Change image position depending on screen resolution - html

I have recently been learning about responsive web design. What I am trying to achieve is presented on the images below, one is for how the website should look like on desktop, and the other one is for mobiles devices.
So as you can see, there are four boxes. After clicking the box, in the textbox you will see some text referring to that box. What I have been thinking about is how to deal with this layout. Is it just the Media Queries and different CSS styling depending on the screen resolution? Or should i somehow (jquery?) switch the elements order in the DOM? Im not sure how to handle this. Thanks for any advice!

To expand on #D.Fraga's comment, the css #media rule could be used as follows:
#media screen and (min-width: 480px)
/* css for large device */
/* */
}
#media screen and (max-width: 480px) {
/* css for small device */
/* */
}
You have 2 sets of css, one for rendering larger devices, the other for smaller.
You may also considering using javascript screen.width with some sort of framework (i.e. angularjs) to dynamically render DOM elements based on screen size (though I highly recommend the former).

This can be solved with css only:
#media (max-width: 420px){
/* Your Code */
}
Study #media of CSS

If you use these media queries for different screen views, maybe your problem will be solved.
Media query for large devices like laptops, desktops with screen size 1025px to 1280px
#media (min-width: 1025px) and (max-width: 1280px) {
//Your css here
}
Media query for tablets, mobile (Landscape Layout) with screen size 481px to 767px
#media (min-width: 481px) and (max-width: 767px) {
//Your css here
}
Media query for smartphone mobile (Portrait Layout) with screen size 320px to 479px
#media (min-width: 320px) and (max-width: 480px) {
// Your css here
}

How to use min-width and max-width in CSS media queries with high density mobile device screens

I am doing my first steps in repsonsive design world.
I found out that the most recommended way is to use min-width and max-width to find out the size of the display area, like this:
#media (max-width: 1200px) { ... } /* for desktops */
#media (max-width: 991px) { ... } /* for laptops */
#media (min-width: 768px) and (max-width: 990px) { ... } /* for large tablets */
#media (max-width: 768px) { ... } /* for smaller tablets */
#media (max-width: 500px) { ... } /* for cellphones */
The problem is that newer phones have high density screens. My phone has width of 980px. Therefore it loads wrong CSS which is meant for larger screens.
I tried out max-device-width. It takes into account logical pixels and my phone width is 393 of those. It worked. But max-device-width is deprecated so i don't want to use it.
I found some examples of min-resolution and max-resolution as well.
It is also possible to use JavaScript to determine if the browser is mobile browser, but it doesn't seem to be the correct approach.
So I got kind of confused. Please give me hints what and how should I use to determine if the site is running on a mobile device and how to load the correct CSS for it. How it has to be done in correct and reliable way?
Thank you in advance.
first at all, the way you use it, wouldnt work well. For example:
#media (max-width: 1200px) { ... } /* for desktops */
#media (max-width: 991px) { ... } /* for laptops */
if a screen has the width of 900px, then both media queries would apply. Because 900px is below 1200px and below 991px. For that specific case your media queries should be as follow:
/* for desktops */
#media only screen
and (min-width: 1367px) {
...
}
/* for laptops */
#media only screen
and (min-width: 991px)
and (max-width: 1366px) {
...
}
/* for large tablets */
#media only screen
and (min-width: 769px)
and (max-width: 990px) {
...
}
/* for smaller tablets */
#media only screen
and (min-width: 481px)
and (max-width: 768px) {
...
}
/* for cellphones */
#media only screen
and (max-width: 480px) {
...
}
as you noticed, it should contain min and max width unless its the lwoer or top end (desktop and smartphones) the smallest smartphone size is 320px btw.
Also I changed the media queries to screen only, its just good practise as you want to address screens only.
Screen size:
Notice the difference between Hardware pixels and viewport Pixels. your phone might have something above 900 hardware pixels but onyl half or a quarter of it as viewport pixels.
Hardware pixels are the pixels that a device has physically and viewport pixels the pixels which can bea dressed by css.
The reason is, that the ahdrware pixels are not actually adressable is for sharpness. besides, it owuld be nearly unreadably otehrwise.
Edit: The cheap laptops screen panels have a resolution of 1366 x 768px. so the laptop width should be also set to 1366px.
There is a difference between device pixels and CSS pixels. On many screens they are treated the same, but on high DPI screens there can be several device pixels per CSS pixel. See this page on MDN for more reading.
To control the width in CSS pixels, use the viewport meta tag in your HTML. This tag is generally only interpreted on mobile devices so it shouldn't affect your site on desktop browsers. It specifies the minimum width at which your site will be displayed.
For example, to set your site to display at a minimum width of 500px on mobile, use:
<meta name="viewport" content="width=500, initial-scale=1">
To display the site at the browser's width use:
<meta name="viewport" content="width=device-width">
In addition to the MDN article, the following article may be helpful for setting display widths for tablets.
For responsive design, it's recommended to use Mobile First approach. You start with styling the mobile version and change it while the viewport grows.
With the following media queries you have different problems:
#media (max-width: 1200px) { ... } /* for desktops */
#media (max-width: 991px) { ... } /* will match laptops and desktop because your screen with is underr 991 but also under 1200px */
#media (min-width: 768px) and (max-width: 990px) { ... } /* for large tablets */
#media (max-width: 768px) { ... }
#media (max-width: 500px) { ... }
the correct approach should be
// you start with mobile version
#media (min-width: 500px) { ... } // will match only screen width >= 500px
#media (max-width: 768px) { ... } // will match only screen width >= 768px
#media (min-width: 768px) and (max-width: 990px) { ... } // will match only screen width >= 768px and < 900px (could be tablets also)
#media (min-width: 991px) { ... } // match also ipad on landscape mode
#media (min-width: 1200px) { ... } /* for desktops */

