I'm curious if I can use CSS to target the first url syntax below if a user is below a certain screen width.
For example, if a user's browsers is below 700px, I do not want to show the first background image (background.png) - just the second (background1.jpg).
<div class="right-header" style="background-image: url('/wp-content/uploads/2020/11/background.png'), url('/wp-content/uploads/2020/11/background1.jpg');">
you can use media queries for that:
In your CSS file:
.right-header {
background-image: url('/wp-content/uploads/2020/11/background.jpg');
}
#media screen and (max-width: 700px) {
.right-header {
background-image: url('/wp-content/uploads/2020/11/background1.jpg');
}
}
And in your HTML:
<div class="right-header"></div>

Why does nothing I do on my CSS style sheet work?
I have the following code which displays a placeholder div when on a desktop screen and to disappear when it's displayed on a mobile/tablet screen.
#media only screen and (min-width: 940px) {
.image_placeholder {
display: block;
}
}
.image_placeholder {
display: none;
}
<div class="image_placeholder">
This is an image placeholder
</div>
Why can't I get this to work: Set the .image_placeholder with css todisplay:none; when the screen width is below 920px and set it to display:block; when it is at 920px or above.
Why does the .image_placeholder disappear regardless as to whether the screen is above or below the 920px threshold?
Assuming the missing . in front of the second image_placeholder isn't there in the actual code:
CSS rules, when selectors are of equal specificity, are applied in order.
So, if the media query applies:
.image_placeholder { display:block; }
.image_placeholder { display:none; }
So it gets none.
If the media query doesn't apply, then you just have:
.image_placeholder { display:none; }
So it gets none.
Order matters.
If you want the media query rules to override the non-media query rules then put the media query last.
You should write the media query after the main CSS.
.image_placeholder {
display: none;
}
#media only screen and (min-width: 940px) {
.image_placeholder {
display: block;
}
}
<div class="image_placeholder">
This is an image placeholder
</div>
Edit:
An example code with image would be like this -
.image_placeholder {
display: none;
}
#media only screen and (min-width: 940px) {
.image_placeholder {
display: block;
}
}
<div class="image_placeholder">
<img src="https://via.placeholder.com/500x500.jpg">
</div>
<p>This is sample text to test that the placeholder image div leaves no white space in mobile resolution.</p>
You should add full stop . in-front of class name like .image_placeholder.
I have a less file containing a simple css class that needs to have different styles applied for various screen sizes. The following code only works on desktop (the first #desktop media query). Nothing happens for mobile. I have tried many variations of this syntax with no luck and haven't found anything about this in the docs. You can also see the live demo here (notice how if you stretch the screen wider than 1024px the div turns orange, but it does not turn red or green when smaller than 1024px as it should). Thanks.
html
<div class="derp">
Hello
</div>
less
#desktop-min-width: 1024px;
#phone-max-width: 768px;
#desktop: ~"only screen and (min-width: #{desktop-min-width})";
#tablet: ~"only screen and (min-width: #{phone-max-width}) and (max-width: #{desktop-min-width}";
#phone: ~"only screen and (max-width: #{phone-max-width})";
#appHeight: 749px;
#appWidth: 421px;
.derp {
#media #desktop {
background-color: orange;
}
#media #tablet {
background-color: red;
}
#media #phone {
background-color: green;
}
}
There is a problem with
#tablet: ~"only screen and (min-width: #{phone-max-width}) and (max-width: #{desktop-min-width}";
Remove it for a moment, and you will see green background is displayed for phone screen.
You need to add ")" for a #tablet at the end
I've got a problem which I have no idea how to get around of.
I use a shop script where I can only edit CSS file.
I have a div with background-image and in there I have a normal image:
<style type="text/css">
.someclassforcss img{
some:attributes;
}
.someclassforcss {
background-image:url(/link.png);
}
</style>
<div class="someclassforcss">
<img src="/link2.png">
</div>
Everything's good, but I want to use media queries (or any other method) to hide background-image of div for mobile devices, but I have no idea how to make it, because media queries doesn't work for specific attributes, only for whole elements, so if I would've hided the div, my img is also hided which i don't want.
You DO can change attribute regarding media dimensions.
Your CSS:
.someclassforcss {
background-image:url(/link.png);
}
#media screen and (max-width: 762px){
.someclassforcss {
background-image: none;
}
}
Try this:
#media only screen and (max-width: 767px){
.someclassforcss {
background: none;
}
}
You can hide the div with a media query. eg:
#media (max-width: 600px) {
.someclassforcss {
display: none;
}
}
or if you just want to remove the background image:
#media (max-width: 600px) {
.someclassforcss {
background-url: none;
}
}
I need a media query (or similar) using pure CSS, HTML or possibly LESS (as long althogh pre-compiled won't work) to apply a particular class to an ID depending on the screen height. I'm setting classes defined by Add2Any - not css properties.
jsfiddle
What I want to do is set the div #add2any to this for small screens.
<div id="add2any" class="a2a_kit a2a_default_style">
Otherwise I want this:
<div id="add2any" class="a2a_kit a2a_kit_size_32 a2a_default_style">
Is this possible, and how?
Looking for a non-javascript/not Jquery solution to avoid time lag and having a <div> for each style and showing only the relevant one.
Background
The idea is to change the layout and size of the AddToAny bar for small screens, so instead of 32px images it displays a totally different style of compact bar, with less buttons, and using AddToAny's classes means future changes they make would not be dependent on fixed css in my stylesheets. Browser compatibility is important.
CSS so far
#media screen and (max-height: 430px) {
.a2a_button_google_plus, .a2a_button_pinterest, .a2a_button_print { display:none;}
#add2any a, hr#add2any, hr#add2any a, .a2a_divider { font-size: 15px; padding-top:2px; padding-bottom:-2px; }
.a2a_divider { top:5px ; position: relative}
}
Edit
Unable to find solution from any of these, I'm using foundation framework.

