What does CSS stand for in web development?

CSS stands for Cascading Style Sheets. It is a stylesheet language used to control the appearance and presentation of web pages. Therefore, Option B (Cascading Style Sheets) is the correct answer.

CSS is commonly used together with HTML and JavaScript to build websites. HTML provides the structure and content of a webpage, while CSS controls how that content looks. CSS can be used to define colors, fonts, spacing, borders, backgrounds, layouts, and many other visual properties.

For example, CSS can change the background color of a webpage, adjust the size and style of headings, create navigation layouts, and make a website responsive so that it works properly on different screen sizes.

The word "Cascading" refers to the way CSS rules are applied when multiple style rules affect the same element. CSS supports different ways of applying styles, including inline CSS, internal CSS, and external CSS.
