CSS Dropdown Menu Alignment

I am having trouble aligning this drop down menu I created. The drop down menu won't align with the main menu correctly. Please help me align it properly.

Here is my CSS:

li {
display:inline;
padding-left:30px;
padding-right:30px;
}
ul {
list-style: none;
text-align:center;
}
ul li {
display: inline-block;
}
ul li a {
color: 000000;
text-decoration: none;
font-size: 24px;
text-align:left;
}
ul li ul {
display: none;
position: absolute;
}
ul li:hover ul {
display:block;
background-color: transparent;
position:absolute;
text-align:center;
}
ul a:hover {

media queries, what am I doing wrong?

Hi, as you'll see I'm relatively new at this.

I've had a website built that I administer using a custom CMS.

To customise the pages beyond the basic controls (background, inline picture & text content) there is an 'Embed' box that allows me to place (for instance) additional images.

I am attempting to specify the positioning of these images depending on whether being view on a smartphone or not. Having originally positioned an image using css (in under a heading). I realised that this did not look good on a smartphone so looked into media queries.

Gantry framework dropdown menu issue PLEASE HELP!

Hello,
I have an issue with my menu on a Joomla site:

http://pucs.under-development.info/

When you hover over the menu item the sub menu is displayed, but if you scroll down (sometimes slowly) the sub menu disappears.

I'm using the latest Gantry framework.

Any ideas on why and how to fix it?

Thanks

Adding individual style/class to an individual h2

Hi Everyone

I know this is a very simple question and it may have been answered on the forum before, but I have tried searching but because i dont know exactly what I am searching for and could not find my answer.

What I want to do is make an h2 look different from other h2`s. I also would love and example of once I make the change in my stylesheet how exactly do i then use that on a page.

I hope this makes sense, sorry for being so clueless...

Thanks in advance
