I am doing a project using the new updated Bootstrap 3 RC1.
There are may new features with the new Bootstrap 3 which are much different than the previous versions.
I figured most of the changes but one I can't resolve:
when the menu has many items it breaks in Ipad and other tablets becuase it doesnt get collapsed like it automatically collapsed on mobile (which is good)
I would like to know how do I "force" ipads to act like mobile and show a collapsed menu or better yet - how to collapse the menu if it has many items and on certain screens and smaller it breaks
here are screenshots of my live project:
-- Menu on Big Screens --
-- Menu on Ipad Landscape --
-- Menu on Ipad Portrait --
-- Menu on Mobile --
I simply want the ipad to act like mobile. notice that the portrait does act like mobile as far as the content but not the menu.
Please read: http://bassjobsen.weblogs.fm/twitter-bootstrap-3-breakpoints-and-grid/
The collapsing of your menu is defined in the less files. (Download the latest version from:https://github.com/twbs/bootstrap )
In variables.less you will find #grid-float-breakpoint: #screen-tablet; where #screen-tablet is 768px.
So by default your menu will collapse when the screen width is below the 768px;
The ipad landscape has a screen width of 1024px so the menu will NOT collapse. The ipad portrait screen width is 768 px so the menu will NOT collapse.
See also navbar.less:
// Responsive navbar
// --------------------------------------------------
#media screen and (min-width: #grid-float-breakpoint) {
To change this behavior you have to change the #grid-float-breakpoint b.e set to 767 and recompile your css files.
NB You also mentioned: "notice that the portrait does act like mobile as far as the content but not the menu."
You use "col-lg-" as prefix for your grid rows. "col-lg-" elements will stack below the 992px (ipad portrait) and become horizontal above 992px (ipad landscape).
Just ran into this issue as well. I suggest you visit:
Bootstrap customization
Find the field #grid-float-breakpoint and set it to the screen width after which menu should collapse. There you could use variables from previous section, namely from Media queries breakpoints to set proper points.
Also, take a moment and check through all available variables to change. Creating a well-customized Bootstrap package might save you hours of dev. work, if not more.
For those poor souls who are not using less, you would have to modify the bootstrap.css and change media queries associated with navbar that have a breakpoint of 768px to 992 px.
For example, change
#media (min-width: 768px) {
.nav-tabs.nav-justified > li {
display: table-cell;
width: 1%;
}
.nav-tabs.nav-justified > li > a {
margin-bottom: 0;
}
}
to:
#media (min-width: 992px) {
.nav-tabs.nav-justified > li {
display: table-cell;
width: 1%;
}
.nav-tabs.nav-justified > li > a {
margin-bottom: 0;
}
}
The no less implementations I found didnt work
Couldn't find the styles to make this happen on its own anywhere, ended up finding this - https://coderwall.com/p/wpjw4w
I was able to correct our issue by changing the #media (max-width: 768px) query to 767px instead. One of the links above referenced a 1px issue on iPad which breaks differently and was forcing the mobile version of the website instead.
If anyone is using the standard bootstrap.css file, I had to change it in 3 places:
around line 3780
/*changed from 768 to 992 */
#media (min-width: 992px) {
.navbar-header {
float: left;
}
}
around line 3799
/* changed from 768 to 992 */
#media (min-width: 992px) {
around line 3924
/*changed from 768 to 992 */
#media (min-width: 992px) {
I hope this helps someone :)
I had the opposite problem. On iPad the navbar was not collapsed (as expected), but the styles for a collapsed navbar were applied. I got it solved by changing the media query for the collapsed navbar adding -1 to match with $grid-float-breakpoint as follows:
#media (max-width: $screen-sm-min - 1) {
//styles for collapsed navbar (which won't show up on iPad portrait)
}

