CSS, or Cascading Style Sheets, is a programming language used to define the visual styling of
web pages. While HTML is used to define the structure and content of a web page, CSS is used to
control the layout, colors, fonts, and other visual elements of a page.
CSS works by defining rules, or styles, that apply to specific elements on a web page. These
styles are defined using selectors, which are used to target specific elements on a page, and
properties, which define the visual characteristics of those elements. For example, a CSS rule
might target all the headings on a page and set their font size and color.
CSS allows developers to create consistent, attractive designs for their web pages without
having to define the styling for each element individually. By creating reusable styles that can
be applied across multiple pages, developers can save time and ensure consistency across their
site.
In addition to its core styling features, CSS also provides support for responsive design, which
allows web pages to adapt to different screen sizes and device types. This is done through the
use of media queries, which allow developers to define different styles for different screen
sizes.
CSS is an essential skill for anyone looking to build modern, responsive web pages. By mastering
CSS, developers can create visually appealing, user-friendly web pages that look great on any
device.
