsible for dictating color, background, text color, font, positioning and additional features to the web browser.

Internal or embedded CSS

So, HTML structures web pages with elements like headers, paragraphs and lists while CSS contains the style information for those structures. While neither HTML or CSS is more complex than the other in terms of syntax, a major difference is that HTML can contain CSS within its code and files, but CSS cannot contain HTML. Both HTML and CSS are mutually containing, however, meaning CSS and HTML share tag names with each other. The following box contains an example of using CSS code to define fonts, the color of hyperlinks, and the color of a link when the mouse cursor hovers over.

CSS documents are used to define the style of a webpage, and are then linked to the HTML document (or a document in different markup language) which contains the content and structure of the page. Setting the style directly in the HTML document is possible, but not recommended. CSS2, an evolution of CSS, incorporated media queries to allow developers to specify triggers for certain styles to take effect. For example, it can present a printer-friendly version of the page when requested. CSS3 took this a step further by introducing query capabilities to respond to the dimensions of a viewport or a device, the portrait or landscape orientation of the device and the screen resolution.
