The Low Down

Similar to the <img> element, the height, width, src, and alt attributes define the height, width, source and alterative text of the image button.

• The height and width attributes are only relevant on <img> and image buttons, <input type="image">, defining the size of the image:
  • The height attribute defines the height of theimage in CSS pixels. The width attribute defines the width.
  • If omitted, and not defined with CSS, the height and width of the image will be the actual size of the image.
• The src attribute defines the source or location of the image.
• The required alt attribute provides alternative text in case your image doesn’t show up and for users who can’t otherwise “see” your image.
