# HTML Demo

HTML tags are the basis of all web applications. They give the page structure, and define the content within.

An HTML tag takes the following form:

```html
<tag class="foo" onclick="myFunction()" otherAttributes="values"> </tag>
```

HTML tags can also be nested to create a tree that we call the [Document Object Model](https://developer.mozilla.org/en-US/docs/Web/API/Document_Object_Model/Introduction)

```html
<div class="my-page">
  <h1>My Page</h1>
  <ul class="link">
    <li><a href="https://github.com/Microsoft/frontend-bootcamp"> Frontend Bootcamp </a></li>
    <li><a href="https://twitter.com/micahgodbolt"> @micahgodbolt </a></li>
    <li><a href="https://twitter.com/kenneth_chau"> @kenneth_chau</a></li>
  </ul>
</div>
```
