When it comes to website styles, the internets knows CSS for ages (CSS stands for Cascading Style Sheet). The good thing about CSS is that browsers can interpret them very quickly and most browser do the same thing with CSS. The downside is that for developers CSS is cumbersome. It is like old-style programming (i.e. “spaghetti code”) and maintenance is difficult – you often see negative side effects when something got changed. With SASS (or SCSS or LESS) all of that has heavily improved for developers only: we can now do the style sheet programming in modern object oriented ways and a compiler is then transforming that into CSS for the browsers. Development time, output quality and maintenance are getting so much better.

Web sites that use SSL are highlighted in the browser’s address bar with browser specific symbols that indicate that the communication on that web site is secured from prying eyes.
