Bootstrap 3 Apply different CSS on Mobile and computer - css

I am using a bootstrap 3, have an div element with class outer and want to apply different css on mobile and computer.
For example, this is my css codes:
/* for computer */
div.outer {
height: calc(100vh - 80px);
padding: 0;
margin: 0;
min-height: 500px
}
/* for mobile */
div.outer {
position: fixed;
top: 50px;
left: 0;
right: 0;
bottom: 0;
overflow: hidden;
padding: 0;
}
How do I implement it? Thanks for any suggestions.

Use media query for mobile devices. below is template, dont forgot to add mobile meta tag.
#media only screen
and (min-device-width: 320px)
and (max-device-width: 570px)
and (-webkit-min-device-pixel-ratio: 2) {
//your css for mobile is here
}

I would recommend using media queries for this one.
To change the div.outer class when in mobile use the code below.
/* Extra Small Devices, Phones */
#media only screen and (min-width : 480px) {
div.outer {
position: fixed;
top: 50px;
left: 0;
right: 0;
bottom: 0;
overflow: hidden;
padding: 0;
}
}
More media queries here

For mobile you have tp define width of the device in '#media' queries.
767px is a standard width of screen for mobile and tablets. So you can use like this
#media all and (max-width:768px){
// your css for mobile
}
This css will apply only when you device width will be 768px or less

Responsive #media-queries setup for template Blogger

Use default Blogger template, named Simple. That because let me edit more template. But responsive design is poor. Only on mobile small screen the text can be readable easy. I tried to add media-queries, but I'm not experience in CSS. Below you have code that I tried apply, but unsuccessfully.
EDIT:
We have succeeded add some code that works pretty well. I need your help to improve code already published by me, but also to add sidebar to adjust or may not display.
For sidebar, class was that: fauxcolumn.

Thanks a lot for any help!
Blogger has a responsive template called "Contempo" which has media queries already in place. You might want to give it a try. I am using it in my travel blog. The SEO is broken (like in most of the blogger templates), but I fixed those issues as well and you can get the fixes from my GitHub (sorry, no links, you have to dig them out by yourself as some "experts" here are editing posts removing all links).

CSS responsive vertical scrollbar issue

I'm currently playing with bootstraps v2.3.2. media querys (I'm not using bootstraps grid, just those 4 media queries) to test them on mobile and tablet devices, and I notice that I keep getting a horizontal scrollbar and I don't understand why?
Basically I have one div and this CSS:
html {
box-sizing: border-box;
}
*, *:before, *:after {
box-sizing: inherit;
}
body{
margin:0;
/* height: 3000px; */ /* forced vertical scrollbar */
height: 300px;
}
div{
padding: 0 10px;
margin: 0 auto;
background: aqua;
width: 980px;
border: 1px solid black;
height: 100%;
}
/* Large desktop */
#media (min-width: 1200px) {
div{
background: red;
width: 1200px;
}
}
/* Portrait tablet to landscape and desktop */
#media (min-width: 768px) and (max-width: 979px) {
div{
background: yellow;
width: 768px;
}
}
/* Landscape phone to portrait tablet */
#media (max-width: 767px) {
div{
background: blue;
width: 100%;
}
}
/* Landscape phones and down */
#media (max-width: 480px) {
div{
background: green;
}
}
Situation when I force vertical scrollbar: JSBin
But when I don't force vertical scrollbar, I get the wanted result: JSBin
So it's obviously due the vertical scrollbar. I found this article about scrollbar issue in Responsive Web Design, but I get the same result in both Chrome and FF.
Update: as looking the source of bootstrap v3.3.2 I've noticed that they have new media queries, however, they don't use the minimal possible width for the .container. This are their media queries:
#media (min-width: 768px) {
.container {
width: 750px; /* 18px difference */
}
}
#media (min-width: 992px) {
.container {
width: 970px; /* 22px difference */
}
}
#media (min-width: 1200px) {
.container {
width: 1170px; /* 30px difference */
}
}
And here's the JSBin. Even when I forced the vertical scrollbar to appear, this won't trigger the horizontal scrollbar.
But if I want to use the minimal possible width for the media queries, like:
#media (min-width: 768px) {
.container {
width: 768px;
}
}
#media (min-width: 992px) {
.container {
width: 992px;
}
}
#media (min-width: 1200px) {
.container {
width: 1200px;
}
}
This will trigger the horizontal scrollbar - JSBin
Did the guys from bootstrap did that on purpose, because of the possibly that there can be the presence of vertical scrollbar?
Question: Why can't I use the minimal possible width in the media query when the vertical scrollbar is present?
I know that this may be a novice question, but I would appreciate if someone clarify this for me.
Bootstrap Media Querys
Setting media query
Bootstrap supports four media sizes:
Phones < 768px (8 inch)
Tablets ≥ 768px
Desktops ≥ 992px (10.33 inch)
Desktops ≥ 1200px (12.5 inch)
These are not fixed sizes!
If you have a screen that has a min-width of 768px the media query should trigger.
However setting a container to 768px will almost allways make that screen overflow
First of all the body element of all modern browser does have a margin to it.
example: Webkit browsers: body {margin: 8px;} so if your element of 768px and a margin-top of 8 and margin-bottom of 8 you get: 784px
so your screen is 768px (or less) and your content is 784px this will make it overflow (as it should). That said bootstrap sets: body {margin:0;}
An other example would be border. Border adds size to your element unless box-sizing isn't default. While outline sets the border inside your element.
Did the guys from bootstrap did that on purpose, because of the possibily that there can be the presence of vertical scrollbar ?
There is a possibility of that but i would think they set it because there is a bunch of css property's that affect size, so they gave a margin of error so to speak to avoid strange behavior like a horizontal scroll bar popping up.
Question: Why can't I use the minimal possible width in the media query when the vertical scrollbar is present?
You can use it: Fiddle!
Just Remember that some browsers will render it with a certain width.

