CSS Images
This helps in adding an image to a website. CSS can handle images like JPG, PNG or other raster format. There are two types images: plain images which are sometimes referenced with a url, and dynamically generated images which are generated by some element.
Code Sample
<img src="picture.jpg" alt="Picture" width="100" height="100">
- src: It consists of the value of the path to the required image
- alt: If the image is not displayed then an alternate text can be displayed using alt attribute.
- width: This specifies a width for the image(can be percent or px or auto)
- height: This specifies a height for the image(can be percent or px or auto)
CSS Defaults
The img element will be rendered by default in most browsers to be displayed as an inline-block display type unless specified otherwise.
img {
display: inline-block;
}
More Information:
It is advised to change any one parameter, either height or width, to get a proportionate image. Changing both dimensions results in forced scaling and is not advisable.

Image Sprites
An image sprite is a collection of images put into a single image. A web page with many images can take a long time to load and generates multiple server requests. Using image sprites will reduce the number of server requests and save bandwidth.
