CSS stands for Cascading Style Sheets, and it is the language used to style the visual presentation of webpages. It is a powerful tool for web designers and developers, as it allows them to easily control the look and feel of their sites. With CSS, you can control the color, font, size, layout, and other aspects of webpages.
CSS plays a vital role in helping websites look great. Without it, websites would be very plain and difficult to navigate. It also helps ensure that websites are optimized for different devices (such as phones and tablets). In short, CSS makes your website easier to use and more visually appealing.
CSS consists of a set of code rules that are used to define how HTML elements (such as titles, paragraphs, images) should be displayed on a webpage. For example, you can use CSS to change the background color of a page or make text appear bold. By using CSS rules appropriately, you can create beautiful websites that look great on all devices.
