How to apply style only for mobile device? - javascript

I'am creating new web site. My intention is creating one page for desktop and mobile and set styles depend of device (mobile or desktop). I know I can achieve everything with pure javascript, but I would like to use also CSS and media queries. My question is: how can I set style only for mobile devices using CSS media queries? I was trying to use:
#media only screen{
style...
}
But it works for both, mobile and dekstop browsers.

You can not simply target mobile but have to give break point in order for it to work. You will have to use min-width or max-width for that to work
/* Smartphones (portrait and landscape) ----------- */
#media only screen and (min-device-width : 320px) and (max-device-width : 480px) {
/* Styles */
}
/* Smartphones (landscape) ----------- */
#media only screen and (min-width : 321px) {
/* Styles */
}
/* Smartphones (portrait) ----------- */
#media only screen and (max-width : 320px) {
/* Styles */
}
Example: This will hide div with class of sidebar and set container width to 100% on smaller screens
#media only screen and (max-width : 321px) {
.sidebar {
display:none;
}
.container{
width:100%;
}
}

Have you tried setting your styles based on screen-size rather than device?

If the styling, and even content, is entirely different from mobile to desktop, using a framework like Bootstrap makes this really easy. You can follow their strategy by creating hidden-xs and visible-xs classes with your own media queries, and apply those classes to different divs. Not the DRYest way of doing it, but gets the job done.
#media only screen
and (min-device-width: 375px)
and (max-device-width: 667px)
and (-webkit-min-device-pixel-ratio: 2)
and (orientation: portrait) {
.hidden-xs {
display: none;
}
.visible-xs {
display: block;
}
}

How do I scale an entire webpage for tablet screen width on load with javascript?

I have a webpage that is 1800x1200px in dimension (made for desktop PCs). On tablets the page isn't viewed entirely, part of it spans over the right viewport. What I want to achieve is that the webpage displays correctly on tablets using a smaller zoomfactor. I'm absolute beginner with javascript, can anyone explain the js code to me to do that?
Try adding this in the <head> section
<meta name="viewport" content="width=device-width, initial-scale=1.0">
Also you might have to use CSS media queries. If you are not familiar with that, Its better to learn it first.
For the time being, use the below media queries in your css
#media (min-width:320px) { /* smartphones, iPhone, portrait 480x320 phones */ }
#media (min-width:481px) { /* portrait e-readers (Nook/Kindle), smaller tablets # 600 or # 640 wide. */ }
#media (min-width:641px) { /* portrait tablets, portrait iPad, landscape e-readers, landscape 800x480 or 854x480 phones */ }
#media (min-width:961px) { /* tablet, landscape iPad, lo-res laptops ands desktops */ }
#media (min-width:1025px) { /* big landscape tablets, laptops, and desktops */ }
#media (min-width:1281px) { /* hi-res laptops and desktops */ }
Sample usage
/* Use a media query to add a breakpoint at 768px: */
#media screen and (min-width: 768px and max-width: 1023px) {
.main{
width: 80%; /* The main class's width is 80% , when the viewport is gretaer than 768px or smaller than 1023px which is ideal for tablets (not big tablets) */
}
}
You can use media queries for achieving this behaviour, example as follows -
#media only screen and (max-width: 600px) {
body {
background-color: lightblue;
}
}
This will apply a background color when the screen size will be 600px or smaller.
The best answer i can give right now is to use css zoom
body{zoom:30%}
body:after{content:"lol"}

Bootstrap navigation collapse on large screen

I have checked many sites using bootstrap menu, it collapse after certain screen size , I am using 22 inch screen and navbar collapse when I see my website..
You have to use media query for your screen size in terms of pixels.
For example:
// Landscape phones and below
#media (max-width: 480px) { ... }
// Landscape phone to portrait tablet
#media (max-width: 768px) { ... }
// Portrait tablet to landscape and desktop
#media (min-width: 768px) and (max-width: 980px) { ... }
// Large desktop
#media (min-width: 1200px) { .. }
Bootstrap menu can be resized for almost many kind of screens like mobile, tablet, ipad, laptop, desktop etc. But some resolutions may have missed out in their media query. For ex: as you told " I am using 22 inch screen ".. your desktop's max-width may not have listed in their inbuilt media query.
So, what I suggest is it is better to write your own media query for that types of cases.
For example,
#media (max-width: 1080px) { ... }
#media (max-width: 1440px) { ... }

