Styling with CSS
CSS is used to make our SVG elements look nice. It stands for 'Cascading Style Sheets' and it is a style sheet language used for describing the look and formatting of a document written in a markup language.
CSS (Cascading Style Sheets) allows you to apply a graphical design to your app.
Using CSS you can define the size of every element inside your SVG code.
Override app positioning to have more control over the app's behavior.
