Hello!

I want to adjust (align) the content (body) of my Joomla site as it's shown on the images attached to this question. There're picture 1 and picture 2. I want it to be like on a picture 1. Basically, I want to decrease spacing above the top horizontal main menu.

You going to need to supply us with your html/css so that we can see where you going wrong?

 

Or maybe a link to the site for us to take a look.

Hello!

You're right. It's just I host my site at home and my server is not always on. But I'll do my best to keep it online for a time being, so my site would be accessible.

I think it's better than a homepage, since the homepage right now is just empty from content.
What I did is this (someone gave me a hint). The big spacing above my upper horizontal main menu was due to some "gkToolbar", which is probably unnecessary from what I was told.
I edited template.css of my current template like so:

#gkToolbar {
 
   display: none;
}
body {
    margin: 0 !important;
 
    /* color: #6C6459;
    height: 25px;
    margin: 20px 0 0;
    overflow: hidden;
    padding: 10px 0 0; */
}

After this adjustment, I had 10px spacing above and below upper horizontal main menu. The lower space I found out myself how to change. It's by changing this code of the same file as above:

#gkMenuWrap {
    margin-bottom: 5px;
}

But I still don't know how to change (lessen) the upper space (10px).

I've got J 2.5 and MyStore template. All the relevant files I can attach here if needed. But I'll do my best to keep the site going.
Thanks!

You have 5px margin top on the element

#gkMenu

I've said this many times, but using IDs in your CSS is asking for trouble.

Thanks a lot!
