You could adjust when the responsive code kicks in for the iPads around line 3893 –
/* iPads (portrait)
--------------------------------------------- */
@media only screen and (max-width: 1023px) {
Change the above number to around 1080 and see if that fixes it.
But when I do that, the sidebar section will be placed below the main section.
Right now it is below the title, but the menu is slightly to the right, and I have a member menu item that will display when members are logged in, and when this is displayed the menu is even more to the right.
Can any suggest how I center the menu below the title on the iPad when viewed in landscape mode?
