In the above example we are selecting everything within the body tag. Listed above are some the changes you can make as far as backgrounds go. Most of them need to further explanation. In fact, a lot of CSS is easy to look out and learn, it just requires exposure. "Background-Attachment" tells the browser wether or not to move the background with scrolls. In the second line of code I am selecting just the "p" tags, and adding some CSS in a much more compact form. It's a little harder to read, but handy once you become better at CSS.
In the next example we are going to work with text a bit. Just like in the other example most of this doesn't need further explanation. Try not to confuse the "text" and "font" selectors. See the below code snippets:
The "font" selector allows us to quickly and easily change font size, type and style in a number of ways.
We have only begun to scratch the surface. CSS is easy to learn, and there are so many different things you can do with it! I hope you continue your learning and expose yourself to some new tags.