I have to write a custom media query in portrait and landscape for Samsung A20 and I can't find the viewport. Does anyone know this? (not for A20s or A20e).
Thanks
You can change the min and max width according to your requirement here
#media only screen and (min-width: 200px) and (max-width: 414px) and (orientation : portrait) {
//Put your CSS here for 200px to 414px width devices (cover all mobile portrait width //
}
#media only screen and (min-width: 500px) and (max-width: 767px) and (orientation:landscape) {
//Put your CSS here for 500px to 7674px width devices (cover all mobile landscape width //
}
You can query for the current device viewport size:
window.innerWidth
window.innerHeight
Well, in short, if you will target every single mobile device out there, you would be nearly mad. So, my suggestion as a Front-End Developer is that you should always go for main break points and never forget to start from "max-width" in media query.... Max width will help you to target from 0 to 396px or 396px to 768px. But min-width will allow from 396px to 0.
So max-width is best option
and
Go for main break points for mobile devices
Media queries for A20 portrait:
#media only screen and (min-device-width: 320px) and (max-device-height: 694px)
(I'm not absolutely sure about WebKit but you can try 2.2)
and (-webkit-device-pixel-ratio: 2.2)
I'm using the standard bootstrap 3 media queries that use max-width, but also want to include some for smaller phones and tablets, but can't figure out how to get them both to work for their respective devices.
For example I know this will handle any most phones:
#media (max-width:767px)
But if I want to have a separate queries for say, iphone 5's like this
#media only screen and (min-device-width : 320px) and (max-device-width : 568px)
Either one or the other will work.
I've tried changing the order (as I know the later one will override the earlier one) and adding "!important" declarations, but nothing seems to work.
Int this particular instance I have series of links with a button below them and need to have the padding between them be smaller so they will all fit on a smaller screens (in this example an iPhone 5, but I'd like to have a 3rd one for iPhone 4 etc.), but not be to close together on the bigger one.
Is there an easy way to do this?
Thanks in advance for any help you can be.
Here's a rough example of what I tried for 3 different sizes.
/iPhone 4 and other small phones/
#media only screen and (min-device-width: 320px) and (max-device-width: 480px){
.topic-link h5 {
padding-bottom:12px;
}
}
/iPhone 5 and other medium phones/
#media only screen and (min-device-width: 320px) and (max-device-width: 568px){
.topic-link h5 {
padding-bottom:18px;
}
}
/iPhone 6 and other large phones/
#media (max-width:767px){
.topic-link h5 {
padding-bottom:24px;
}
}
Here's attempt number 2:
/iPhone 4 and other small phones/
#media only screen and (min-width: 320px)and (max-width: 480px) {
/iPhone 5 and other medium phones/
#media only screen and (min-width: 320px) and (max-width: 568px) {
/iPhone 6 and other large phones/
#media only screen and (min-width: 375px) and (max-width: 667px) {
I would suggest either being more specific with your rules (for example your min-device-width for iPhone 5 could be larger than the previous max and so on.), or using min-width in the manner suggested by this answer. Perhaps give this a read as well in regards to using min-width vs min-device-width.
I am experiencing elements transition misbehaviour into my page, IE(11) only;
The fullscreen revolution slider, remain in place doesn't move with the wrapper when the left slider is opening (clicking on info+ button like we have in Chrome/Firefox). Thanks to #afelixj, I've tried to use this css hack for IE in order to apply the tansition effect to the fullscreen slider too, adding .fullscreen-container but without result.
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
.header, #bar-left, .fullscreen-container{
left: 0;
transition: all .5s;
}
.shiftnav-open .header, .shiftnav-open #bar-left, .shiftnav-open .fullscreen-container{
left:590px;
}
}
For comparation, please open this page in IE11 and Chrome and open/close the left slider using the info+ button.Live link here
Other non fullscreen rev sliders pages work fine using the left slider open/close in IE11/Chrome.
live link here.
Any thoughts?
LE: also I've tried to aaply to the #wrapper or .shiftnav-wrapper:
#media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
#wrapper{
left: 0;
transition: all .5s;
}
.shiftnav-open #wrapper{
left:590px;
}
}
(In this second test, the result looks ok in fullscreen rev slider pages but if I open a non-fullscreen rev slider page, the content will be shifted with +590px over 590px. when the left slider is open).
Instead of the .fullscreen-container, can you try to apply the style to .forcefullwidth_wrapper_tp_banner class?
I'm using Bootstrap 3 and trying to remove/exclude the breakpoint between medium and large devices. I have a existing website which is optimised to 970px which looks great. What I am trying to do is remove the md > lg breakpoint so that even on large widescreen desktops the maximum body width is 970px and still centred.
Anyone know if there is a quickfix solution to this?
Any advice would be much appreciated

If you're overriding the bootstrap breakpoint (and using containers properly), adding this below the bootstrap breakpoint media queries in the bootstrap CSS file should work for you.
If using LESS
#media (min-width: #screen-lg) {
.container {
width: 970px;
}
}
OR, you can simply override the bootstrap container in your own CSS (just make sure you load it after bootstrap.css)
#media (min-width: 970px) and (max-width: 2500px) {
.container {
width: 970px;
}
}
OR you can find the media query in the bootstrap.css file on around line 1240 and simply change it there
#media (min-width: 1200px) {
.container {
width: 1170px; /* change 1170 to 970 */
}
}
the less way is good but this one is more flexible and reliable:
#media (min-width: #screen-sm) { .container { width:#screen-md; } }
Because in bootstraps default values the width of #screen-md is 992px.
Now you will just have a breakpoint for small devices (smartphones) and any other bigger devices. they will all get the same layout
You can set a max width on the containers:
.container-fluid,
.container {
// Disable large-desktop breakpoint.
max-width: $container-md;
}
No need for media queries or anything.
The $container-md value is typically 970px, unless you changed the $grid-gutter-width. For LESS, replace the $ of variables with an #. For regular CSS, replace the variable with the hard coded pixel size.
The nav starts out great once you lower the bowser width the nav becomes stacked, this is great. Once you open the window back up the nav items are in two rows. Here's a pic.
This is how it starts out:

FWIW, I found that forcing a redraw of the .nav-justified element in question helps WebKit understand. Obviously, how you chose to do this is up to you—I opted for the fadeIn(), 'cause when life hands you lemons...
$(window).bind('resize', function(){
var w = $(this).width(),
threshold = 768;
if(w < threshold){
$('.nav-justified').hide().fadeIn();
}
});
Both answers seem to be lacking. The JS solution causes a lot of flicker, and the CSS solution doesn't seem to keep the integrity of the designed tabs. Here's what I came up with.
If you're not using less with your bootstrap styles just replace #screen-sm with 768px
#media (min-width: #screen-sm) {
.nav-tabs.nav-justified > li {
display: block;
float: left;
width: 32.9999%
}
}
The problem is display: table-cell; instruction in the .nav-justified class.
Let's take a look at the bootstrap.css file, I believed that you are using Bootstrap version 3.0, at line 4109.
#media (min-width: 768px) {
.nav-tabs.nav-justified > li {
display: table-cell;
width: 1%;
}
You must change it to :
#media (min-width: 768px) {
.nav-tabs.nav-justified > li {
display: inline-block;
float: left;
margin-left: 100px;
}
}
This will solve your problem.
This is a known bug with Bootstrap.
This has been fixed in Chrome Since 2013, but is still an open bug in WebKit and occurs in Safari.
Safari exhibits a bug in which resizing your browser horizontally causes rendering errors in the justified nav that are cleared upon refreshing. This bug is also shown in the justified nav example.

I recommend to not use .nav-justified or be ok with it not working properly in Safari.
