TLDR
CSS stands for “Cascading Style Sheets” It is a formatting language that allows us to visually improve our HTML tags (size, color, font, etc.) As the name suggests, it does it by cascading. The advantage of using an external.css file is that our HTML page will be easier to read and manage. Our biggest priority should always be to have a re-readable code. When working with a team of developers, you want the rest of the team to understand the code so they can make necessary changes.via the TL;DR App
