Gap appears in drop-down navigation only when page is scrolled - html

Question

I recently built my first website (with much trial and error) and was quite pleased until I noticed that when you scroll down the page a little it creates a gap in the navigation so you can't click on the dropdowns. I'm going crazy trying to fix it. Can anyone please help? The site is at: http://lamplighters.org/education/smw.html

Answer 1

it appears to be an position issue that is set witht the element on the css. It would help to see your html and css code.

Answer 2

I can tell you that it has to do with the fact you used position: fixed. You have a series of other problems with your CSS as well.

Answer 3

I inspeceted the page and found a lot of things that didn't come together well for the navigation. Good housekeeping is not in order.
#nav, #nav ul {/*By doing this you are setting these attributes to both the nav div and the nav ul*/
padding: 0;
margin: 0;
list-style: none;
line-height: 1;
text-align: center;
}
#nav, #nav ul {/*By doing this you are setting these attributes to both the nav div and the nav ul. This is redundant and should be consolodated into a single #nav, #nav ul, if you are going to use these assigned attributes. */
padding: 0;
margin: 0;
list-style: none;
display: inline-block;
}
ul {/*By doing this you are only targeting any ul on the page*/
list-style: none outside;
}
ul, ol {/*By doing this are targeting both ordered lists and unordered lists to have these attributes*/
margin-bottom: 20px;
}
ol, ul {/*By doing this are targeting both ordered lists and unordered lists to have these attributes*/
list-style: none;
}
#nav li {
float: left;
width: 137px;
text-transform: capitalize;
display: inherit;
position: relative;
}
li {
line-height: 18px;
margin-bottom: 12px;
}
You may want to wipe your nav css clean and start from scratch.
I pulled a css file and put it below. hope this helps. Good luck with your sytle sheets in the future.
