Improving and new features to my page

HTML & CSS

I am designing a little tool to identify organisms and is online here:

ID Tool Link

I have some features in mind which I need some assistance. The page is php / mysql. Maybe first we discuss if the page can be improved.

I don’t know if I should put the php or html code here apart the css?
