I have an image of 320px x 320px and max-width:620px for the container div
My problem is that I want it to appear at firs,with the original size, then if resize the window, then decrease the proportions of the image.
div.container {
max-width: 620px;
background: yellow
}
img {
text-align: center;
display: block;
margin: 0 auto;
width: 100%;
height: auto;
}
<div class="containe">
some text
<img class="img" src="http://via.placeholder.com/320x320/33ff99/555555?text" /></div>
I can not use max-width:320px in the image, because, the image generates dinamically and It usually have some other size values
How can I do it?
You could use #media queries, you can read more about them here.
If you resize your window let's say smaller than 768px. You could change your image size. The css below will make the image take the full width of the container while keeping its aspect ratio.
#media screen and (max-width: 768px) {
#img {
max-width:100%;
height:auto;
}
}
I have .psd design for client site, graphic designer drew container width up to 1920px, and I need a help how to properly set up width of container to 1920px.
I know how to set up smaller
#media (min-width: 1200px)
.container {
width: 1170px;
}
Instead of forcing your containers to 1920px and overriding the default bootstrap grid sizes, you may want to look at .container-fluid, which is inside Bootstrap's packaged css.
Containers
Bootstrap requires a containing element to wrap site contents and house our grid system. You may choose one of two containers to use in your projects. Note that, due to padding and more, neither container is nestable.
Use .container for a responsive fixed width container.
<div class="container">
...
</div>
Use .container-fluid for a full width container, spanning the entire width of your viewport.
<div class="container-fluid">
...
</div>
Link: http://getbootstrap.com/css/#overview-container
You could utilize Bootstrap's container-fluid class to fill the entire width first, then you can restrict the width responsively... Here is an example in Sass:
.wide-container {
#extend .container-fluid; // which has max-width: auto; (full)
}
// on medium screens and beyond...
#include media-breakpoint-up(md) {
.wide-container {
max-width: 1470px; // limit the width here!
}
}
Just reuse the media query you have above, and simply decide when you want the container to change to that size (something greater than 1920px).
#media (min-width: YOUR VALUE HERE)
.container {
width: 1920px;
}
OR, upon reading your question again, you said, "up to 1920px", so a fluid container?
Then simply set:
.container {
max-width: 1920px;
width: 100%;
}
Your problem is not clear enough. but if you want to set up 1920px wide container, just override the default container width with "!important". like this,
.container { width: 1920px !important; }
Or if you wish to 1920px container only for larger displays, you can use media query like this,
#media (min-width: 2400px) {
.container {
width: 1920px;
}
}
this rule will apply only for displays that is at least 2400px wide.
You can apply your own CSS according to the screen size you want to show as the below example will work on a larger resolution size than 1599px.
#media (min-width: 1600px)
.container {
max-width: 1500px;
}
You could override BootStrap's default styling as the answers above describe, or you could create a new class such as:
.container.wide {
width: 1920px;
}
Then add the class to the container <div>'s such as:
<div class="container wide">
CONTENT
</div>
This ensures only the <div>'s you add the wide class to are effected, meaning you're still free to use <div class="container"> for normal BootStrap container behavior if required.
EDIT
As Vikas has said in his comment, the above style would apply also on mobile. In this case, just wrap in a media query as follows:
#media (min-width: 1950px) {
.container.wide { width: 1920px; }
}
This css will override bootstrap's container sizing. Adjust the max-width values as needed. Tested with bootstrap 4.6.1
/* Override bootstrap to make containers wider by 60px */
#media screen and (min-width: 576px) {
.container, .container-sm {
max-width: 600px;
}
}
#media screen and (min-width: 768px) {
.container, .container-md, .container-sm {
max-width: 780px;
}
}
#media screen and (min-width: 992px) {
.container, .container-lg, .container-md, .container-sm {
max-width: 1020px;
}
}
#media screen and (min-width: 1200px) {
.container, .container-lg, .container-md, .container-sm, .container-xl {
max-width: 1200px;
}
}
Based on your reactions you probably want
.container{
width: 1920px !important;
}
though I don't understand why :). On every smaller resolution it will scroll now.
I'm currently working on a project where we use a slider with images. This slider is displayed with width 100%, and currently we're adjusting the height to make the slider responsive, in case the user resizes the browser window or visits the website using their phone.
However, the website is for an artist who obviously does not want the image to be altered in any way, especially not altering with the aspect ratio. So what we're looking into is having height: auto to adjust the image height correctly according to the width: 100%, without altering the image (aspect ratio) itself.
This does not work like intended however, using the following code:
#media (min-width:1600px) {
#header{
height:auto;
width: 100%;
min-height: 630px;
background-size: 100% auto;
}
#slidershadow {
height: 630px;
}
}
We need to have some min-height, otherwise we cannot display the slider controls correctly. Here is a picture of our current situation (first image) and the expected behaviour (second picture).
Is there a way to resize our slider responsive, but keeping the following in mind:
The aspect ratio of the image cannot be altered;
We cannot crop images too much (only slightly);
There is a minimum height to keep in mind;
If it helps, all images in the slider have the same size.
You have to give a max-width:100% to your img.
Plus background-size only works when you are working with background-images.
Since you are applying max-width to your img there is no need to apply max-width to its parent #header
Last, but not least try not use min-height and height:auto at same time in the same selector.
Below is a working snippet according to the above comments:
img {
max-width: 100%;
height: auto
}
#media (min-width: 1280px) {
#header {
min-height: 500px;
}
}
#media (min-width: 1600px) {
#header {
min-height: 630px;
}
}
<div id="header">
<img src="http://placehold.it/1920x630" />
</div>
How do I setup the with to say 1200px when my website runs on a regular PC or Mac?
Apparently Bootstrap has 12 columns in it's grid of 60px each plus gutters.
Is there a way to enlarge the column's basic width?
You can override the class .container in your css
.container {
width: 1200px;
}
You can try this :
Body {width:100%;}
#media (min-width: 950px) {
.container {
width: 1200px;
}
}
All this means is if your page width is small than 950px it will change the container to 1200px;
Do you want it responsive?

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.
