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!
2.The tag for listing

<li>133.My street</li>

</ol>
