CSS menu conversion

CSS menu conversion
website (http://freetutorials.name)

On my website, I added onpage dropdown menus because of the size of
page content
I put them in java script onpage (not external)
Now I want to convert the java script to external css
An example of the java script menu is on "mechanical engineering"
The feeble attempt I made is on "HTML Editors"
The header image is repeating and the dropdown.
I have two external css - one for page styling and one for menus
I think they may be conflicting, but don't know.
Any suggestions on how to correct. I would like to keep one css
for page styling and the other for menus
This way, in the future, if I need to change something, I go to
the correct css.
Thank You for your time and information

note: the external css is on the following post.
one for page layout and one for menus
