Why the font size of this page appears different.
In the bullet list text are bigger than body text. I coud not figure out.
Did you copy and paste the text into the page or did you simply write them in? If you copied and pasted the text then you will need to remove the formating from them to allow them to get the default setting of your browser.
You have the font-size set to 16px in your CSS as seen here:
Change it to 12px.
