I try to switch the display mode via javascript.
Assuming i have the html element with a class "display_mobile" i tried:
#media only screen and (max-width: 767px), html.display_mobile {
/* mobile mode definitions */
}
but this does not works.
Any idea how to solve this?
Like this. Media queries do not allow to use selectors in condition.
#media only screen and (max-width: 767px) {
html.display_mobile .any-definition {}
}

I feel like this should be easier for me to solve but for some reason I can't get it to work right.
I would like the Navigation to be fixed at the top on mobile. What am I missing?

You just need to modify this rule
#media only screen and (max-width: 768px) {
#header {
position:fixed; /** Change to fixed **/
}
}
currently it is set to relative on mobile

simple question.
I'd like to set the css property of a class, say the container's padding-top, to different values depending if I am on a xs device or on a sm device.
Any suggestions?
Sorry for the basic question.
You can use CSS media queries. Bootstrap includes media queries for specific device "breakpoints" (http://getbootstrap.com/css/#grid-media-queries) so you would override like this..
/* Small devices (tablets, 768px and up) */
#media (min-width: 768px) {
.container {
padding-top:20px;
}
}
/* Medium devices (desktops, 992px and up) */
#media (min-width: 992px) {
.container {
padding-top:40px;
}
}

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.
I have the following less code:
#mobile: ~'screen and (max-width: 480px)';
Then I use it as follows:
#media #mobile {
// some code
}
It works fine but I would like to also use "not" like:
#media not #mobile {
// some code
}
But I get the error
ParseError: Unrecognised input
in the "not" part.
Is it possible to solve this?
Maybe you could do something like this:
Define the width of a mobile device:
#mobileWidth: 480px;
Then anything larger is a non-mobile device:
#notmobileWidth: #mobileWidth + 1px;
Create LESS variables for both mobile and notmobile:
#mobile: ~'screen and (max-width: #{mobileWidth})';
#notmobile: ~'screen and (min-width: #{notmobileWidth})';
And then use those in your media queries:
#media #mobile {
// some mobile code
}
#media #notmobile {
// some not-mobile code
}
I'm trying to make the move to being a Responsive developer (instead of a fixed one). I've been trying to understand media queries as of late and having some confusion. The test is simple:
I want to change the body background color to red for mobile, yellow for tablets, green for wide screens. The following code demonstrates this (for the most part). The issue I'm having is when the width drops below 480px (30em's), the background reverts back to its default css (background turns red to white). Now.., my small mind tells me "ohh I'll just make a
#media only screen and (min-width:1em) { body { background:red;} }
... that will fix the problem!"
This however seems wrong and unintuitive. Does anyone know the proper way to achieve this simple task?
/*
==========================================================================
MOBILE (min-width 480px)
========================================================================== */
#media only screen and (min-width: 30em) {
body { background:red; font-size:.75em; }
}
/*
==========================================================================
TABLETS (min-width 768px)
========================================================================== */
#media only screen and (min-width: 48em) {
body { background:yellow; font-size:.85em; }
}
/*
==========================================================================
SCREENS (min-width 1140px)
========================================================================== */
#media only screen and (min-width: 71.25em) {
body { background:green; font-size:1em; }
}
If I were you, I'll revert the whole CSS into a max-width. Something like max-width: XX is a smartphone, max-width: YY is a tablet, else is a screen. So, it'll turn into something like this:
body { background:green; font-size:1em; }
#media only screen and (max-width: 71.25em) {
body { background:yellow; font-size:.85em; }
}
#media only screen and (max-width: 48em) {
body { background:red; font-size:.75em; }
}
