The step says that, create a media query for screens smaller than 800px in width. In that media query, create a #gallery img rule and set the width property to 50%. This will convert your gallery to a two-column layout. Based on the instruction I wrote the code as shown below but the error shows "You should add a new #media query". So how can I fix this problem?
#media (max-width: 800px){
#gallery img{
width: 50%;
}
}
I am not clear about what you want. But the width (and height) media features can be used as ranges, prefixed with min- or max- to indicate that the given value is a minimum or a maximum. For example:
#media screen and (max-width: 800px){
#gallery img{
width: 50%;
}
}

How to use min-width or max-height for panel elements in a responsive theme (in my case Zircon for Drupal 7 is used https://www.drupal.org/project/zircon)? When min-width is used, elements overlap when resized for mobile phones. max-height tends not to be usable. Could you indicate where to change css to make it work for both cases or the one with min-width?
For example, in page.css for adaptive panel elements some classes are used (pane1 and pane2). In total there are 3 panes. The third pane works fine and moves down but pane1 and pane 2 start to overlap each other.
in page.css (Zircon theme):
pane1{ min-width: 300px; }
pane2{ min-width: 300px; }
pane3{ min-width: 300px; }
Use media queries. For example:
CSS:
#media all and (max-width: 500px) {
pane1{
min-width: 200px;
}
}
This code will apply only when browser width is smaller (or equal) than 500px.
I don't know if I clearly understood you, but I hope this will work.
Media queries would be your answer:
#media screen and (min-width: 767px){
.pane1, .pane2, .pane3{
min-width:300px;
}
}
#media screen and (max-width:766px){
.pane1, .pane2, .pane3{
min-width:150px;
}
}
Want to know correct (the best) way how to write (code) css for different window widths.
Here is live example https://jsfiddle.net/q0ony7Lb/16/
For example, have left, right sidebars and main content (#middle).
<div id="left">Content in left div<br/></div>
<div id="middle">Content in middle div<br/></div>
<div id="right">Content in right div<br/></div>
If widow width is less or equal to 400px, then want to show only #middle.
If width more than 400px and less than or equals to 700px, then display #middle and #left.
If width more than 700px, then display all.
At the moment doing in such way:
1) write default css (as understand "default" css applies if no other rules inside corresponding #media screen). Default css like
#left {background-color:#fff; background-repeat:repeat; background-position:left top; width:180px; height:25px; font-size:16px; font-family:Verdana; color:black; border-style:solid; border-width:1px; border-color:#000; text-align:left; padding:0px 0px 0px 0px; }
2) For certain window width write special css rules. Like
#media screen and (max-width: 400px) {
#left, #right { display:none}
#middle { width:350px; height:75px; }
}
#media screen and (min-width: 401px) and (max-width: 700px) {
#right { display:none}
}
As result, for example, if window width is less or equals to 400px then hide both sidebars and #middle resizes.
As i see applies css values from "default" and if inside #media screen and (max-width: 400px) { exists different values from "default", then applies different values (different values change "default" values).
Seems all works. But may be some better way how to do all?
Another way may be to write (repeat) whole rules for each width of window. And do not write "default" values. But in such case code would be longer....
One suggestion in the above code.
Since #right { display:none} applies for all widths less than 700, you can add it in #media (max-width:700px).
Use max-width media queries in descending order and keep changing the styles for the lower width screens.

How do i assign a fixed width property to the container class in bootstrap. I have tried to assign a width value to the major container but when i resize the browser, the content of the container become unresponsive.
<body>
<div class="container"> //This is the major container
</div>
</body>
You can either use <div class="container-fixed"> or your own media query in which you can specify the custom width for various resolution.
Here is an sample
#media (min-width: 768px) {
.my-custom-container{
width:600px;
}
}
#media (min-width: 992px) {
.my-custom-container{
width:720px;
}
}
#media (min-width: 1200px) {
.my-custom-container{
width:900px;
}
}
The default Bootstrap .container class has 15px padding on both left and right sides.
You can adjust this by adding additional padding to your container:
.container { //or use a custom class like .custom-container
padding-left: 100px;
padding-right: 100px;
}
Or you could also adjust the width of your container like so:
.container {
width: 75%;
}
Both of these solutions will maintain responsiveness, but the first one will potentially cause issues with smaller screens. You could also use %'s there as well (like padding-left:10%).
Whatever you end up using depends on your specific situation and the desired outcome. You should play around with different screen resolutions and pages on your site to make sure whatever you go with works well.
I have a website with all content centered. The content has a width of 500px.
I'm only concerned about the content (the 500px) to be visible, how much of the gutter doesn't matter.
For desktop displays I have the following CSS rules:
margin: 0 auto;
width: 500px;
What should be applied so that the content area gets displayed in it's entirety on as many screen sizes as possible (i.e. as small as 320px)?
to support different screen sizes you should use percentage, not pixel. But in case you are more comfortable using fixed width (using pixel) you can use media queries to achieve that.
.container { //start with the smallest screen width
width: 300px;
margin: 0 auto;
}
#media screen and (min-width: 40em) { // 640px
.container {
width: 500px;
}
}
But I do recommend you to use percentage instead of pixel. Hope you find this useful.
I was experimenting with media queries to see the effects.
So I tried using min-width(480px) query to change the width of a div from 100% to 520px when the window was maximised but the width of the div stays 100%.
The code:
#box {
margin: auto;
background: white;
width: 100%;
}
// Media Queries
#media only screen and (min-width: 480px) {
#box {
width: 200px;
max-width: 200px;
background: black;
}
}
So my question is, why does the width of the #box stay as 100% when the window is maximised?
What am I doing wrong?
jsFiddled here is your code with min-width:480px. It applies when the size of available space is bigger than 480px (the black box)
try max-width. This context will apply when available screen space is less then 480 pixels. jsFiddled here, black box will be applied when available space width is lesser than 480px
#media only screen and (max-width: 480px) {
#box {
width: 200px;
max-width: 200px;
background: black;
}
}
So, your #box is by default 100% width except when the available space is greater than 480px. your code is working OK.
Maybe it's the comment : // Media Queries witch caused an error ?
I think you have the media query wrong. As you have it now, it's changes the content over 480px. Where I think you want it under 480px.
So it should be:
#media only screen and (max-width: 480px) {
//code
}
Hence, (max-width: xxx) not, (min-width: xxx).
Example fiddle
I had commented the code using // syntax by accident which isn't supported in CSS, hence the code below that line of comment not working. It now works after I changed it /**/ syntax.
