Images

You can control the size of an image using the width and height properties in CSS, just like you can for any other box.

Centering images Using css

By default, images are inline elements. This means that they flow within the surrounding text. In order to center an image, it should be turned into a block�level element using the display property with a value of block

Background Images

The background-image property allows you to place an image behind any HTML element. This could be the entire page or just part of the page. By default, a background image will repeat to fill the entire box.

Repeating imges repeat The background image is repeated both horizontally and vertically (the default way it is shown if the background�repeat property isn't used).

background-position

When an image is not being repeated, you can use the background-position property to specify where in the browser window the background image should be placed.

Using CSS, it is possible to create a link or button that changes to a second style when a user moves their mouse over itknown as a rollover and a third style when they click on it.

Contrast of background images

If you want to overlay text on a background image, the image must be low contrast in order for the text to be legible.

  • High Contrast A high contrast background image makes the text difficult to read.

  • Low Contrast A low contrast background image makes the text easier to read

  • Screen A screen added to a high contrast image makes the text easier to read.
