# CSS Intro & File Set Up

CSS Controls how HTML elements appear on the page and save time by allowing you to make  and store formatting designs on document that can be re-used for several websites.

CSS Style Sheets do NOT contain any content - they only contain formatting information 

Create a new document in your notepad 

```
This block is evidence of all the mistakes that Mrs. Wright made
```

ave this file  as `style1.css` in the HTML folder on your desktop

**Selector**: Which tag are we developing the formatting for. In the example - we are indicated that every time we use `<h1>`, the  font will be blue and size 12.&#x20;

Each formatting declaration is separated by a `;`

First you indicated which formatting property you want to set and then after the `:` you provide the value

```
p  {
    color: red;
    text-align: center;
    }
```
