Description of problem

Hello, everyone.

After editing the forum header, the layout seemed no problem for me, as administrator and a PC user.
After publishing the changes, forum members who use cellphones or tablets, notified me that the look was wrong.
Somehow, the site is all to left for those using cellphones and tablets.
As shown in the attached image, i ask for help to correct any error that i has committed.

These were the scripts that I modified:

Code:

#logos1 {
line-height: 160% !important;
background-image: url('http://i.imgur.com/vCVDBHB.png') !important;
background-repeat: repeat-x;
}

ul#nav{
line-height: 20px !important;
padding-left: 51% !important;
padding-right: 50% !important;
margin-right: -50% !important;
}

#nav {
position: relative !important;
left: -30% !important;
background-image: url('http://i.imgur.com/vCVDBHB.png') !important;
background-repeat: repeat-x !important;
width: 720px !important;
}

#pun-logo {
left: 10% !important;
position: relative !important;
}

#logos1 {
    background: url('http://i.imgur.com/rMk70TE.png');
    height: 120x;
    line-height: 120px;
}

.logos2 {
    width: 1024px;
    margin: 0 auto;
}

#pun-logo {
    margin-top: 40px;
}

#pun-logo img {
    -webkit-transition-duration: 1s;
    -moz-transition-duration: 1s;
    -o-transition-duration: 1s;
    transition-duration: 1s;
    background-repeat: no-repeat;
}

ul#nav li.menuitem {
float: left !important;
margin-right: 10px !important;
list-style: none !important;
margin-top: none !important;
margin-bottom: none !important;
}

ul#nav li a {
color: #fff !important;
text-decoration: none !important;
padding-left: 20px !important;
text-shadow: 0 1px #666 !important;
}

I noticed this is causing some horizontal overflow ( scrollbar ) :

Code:

ul#nav{
line-height: 20px !important;
padding-left: 51% !important;
padding-right: 50% !important;
margin-right: -50% !important;
}

If you're attempting to center these elements, I'd recommend using text-align center.


Basically, apply text-align center to your logo container :

Code:

.logos2 { text-align:center; }

Remove everything except line-height :

Code:

ul#nav{
line-height: 20px !important;
padding-left: 51% !important;
padding-right: 50% !important;
margin-right: -50% !important;
}

Remove position, left, and width from this :

Code:

#nav {
position: relative !important;
left: -30% !important;
background-image: url('http://i.imgur.com/vCVDBHB.png') !important;
background-repeat: repeat-x !important;
width: 720px !important;
}

remove this :

Code:

#pun-logo {
left: 10% !important;
position: relative !important;
}

Replace this :

Code:

ul#nav li.menuitem {
float: left !important;
margin-right: 10px !important;
list-style: none !important;
margin-top: none !important;
margin-bottom: none !important;
}

By this :

Code:

ul#nav li.menuitem {
display:inline-block;
margin-right: 10px !important;
list-style: none !important;
margin-top: none !important;
margin-bottom: none !important;
}

Fantastic work, @Ange Tuteur.
Could you please fix these areas to fit the same which you fixed? (?)

The background colors did not follow the same width.
