hello, i'm writing an article that needs to be 2-column, with abstract at the top going across both columns, labeled sections with the content of 'materials' and 'methods' in a smaller font size, and citations in the bottom of each page rather than all at the end. most of those elements i have already, but how do i specify a smaller font size for certain sections? and how do i get the citations to appear on each page as they show up in the text? <br>
<br>any suggestions would be greatly appreciated! thank you,<br>sara<br>
