CSS, or Cascading Style Sheets, is a programming language widely used in web development to determine the design and formatting of electronic pages. CSS is one of the three main pillars of web technologies, along with HTML and JavaScript, as it focuses on determining how the content contained in a web page is displayed.
The use of CSS allows developers to comprehensively control the visual appearance of the page, since they can select colors, fonts, structures, page layout. CSS is based on the concept of inheritance and serialization in formatting, since properties that are applied to a particular element can be inherited or influenced by the rules in force elsewhere.
With the concept of seamless formatting, developers can reuse rules and apply them to multiple elements of a website. In addition, with recent developments in CSS, such as Flexbox and Grid, developers are able to easily create more complex and flexible layouts.
CSS is one of the key elements in improving the user experience across the web, as it can make sites more attractive and responsive to different user needs. With its power to define design and formatting, CSS remains a vital tool in the modern web development world.