I want my web page to scale down only on Desktop & tablet but not on mobile devices

So my website looks great on Desktops having a display resolution of 1920x1080 or higher. It's an e-commerce website so I am having a lot of elements on product pages.
The problem is when viewed on Desktop or Tablets with resolution 1366X768 or less, a lot of these elements doesn't show up so users have to scroll down the page to view those elements. I fear that some users may not even notice these elements and I will potentially lose customers.
So, I thought why not scale down the webpage to around 75% so that all of the elements fit without scrolling and with little googling around I found this CSS code.
#media screen and (max-width: 1366px) and (max-height: 768px) {
html {
zoom: 0.75
}
}
Now it runs great on desktops and tablets and I loved how my webpages just scale down to 75% with all the necessary elements on the screen right in front of the user without requiring them to scroll down the webpage.
But I noticed a huge problem with it when I opened my webpage on mobile. Those were also scaled down to 75% of their original dimensions. I don't want them to scale down on mobile. I need them as is. Any ideas how I can achieve this?
You can do like this. Its work for ipad to laptop screens. its target the browser screens.
#media screen and (min-width: 768px) and (max-width: 1366px) {
html {
zoom: 0.75
}
}
Or you can use this code. max-device-width is the width of the device's entire rendering area. same as height
#media screen and (max-device-width: 1366px) and (max-device-height: 768px)
{
html {
zoom: 0.75
}
}
You should use device width/height instead:
#media screen and (max-device-width: 1366px) and (max-device-height: 768px) {
html {
zoom: 0.75
}
}
This should suffice, zooms in for any screen above 768px in width(ipad and above):
#media screen and (min-width: 768px){
html {
zoom:0.75;
}
}

bootstrap responsive issue in 2 specific points

This is my bootstrap website: http://www.feather.com.lk/index.php
My main issue is in iPad portrait view. The elements are not resizing as intended. However, further investigation into the issue showed that I only have this issue when the browser size is scaled down to 768px and 769px. I'm not sure how to solve this issue.
The media queries I used:
#media screen and (min-width: 0px) and (max-width:769px)
#media screen and (min-width: 770px) and (max-width: 992px)
#media screen and (min-width: 993px) and (max-width: 1199px)
#media screen and (min-width: 1200px)
It seems like there is a mismatch between your media queries and the ones provided by Bootstrap.
/* Extra small devices (phones, less than 768px) */
/* No media query since this is the default in Bootstrap */
/* Small devices (tablets, 768px and up) */
#media (min-width: #screen-sm-min) { ... }
/* Medium devices (desktops, 992px and up) */
#media (min-width: #screen-md-min) { ... }
/* Large devices (large desktops, 1200px and up) */
#media (min-width: #screen-lg-min) { ... }
(Bootstrap Media Queries)
As you can see here, the smallest Bootstrap media query takes a maximum width of 767px (notice that the next one starts from 768px). However, the smallest media query that you have used takes the width of up to 769px. That must be the reason why there are two pixels, where the website doesn't look as intended.
Try changing your media queries to be the same as the ones in Bootstrap.

