Well, now that you know what CSS (Cascading Style Sheets) is from my last post. CSS is as a stylesheet language, used to describe the presentation of web pages written in HTML (or XHTML). The main purpose of CSS is to separate the presentation of a web page from its content, allowing for greater flexibility and control over the design and layout of the page.

CSS allows web designers and developers to define the visual style of a web page, such as the colors, fonts, layouts or any other number of visual elements. This separation of presentation from content also makes it easier to maintain and update the appearance of a website, as changes to the CSS code can be applied globally to all pages that reference it.

Responsive Web Design

CSS also enables the creation of responsive web design, which allows web pages to adapt to different screen sizes and devices, improving the user experience on mobile and tablet devices. It can also improve the accessibility of web pages by providing semantic markup for screen readers and other assistive technologies.

In summary, the purpose of CSS is to provide a powerful and flexible way to control the presentation and layout of web pages, while separating the design from the content to improve maintainability and accessibility. Pretty cool huh?