**Edit 2 **
Suggestions of using Less or Sass from this question seem like overkill, since the solution would be needed on every page.
Self-hosting the script and adding some javacript to it might be a better choice, the class names look certain to remain the same even if the script changes since all Customize instructions encourage direct use of AddToAny's class names.
Edited
If you have this html:
<div class="a2a_kit a2a_default_style">
<div class="a2a_kit a2a_kit_size_32 a2a_default_style">
You can make a media query like this:
/* first state */
.a2a_kit { display: block; }
.a2a_kit.a2a_kit_size_32 { display: none; }
#media screen and (max-height: 430px) {
/* reverse behaviour on max-height 430 px */
.a2a_kit { display: none; }
.a2a_kit.a2a_kit_size_32 { display: block; }
}
You just need to set up modified styles in your media queries:
#add2any {
/* any styles you want to apply all the time */
background-color: blue;
width: 100px;
color: white;
}
#media (min-width: 420px) and (max-width: 760px) {
/* styles when screen is greater than 420px wide but less than 760px */
/* omitting the 'and (max-width: 760px)' would cause these styles to apply at any width above 420px unless overridden by another media query */
#div1 {
background-color: red;
width: 300px;
color: yellow;
}
}
#media (min-width: 760px) {
/* styles when screen is greater than 760px wide */
#div1 {
background-color: green;
width: 600px;
}
}

Using the #media tag, how do I display a new image, for example I have a logo I want to use for my main site and a mobile logo for my mobile site, how to I display the smaller logo only on the mobile site using #media?
I've tied using "display:url('xxxx') but that hasn't seemed to work.
You'll have to put two logos on your HTML, like this:
<img src="" class="desktop-logo">
<img src="" class="mobile-logo">
Then, you'll have to hide the mobile-logo by default:
.mobile-logo {
display: none;
}
Then, on your media query, you'll have to hide the desktop-logo and show the mobile-logo:
#media screen and (max-width: 480px) {
.desktop-logo {
display: none;
}
.mobile-logo {
display: block;
}
}
What you'll want to do is create an element and set a background on it. You'll use #media control what the background image is based on the size of the window.
#media only screen and (min-width: 768px) {
.logo {
background: url('image.jpg');
}
}
#media only screen and (max-width: 767px) {
.logo {
background: url('imagesmall.jpg');
}
}
And this is what your element would look like.
<div class="logo"></div>
Create a tag with a class then use mediascreen to apply new styles to said class
create a div tag
css/
#media screen .... etc {
.image {background-image: url('wwww....');
}
So, when the exact pixels are reached at the screen it will apply a backround image to that image class I created above.
