Cascading Style Sheets, fondly referred to as CSS, is a simply designed language intended to simplify the process of making web pages presentable. CSS is like the makeup of the web. It helps websites look more put-together and aesthetically pleasing. It's what makes the text the right color, the background the right shade, and the buttons the right size. But, that's not all it can do! CSS can also bring websites to life with its animation property.
