I want to change the width of a div\grid via a media query for desktop users, but can't get the style to apply.
Here is the div in Chrome dev tools:
So I want to set the width of my .ticketInforHeader div. I tried to do this, but it does not do anything:
#media screen and (min-width: 992px) {
.ticketInfoHeader {
width 30%;
}
}
Try using
#media screen and (min-width: 992px) {
.ticketInfoHeader {
width 30% !important;
}
}
I guess if you're using Bootstrap's grid the width of the columns will be defined by the already existing classes like .col-md-4
You might need to add an !important to overwrite the Bootstrap style
#media screen and (min-width: 992px) {
.ticketInfoHeader.col-md-4 {
width 30% !important;
}
}
but that doesn't look really good in the code and I feel it breaks the logic of using bootstrap's grid.

Working a lot now with CSS media queries, I wondered in which order it's best to use them.
Method 1
#media only screen and (min-width: 800px) {
#content { ... }
#sidebar { ... }
}
#media only screen and (max-width: 799px) {
#content { ... }
#sidebar { ... }
}
Like this obviously the code is shorter, but with a lot of CSS you end up having the CSS of one container spread to multiple places in your stylesheet.
Method 2
#media only screen and (min-width: 800px) {
#content { ... }
}
#media only screen and (max-width: 799px) {
#content { ... }
}
#media only screen and (min-width: 800px) {
#sidebar { ... }
}
#media only screen and (max-width: 799px) {
#sidebar { ... }
}
Like this if you specify the screen size (at which the CSS is active) for each container a new, the overview in my humble opinion is much better.
But with a lot of CSS you will use the #media query dozens and dozens times.
Does the second method cause significantly longer load time or has any other disadvantages?
EDIT:
I might have been not clear enough. My question doesn't really concern the order or the queries as such or about overwriting CSS declarations.
What I wonder about is rather the norms how other people include the media query "statments" into their css.
Lets say I have only one breaking point where I switch some CSS.
So I have one media query for min:800px and a second for max:799px.
Should I use both query "statements"
#media only screen and (min-width: 800px) { ... }
#media only sreen and (max-width: 799px) { ... }
only once in my whole stylesheet and include ALL the CSS for ALL containers into the two media query "statments"?
Or is it okay as well to use the media query "statments" mutiple times?
I mean instead of making two seperate areas in the stylesheet (one for CSS above and one for below 800px), if there are any concerns about the method of using the media query "statments" instead multiple times (for each part of the page again, like for Content, Widgets etc to make them responsive)?
I would just like to have the CSS for above and below 800px in two different parts of my stylesheet.
I know that ofc both methodes are working, I am jsut curious about the norms and if using the media query "statements" dozens or hundreds of times within a CSS sheet (instead of just twice in the case I jsut mentioned) will increase the loading times?
My answer on how you should use media queries can be applied to your question:
Here is how you should use media queries:
Remember use the sizes you like/need. This below is just for demo
purposes.
Non-Mobile First Method using max-width:
/*========== Non-Mobile First Method ==========*/
#media only screen and (max-width: 960px) {
/*your CSS Rules*/
}
#media only screen and (max-width: 768px) {
/*your CSS Rules*/
}
#media only screen and (max-width: 640px) {
/*your CSS Rules*/
}
#media only screen and (max-width: 480px) {
/*your CSS Rules*/
}
#media only screen and (max-width: 320px) {
/*your CSS Rules*/
}
Mobile First Method using min-width:
/*========== Mobile First Method ==========*/
#media only screen and (min-width: 320px) {
/*your CSS Rules*/
}
#media only screen and (min-width: 480px) {
/*your CSS Rules*/

#media only screen and (min-width: 640px) {
/*your CSS Rules*/
}
#media only screen and (min-width: 768px) {
/*your CSS Rules*/
}
#media only screen and (min-width: 960px) {
/*your CSS Rules*/
}
Here is a good tutorial from W3.org
Based on your edited question:
I guess this depends on each developer and how they need/think to develop his/her project.
Here is what I use to do ** (when not not using Pre-compliers)**:
I create a file styles.css which includes the general styles that will apply to the project like this:
/*========== All Screens ==========*/
{
/*General CSS Rules*/
}
Then having the media queries below, either using the non-mobile or mobile approach method explained above (in my case I usual use the non-mobile approach method).
But, depending on the projects you may need to have some other breaks besides the "standard" which can led you to use the rules in the way you mentioned.
Plus there are developers who prefer to separate into 2 files, the one with general styles CSS and other one with media queries styles.
Important: There is one difference from creating a file with general styles + 1 media queries (min-width:800px or max-width:799px), then only having a file with 2 media queries (min-width:800px/max-width:799px), which is when you have the general rules it will apply to ALL widths, therefore you just need to set the rules for 1 media queries.
Based on your last comment, the answer I could give you would be opinion-wised, so the best I can do for you is to give you a few articles so you can have your own opinion on this topic:
How many media queries is too many?

