The width property is used to set the width of an image. This property can have a value in length or in %. While giving value in %, it applies it in respect of the box in which an image is available.
Example
You can try to run the following code to set the width of an image:
<html> <head> </head> <body> <img style = "border:2px solid green; width:100px;" src = "/css/images/logo.png" /> <br /> <img style = "border:2px solid green; width:50%;" src = "/css/images/logo.png" /> </body> </html>
