CSS is the abbreviation for Cascading Style Sheets and stands for cascading style sheets. It is languagewhich is used to describe the form of web pages. It consists of a list of rules which, when written down appropriately, are interpreted by the browser, which displays the elements in the manner described. It can be said that the appearance of web pages and more is due to CSS. Why was CSS developed? It allows flexible formatting management elements found in electronic documents. CSS also aimed to separate the content aspect of a page from the way it is presented. Cascading style sheets have appeared since the HTML 4 - earlier versions did not allow material to be handled at an advanced level. CSS allows you to give appropriate properties to all the tags in a document. The language was developed by the W3C (World Wide Web Consortium), a standard-setting organisation for writing and transmitting web pages, which was founded in 1994 by Tim Berners-Lee.
