Hi,
I get your idea but this need heavy customization. It not only requires changes in CSS but also the layout of mainbody block. In CSS, you may need to add something like:
@media (min-width: 980px) and (max-width: 1199px){
.container,
.navbar-static-top .container,
.navbar-fixed-top .container,
.navbar-fixed-bottom
.container{ width: 100%; }
}
then in mainbody block – ‘mainbody.php’ file and change:
<section class="container t3-mainbody" id="t3-mainbody">
<div class="row">
to
<section class="container t3-mainbody" id="t3-mainbody">
<div class="row-fluid">
However, the most complicated thing is that I have no idea of how to apply this change in layout for Ipad Landscape only.
I recommend you to hire a good developer to get this done for you.
Regards
