1 ：The img tag 

   img tag allows put some img file into page. just like :

<a href = "me.png">
    <img
        src = "me.png"
        width = "50%"
     />
</a>

  And the  " src = "me.png" " lets brows knows where the img in computer.The " width = 50% "tells that the img's width is whole page's with 50%.

And if zoom the page u would find the img's size change too! But if u set like " width = 150px ".It will not!
