CSS IMAGES

We use CSS to control the size and alignment of images.

Size: We use the width and height properties.
Alignment: We use the float property.
Centering: Images are inline elements by default. We display with the value block.
Background Images: There are a few properties we can use:
- background-image Places image behind any html element.
- background-repeat Image is repeated horizontally or vertically.
- background-attachment Specifies if image should stay in position or move as the user scrolls.
- background-position Specifies where in the browser window should be placed.
- background Shorthand for all the other background properties.
Rollover: Changes buttons to a second style when user moves the mouse over it.

HTML Video & Audio

The html elements for embedding these type of media documents are <audio> and <video>. There are many ways to utilize them within an html file. It is now convention to use third party hosting services like youTube or Vimeo for this purpose. It allows us to free storage from our site.
