CSS
CSS stands for Cascading Style Sheets. CSS is a style sheet that can be used in HTML to deeply modify your page. CSS is widely used and is very helpful with its various amounts of available customization. Some examples are border, color, and size. With every CSS you must add {, put the commands after, then and end with }.Here is what it should look like:
#example{
border: 2 px solid red;
}
Putting a # will be an id which should only be used only once. Putting a . will be a class which can be used for multiple tags.
