how to alter image size in css code example

Example 1: resize image html

<!--
Resize image using html 

When we add any image in 'src' attribute of 'img' tag then image appears with original size on webpage
and if we want to resize the image we have to add extra attribute i.e. height and width to img tag to resize the image

Simple img tag
<img src="image_path" alt="Image Sample">

With height and width attribute
<img src="image_path" width="200" height="40" alt="Image Sample">