It means that, if you apply two rules that collide to the same elements, it will choose the last one that was declared, unless the first one has the !important marker
The second one will always display the content at 799px and whatever content has been styled as the style allocated for 799 rather than 800px if the device is 800px, in this case because it's 1px difference it doesn't make much different, but if you did it at around 200px different it would cause problems for your design.
Example:
if you have it this way:
#media (max-width: 800px) {
body {
background: red;
}
}
#media (max-width: 799px) {
body {
background: green;
}
}
The background would be green if the device is 799px in width or less.
if it was the other way round
#media (max-width: 799px) {
body {
background: red;
}
}
#media (max-width: 800px) {
body {
background: green;
}
}
if the device width was less than 799px the background would be green because no !important keyword has been defined.
when the !important keyword has been defined, result for example one will be the same
#media (max-width: 799px) {
body {
background: red; !important
}
}
#media (max-width: 800px) {
body {
background: green;
}
}
It won't take the processor longer unless the two elements collide. You'll be fine to vary min-width and max-width.
I suggest you to use the first method.
If you are developing a site mobile first then you won't need media queries for mobile but for tablet and desktop only.
//Mobile first
.your-mobile-styles-also-shared-with-tablet-and-desktop{
}
//Tablet
#media only screen and (min-width: 641px) {
#content { ... }
#sidebar { ... }
}
//Desktop
#media only screen and (min-width: 1025px) {
#content { ... }
#sidebar { ... }
}
If you are using a CSS pre-processor like SASS or LESS you can always create many LESS or SASS components that you will include in your main.less or main.scss / .sass file.
So each component will have not so many media queries and you can divide each component with some comments like shown above.
Your code this way will be easier to read and also much shorter, because all properties shared by tablet and desktop can be defined at the beginning of you CSS component file.
Look at this page
There are 3 images on the right. When I look at my site with a mobile device, those 3 images stay there instead of centering in the middle, and so they make the page overflow/have a left-right scroll.
Any ideas on how I can fix it so that the images get centered when the page is viewed on mobile?
Thank you
Use a CSS media Query
The code used in the example you gave is
#media (max-width: 600px)
.about-us-images {
width: 100% !important;
}
The #media (max-width: 600px) part is telling the page to only apply those styles when a page width is 600px or less.
Adjust it to Your Preferences
You can adjust that to any size you wish or use the reverse to style any page that is 600px or wider using: #media (min-width: 600px).
Try this—
#media (max-width:600px) {
.about-us-text,
.about-us-images { width:100% }
}
Just add a class to the images div, and change the breakpoint as you wish. Looks like this now—
Here is what I had to do.
#media (max-width:600px) {
.about-us-text {
float: none !important;
width:100% !important;
}
}
#media (max-width:600px) {
.about-us-images {
width: 100% !important;
}
}
That did it.
I want to get the screen width as a variable for a simple if statement. Basically if the screen is > 768 it will display the normal website. If it's < 768 than it displays a more compact version. It's just a little fix for ipad resolution. I already know how to update the webpage once i get the info, just how do I get the values in the first place?
use javascript..
there is a property called
.screenwidth()
here is a link:
http://www.w3schools.com/jsref/prop_screen_width.asp
You could use CSS media queries:
#media all and (max-width: 768px) {
body {
background: #ccc;
}
}

I am currently creating a responsive web design using media queries. For mobile devices I want to remove my JS slider and replace it with something else. I have looked at .remove() and a few other things from the JQuery library, however these have to be implemented into the HTML and I cannot think of a work around from the css angle.
Do you need to remove them, or just hide them? If just hiding is okay, then you can combine media queries with display:none:
#mySlider{
display: block;
}
#media (max-width: 640px)
{
#mySlider
{
display: none;
}
}
You can hide an element and show another depending on screen size using media query from css , this is from one of my live projects (I use this to show/hide icon)
#media only screen and (max-width: 767px) and (min-width: 480px)
{
.icon-12{ display:none; } // 12 px
.icon-9{ display:inline-block; } // 9px
}
Not a 100% sure what you mean. But I created a class "no-mobile" that I add to elements that should not be shown on mobile devices. In the media query I then set no-mobile to display: none;.
#media screen and (max-width: 480px) {
.nomobile {
display:none;
}
}
You can also use jquery function addClass() and removeClass() or removeAttr() to fulfill your purpose.
Example:
$(window).resize(function(){
if(window.innerWidth < 500) {
$("#slider").removeAttr("style");
}
});
Or you can also use media query as follow :
#mySlider{
display: block;
}
#media (max-width: 500px)
{
#mySlider
{
display: none;
}
}

I would like to know how to show something (say a div) on small screens only but not on large screens.
I've tried something like:
#media (max-width: 480px) {
.show-on-small-only{ display:block; visibility:visible;}
}
...
and anything larger has eg:
#media (max-width: 768px) {
.show-on-small-only{ display:hidden; visibility:none;}
}
it doesn't seem to work as intended.
might be worth pointing out that i'm using bootstrap 2.0
It's a better practice to make all your default style mobile-friendly and then use min- media queries to size up:
div { /*put whatever your default styles are first*/ }
/* Then use the media query to hide it at 481 and wider */
#media all and (min-width:481px) {
div { display:none }
}
Look at 320andup and Skeleton and the CSS of this page for examples. Look at the helper classes towards the bottom of this CSS for differences between invisible/hidden etc.
You can put this first
/* for small screens, only execute in if statement */
#media only screen and (min-width : 320px) and (max-width : 768px) {
.smallOnly {
visibility:visible!important;
display:block!important;
}}
Then at the bottom of it put it for large screens (always execute since not in if statement)
.smallOnly {
visibility: none;
display: none;}
The important tg makes it so that anything with important always overwrite everything else and it will be the master rule regardless of where it is in the file.
