Bootstrap 3 - media queries Tablet Breakpoints


I have created a website using Bootstrap 3 and media queries. This is my basic .css media query setup, using the mobile first approach.

/* Custom, iPhone Retina */ 
@media only screen and (min-width : 320px) {

}

/* Extra Small Devices, Phones */ 
@media only screen and (min-width : 480px) {

}

/* Small Devices, Tablets */
@media only screen and (min-width : 768px) {

}

/* Medium Devices, Desktops */
@media only screen and (min-width : 992px) {

}

/* Large Devices, Wide Screens */
@media only screen and (min-width : 1200px) {

}

In addition I have this meta set for Mobile viewport optimization in index.html: <meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no">

When rezizing my browsers chrome and firefox, all the breakpoints works as expected. For mobile, both portrait and landscape, the mobile version is showed. But while testing the web site on a Samsung Galaxy Tab and a Ipad, I only get the full scale site.

Could it be that I am using the wrong breakpoints for tablets? Or something else? I am confused.. due to the fact that it works on mobile and in the browser!

    I did more digging on your full site. I recreated your site locally and used a new version of bootstrap CSS, changing the break point to 767 px. I then changed the breakpoints in your custom CSS to 767 px. There was still an issue loading on iPads, the full site was still loading.

    Upon further research I noticed the CSS sheet that you are referencing on a CDN for "Bootstrap Gallery". The issue is with this file. This file mentions includes the media queries for bootstrap! After making the changed above and commenting out this file, the site loads in mobile form for iPads in Portrait.

    <!-- Bootstrap Gallery -->
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">

    Twitter bootstrap was intended to show the full screen site for Tablets. Note that small devices show the full menu while extra small devices show the mobile menu.

    The break point set for small screens is at 768px - the width of the iPad in portrait mode - so the iPad renders as small screen. TO have the iPad render as an extra small device in portrait mode (with the mobile menu), change the min-width to 767px for the small screen break point.

    I'm curious if this happens in both the portrait and landscape modes for the tablets you are testing or ONLY in the landscape mode.

    I would expect this to happen in Landscape mode with the standard Bootstrap settings as the width of an iPad is 1024x and the medium breakpoint for bootstrap is 992px. Note that the iPad falls into that Medium category and Medium shows the the full menu and not the mobile menu.

    If you want to change the breakpoints you can also do this by setting up a custom bootstrap instance. Change the medium break point to somewhere around 1030px: http://getbootstrap.com/customize/#media-queries-breakpoints.

    The issue here is that people on smaller laptops will get your mobile menu if they don't have your website in full screen.