CSS media query for exact viewport width

Using javascript I create a meta viewport and assign to it a value of 980px. The script is this:
var viewPortTag=document.createElement('meta');
viewPortTag.id="viewport";
viewPortTag.name = "viewport";
viewPortTag.content = "width=980, user-scalable=1";
document.getElementsByTagName('head')[0].appendChild(viewPortTag);
In CSS, is it possible to write a media query that fires only when the viewport width is EXACTLY 980px?
Yes, in CSS it is possible to use #media rules to target an exact width.
CSS Example
#media (width: 980px) {
/* Your CSS */
}
This is telling the browser, when the viewport width is exactly 980px wide, apply the following CSS. When your viewport width changes to 981px or 979px or anything that isn't 980px wide, the CSS will be removed.
Unlike the other answers, this is not using max-width or min-width because the #media rules allow you to just define width, which will target the exact measurement you give it. The width is defined using the viewport width.
Note: You can learn more about the CSS3 #media rule from W3 Schools. Specifically if you look under Media Features, you'll see the available variables, including width all the way at the bottom.
You could do something like this. The media query will be triggered at 980px width and would work for width no greater than 980px.
#media screen and (min-width: 980px) and (max-width: 980px) {
html {background-color: red !important;}
}
html {background-color: green; min-height: 300px;}
You can use the exact width like this:
#media screen and (width: 980px) {
/* CSS rules here */
}
using both width and height exactly for ipad pro width:1024px, height:1366px
#media only screen and (min-width: 1024px) and (max-width: 1025px) and (min-height: 1366px) and (max-height: 1367px)
#media screen and (min-width: 980px) {
body {
background-color: lightblue;
}
}

how to target landscape mode in different mobile phones

I'm trying to remove a javascript event only to mobile phones which are in landscape mode. I've tried using CSS media queries unsuccessfully, but I could not find a correct answer to this.
As an example, how to cover a code which detects landscape mode for at least iphone4 and Samsung Galaxy 3? Both are mobile devices but have different dimensions.
Is there a media query solution to target only landscape mobile devices?
Is there a javascript solution to target only landscape mobile devices?
/* Smartphones (portrait and landscape) ----------- */
#media only screen
and (min-device-width : 320px)
and (max-device-width : 480px) {
/* Styles */
}
/* Smartphones (landscape) ----------- */
#media only screen
and (min-width : 321px) {
/* Styles */
}
/* Smartphones (portrait) ----------- */
#media only screen
and (max-width : 320px) {
/* Styles */
}

Webpage Fitting To Every Screen Reslution

I Use This Code To Automatically Detect Users Screen Resolution And Redirect To Another Page
<script>
if (screen.width==1367 && screen.height==768)
{
window.location="http://www.yoursite.com"
}
</script>
But For Every Screen Resolution I Cant Edit The Site.
Is It Possible That I Just Make Single Page That Can Automatic Fit To Screen.
Thank-You IN Advance.
You could use CSS3 media queries rather than javascript to detect the device and load the page accordingly.
#media only screen and (max-width: 999px) {
/* rules that only apply for canvases narrower than 1000px */
}
#media only screen and (device-width: 768px) and (orientation: landscape) {
/* rules for iPad in landscape orientation */
}
#media only screen and (min-device-width: 320px) and (max-device-width: 480px) {
/* iPhone, Android rules here */
}
You would also need to add the meta port view tag as below:
<meta name="viewport" content="initial-scale=1.0">
You can use media queries and specify different stylesheets for different screens.
https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Media_queries
for example
<style>
#media (max-width: 600px) {
.facet_sidebar {
display: none;
}
}
</style>
For examples of already put up websites see: http://mediaqueri.es/
'defau1t' is write. Also you can set it by css like=> "width:100%"; you can check http://www.w3schools.com/js/js_window.asp too. Everything depends on your requirements.
