### HTML
HTML stands for "HyperText Markup Language". It is the language used to write text in webpages.
### Tags
A tag is a word between angle brackets, like `<p>` or `<div>`. Tags are the basic building blocks of HTML. Most tags have an opening tag, and a closing tag, with some text in between.
`<tag>Some text</tag>`
Tags can be nested, like this:
`<tag1><tag2>Some text</tag2></tag1>`
Some tags do not need to be closed, for example `<img>` and `<br>`.
HTML documents are made up of many tags, nested inside of one another.
### Attributes
Tags can also have attributes, which are added in the opening tag. Attributes are used to specify additional information about the tag.
`<tag attribute1="value1" attribute2="value2">Some text</tag>`
Attributes are used differently on different tags, and each tag can take different attributes.