bootstrap Media Query not working

With twitter bootstrap i applied
#media only screen and (min-width : 768px){
}
but this media query is working on all other width values too, such as 992px & 1200px.
Any solution?
1)Please check whether you have included the meta tag in the head section of your HTML document as
<meta name="viewport" content="width=device-width, initial-scale=1.0">
If this line is not present then none of your media query would work.
2) If you override bootstrap break points in your style sheet make sure your stylesheet is linked to your application properly.
3)understanding how min-width and max-width works will help you. If you are trying some wrong combinations, results may be weird :)
#media (min-width:480px) {}
The styles inside this media query would apply only if your viewport is minimum 480px or wider than that.
#media (max-width:767px){}
The styles inside this media query would apply to your viewport only upto 767px. For any resolution higher than 767px our styles won't be applied.
#media screen
This tells that this particular styles are only applicable to screen and not for print,projection or handheld. So #media screen or #media only screen wouldn't harm your media queries much.
These are some of my tips to troubleshoot media queries. Hope this would help you resolve your issue.
Change media Query to
#media screen and (min-width: 768px) and (max-width: 900px) {
}
Or any size between you want.
For more Details Refer This link.
You can use max-width. when screen regulation is maximum 992px, then it will work.
#media only screen and (max-width : 992px){
/*your styles for Tab device*/
}
You can use max-width. when screen regulation is maximum 767px, then it will work.
#media only screen and (max-width : 767px){
/*your styles for mobile device*/
}
Got it working now.
Mobile with max only then parts from to and above 1200 is reading default.
#media (max-width: 640px) {
}
#media (min-width:640px) and (max-width: 768px) {
}
#media (min-width: 768px) and (max-width:992px){
}
#media (min-width: 992px) and (max-width:1200px) {
}
i hope this may work for you
Please Define it in your style.css not in bootstrap
#media (min-width:768px)
{
}

What do you recommended should be the widths I should use for a responsive layout?
/* Default Width: */
.container { width: 940px; margin: 0 auto; }
/* Smaller than standard 960 (devices and browsers) */
#media only screen and (max-width: 959px) {}
/* Tablet Portrait size to standard 960 (devices and browsers) */
#media only screen and (min-width: 768px) and (max-width: 959px) {}
/* All Mobile Sizes (devices and browser) */
#media only screen and (max-width: 767px) {}
/* Mobile Landscape Size to Tablet Portrait (devices and browsers) */
#media only screen and (min-width: 480px) and (max-width: 767px) {}
/* Mobile Portrait Size to Mobile Landscape Size (devices and browsers) */
#media only screen and (max-width: 479px) {}
I've started using "320 and up"'s widths which are as follows:
Note that they go from small to large not the other way around though. This is more in line with progressive enhancement and definitely preferred anyway:
Brad Frost - mobile-first responsive web design
stuffandnonsense.co.uk - 320 and Up
// Default styling here
// Little larger screen
#media only screen and (min-width: 480px) {
}
// Pads and larger phones
#media only screen and (min-width: 600px) {
}
// Larger pads
#media only screen and (min-width: 768px) {
}
// Horizontal pads and laptops
#media only screen and (min-width: 992px) {
}
// Really large screens
#media only screen and (min-width: 1382px) {
}
// 2X size (iPhone 4 etc)
#media only screen and
(-webkit-min-device-pixel-ratio: 1.5), only screen and
(-o-min-device-pixel-ratio: 3/2), only screen and
(min-device-pixel-ratio: 1.5) {
}
If you use Sass, here's a little trick I've been using:
$laptop-size: "only screen and (min-width: 768px)";
$desktop-size: "only screen and (min-width: 1382px)";
// etc
And then
#media #{$laptop-size} {
// Styling here...
}
This way you can easily change widths in one place also you don't have to write the whole thing every time.
There is no recommended width for responsive layout. It's totally depends upon your layout structure. Layout Structure means use MEDIAQUERIES when you want any specific changes on an specific width or when your layout broke any specific screen width.
If you are looking for best/common practices and particular widths applied when using responsive layouts, I'd suggest you look into grid systems readily available. A quick google search yields a lot of results, but one of my favourite ones would be the 1140 grid from cssgrid.net (site no longer available) - I very much agree with their logic on choosing the measurements. Verbatim:
The 1140 grid fits perfectly into a 1280 monitor. On smaller monitors
it becomes fluid and adapts to the width of the browser.
Scrap 1024! Design once at 1140 for 1280, and with very little extra
work, it will adapt itself to work on just about any monitor, even
mobile.
