Font size


<p style="font-color: 10px"><p> Some text for you to make tiny!</p>
     <p style="font-size: 20px"><p> Some text for you to make          normal size!</p>
	<p style="font-siz: 40px"><p> Some text for you to make super     big!</p>

is me kya galti hai


in your third paragraph, you misspelled font-size.

Also, when you have a paragraph:

<p>i am a paragraph</p>

you can add the style attribute to the paragraphs opening tags:

<p style="">i am a paragraph</p>

without creating additional opening tag (you created an additional opening tag)