How to work with media queries?

Hello guys I am using the following code to show and hide some elements but it seems to doesn't work on mobile devices.
#media screen and (max-width: 768px) and (orientation : portrait) {
.drawer1 {
display: block;
top: 789px;
}
.drawer {
display: none;
}
.drawer1-content {
background: #fff;
background-repeat: no-repeat;
border-collapse: collapse;
height: 645px;
width: 100%;
}
}
#media screen and (min-width: 769px) {
.drawer {
bottom: 0px;
height: 700px;
overflow: hidden;
position: absolute;
width: 1024px;
z-index: 5;
}
.drawer1 {
display: block;
}
..from the code you posted, looks like you miss a } at the end..
Also check if your device has a width less than 768px in the first case
and it has a width more than 769px in the second case (landscape or portrait)
try one of the several extensions available on Chrome/Firefox/Opera to set the max width of the viewport and simulate a mobile device..
From the comment:
so from the specs: IPAD 3gen: 2048-by-1536 pixel....here you have your answer :D just change the max-width and min-width ..or just use the landscape and portrait attributes

HTML5 Video not getting hidden in media query

Similar problem was posted but the answers there did not help me.
I have a responsive web site in which the whole background is a mp4 format video. On desktop browsers there is no problem. The code for that is below
#media screen and (min-width: 400px)
{
video {
position: fixed; right: 0; bottom: 0;
min-width: 100%; min-height: 100%;
width: auto; height: auto; z-index: -100;
background-size: cover;
}
}
And the media query for small screens is below
#media only screen and (max-width : 400px) {
background: url(../images/tanisalimmobilebackground.jpg);
background-size:cover;
video {
display:none!important;
}
}
The problem is when I view it on iOS Chrome and Safari the video is not hidden and is on the background with controls shown and not started.
What i want to do is if the width is at a max of 400 px , I want to show the jpg that is mentioned above.
I think you need to specify the element that should have the background. E.g:
#media only screen and (max-width : 400px) {
someelement{
background: url(../images/tanisalimmobilebackground.jpg);
background-size:cover;
}
video {
display:none!important;
}
}

I can't get my mobile version of site exactly centered

I'm having some odd space issues on the left of my site. For some reason there is slightly more space on the left than on the right in mobile view, thus looking off-centered. I'm guessing its off for desktop view as well, but its not noticeable. I can't figure out what is making it this way. http://jeffreydowellphotography.com/
/* ---------->>> MOBILE gap/space issues <<<-----------*/
#media screen and (max-width: 400px) {
#pageWrapper { margin: 0;}
.sqs-layout .sqs-row .sqs-block:last-child {
padding-bottom: 0;
padding-top: 0;
}}
/* ---------->>> MOBILE center logo <<<-----------*/
#media only screen and (max-width: 400px) {
h1.logo {
text-align:center;
margin-bottom: 20px !important;
}}
/* ---------->>> MOBILE logo size <<<-----------*/
#media only screen and (max-width: 400px) {
.logo-image .logo img {
max-height: 110px;
margin: 5px;
width: auto;
}
.social-links {
padding-top: 20px;
}}
Try removing the margin: 5px; on .logo-image .logo img in your mobile styles. The image with the margin may be wider than the div that contains the image and it comes off as being non-centered.
UPDATE
I took a look at your site, its actually the margin on the .slide selector. Add this in your mobile styles:
.slide { margin: 0; }
