-### Introduction
+### 소개
HTML, or HyperText Markup Language, is the 'skeleton' of the web. If CSS 'dresses up' your HTML and JavaScript brings it to life, HTML is the body of your web application. HTML's syntax even reflects that idea, as it includes "head", "body", and "footer" tags.
In this lesson, we're going to use HTML to layout the 'skeleton' of our virtual terrarium's interface. It will have a title and three columns: a right and a left column where the draggable plants live, and a center area that will be the actual glass-looking terrarium. By the end of this lesson, you will be able to see the plants in the columns, but the interface will look a little strange; don't worry, in the next section you will add CSS styles to the interface to make it look better.

On your computer, create a folder called 'terrarium' and inside it, a file called 'index.html'. You can do this in Visual Studio Code after you create your terrarium folder by opening a new VS Code window, clicking 'open folder', and navigating to your new folder.

### HTML Tags
In HTML, you add tags to your .html file to create elements of a web page. Each tag usually has an opening and closing tag, like this: `
hello
` to indicate a paragraph. Create your interface's body by adding a set of `` tags inside the `` tag pair; your markup now looks like this:
