ABSTRACT
Cascading style sheet (CSS), or simply style sheets, supply a way to specify presentation styles independently and associate them with markup elements in webpages. A webpage consists of two basic parts: Hypertext Markup Language 5 code and CSS code. As CSS became popular and sophisticated, the World Wide Web Consortium decided, in 2001, to divide CSS into specification modules to make it more manageable. Because most style properties set for the body element apply to the entire page through inheritance, CSS makes whole-page styling easy to enforce. The CSS3 border-radius property defines the curvature of the rounded corner. Given a layout grid, CSS is used to implement the design. There are two common approaches to implement a layout grid: using floating columns and using CSS table display. The CSS properties min-width and max-width set the minimum and maximum for width of an element to help the browser adjust the element when the browser window is resized.
