The height property is used to set the height 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.
You can try to run the following code to set the height of an image −
<html> <head> </head> <body> <img style = "border:2px solid green; height:100px;" src="/css/images/logo.png" /> <br /> <img style="border:2px solid green; height:50%;" src="/css/images/logo.png" /> </body> </html>
