I try to change the size of a checkbox in bootstrap. I try it like this:
css:
.big-checkbox {width: 100px; height: 100px;}
HTML bootstrap:
<label class="big-checkbox">
<input type="checkbox" name="optradio">Reeks
</label>
#section scripts{
<link href="#Url.Content("~/Content/Stickerprinter.css")" rel="stylesheet" type="text/css" />
}
But I dont see changing the size.
Using width and height you can't change the dimensions of an input checkbox. In this way change the area of click but checkbox remain the same.
You can use this:
input[type=checkbox] {
transform: scale(1.5);
}
Check the difference: https://jsfiddle.net/88v0gq20/
You can use for bootstrap this plugin: http://plugins.krajee.com/checkbox-x/demo
Or you could create custom checkbox like in this tutorial: https://kyusuf.com/post/completely-css-custom-checkbox-radio-buttons-and-select-boxes
Try like this :
.big-checkbox > input {width: 100px; height: 100px;}
I have a bootstrap column defined as follows:
<div class="col-md-4 limit">
<img id="myImage" src="" class="img-responsive"/>
</div>
<style>
.limit {
max-height:500px;
overflow:hidden;
}
</style>
The source of the image is obtained programatically so I do not know in advance the height or width of my image. What I want to do is that the image in this column whose height is limited appear completely inside of the div. With the img-responsive class I have achieved the image to horizontally fill my column, however, as this class also sets the height to auto, most of the time this causes the image to overflow and be hidden. I do not want my image to overflow in any way.
So, lets say that my column measures:
Width: 300px (defined by bootstrap)
Height: 500px (.limit)
And my image dimensions are:
Width: 600px
Height: 1500px
The current configuration makes the image shrink to 300px x 750px. As its container is set to only 500px, this causes the last 250px to be lost inside the overflow. I would like to image instead to be resized to 200px x 500px in order for it to completely into the containing div
How can I do this?
Thanks!
Try this:
<div class="row">
<div class="col-md-4">
<div class="limit">
<img src="images/yourimage.png" alt="" />
</div>
</div>
</div>
<style type="text/css">
.limit{
width: 300px;
height: 500px;
max-height: 500px;
overflow: hidden;
}
.limit img{
width: 100%;
height: 100%;
}
</style>
You could try to inherit the height or the width of the parent div (as both would not contain proportions). This could only work if you have the same type of img (all portret or landscape). Other solution is to calculate the dimensions based on the max width/height of the img in your program language. Pick the one that matches the condition (both var <= max value). Then echo the solution in your html.

Let's say I have a div where I have applied "container-fluid".
How can I change it to "container" when the viewport is below 1200px (large devices) ?
I know that I can duplicate the code and use something like this:
<div class="container-fluid hidden-md">...content here...</div>
<div class="container hidden-lg">...content here...</div>
But this doesn't feel good. Is there any other way to do this?
You could add a custom class and media query to your own stylesheet (loaded after bootstrap), so something like
.customcontainer {
border: 1px solid red;
}
#media(max-width:1200px) {
.customcontainer {
max-width: 300px; //or whatever you want max width to be
}
}
<link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container-fluid customcontainer">...content here...</div>
I just added the border and low px width for demonstration purposes
I am creating an email flyer and I have multiple images that I want at 140px by 140px but some are originally 300x300 or 400x400. I don't want to go resize each image as there can be quite a few and the flyer will be a weekly update so is it possible to use CSS to tell all images (or images that have classes) to resize to 140px?
I was going to post some code but it's quite a vague request so there no relevant code I can show to help my question.
maybe if I <span>...</span> and then give the span a class, would it be possible this way?
if your markup is for a newsletter you may force dimensions both with style attribute and with inline width and height attribute, e.g.
<img src="..." style="width:140px; height:140px" width="140" height="140" />
but, anyway, I strongly suggest to perform some kind of batch task for automatic resize of the images (e.g. using GruntJS), so you could save some precious bandwidth on the server in which you store your static assets. (conversely, if you embed images into the email, users will appreciate a lighter size)
Yeah add class to span and then:
span.yourclass img {
width: 140px;
}
I think I might be understanding this, but some simple css should work :
css :
img.small {
width: 140px;
height: 140px;
}
OR if you want to do all img's under a specific element :
.thumbs img {
width: 140px;
height: 140px;
}
html :
<img src="pic.jpg" class="small">
<div class="thumbs">
<img src="pic.jpg">
<img src="pic.jpg">
<img src="pic.jpg">
</div>
Or if they are dynamically generated, you can eliminate the css and just go :
<img src="pic.jpg" width="140" height="140">
You can set width and height for all images. Add "max" keyword to be sure.
img{
max-width:140px !important;
max-height:140px !important;
}
If you simply want ALL images on the page to resize, add the following into your CSS:
img{ width: 140px; }
This will proportionally set the height/width and I'm assuming all you images are square ?
If not, add 'height: 140px' but this will distort an image that isn't square.
wrap your images with div.class then write a single css to resize all the images which are wrapped by that div
MARK-UP::
<div class="imageWrapper">
<img src="/path/to" />
<img src="/path/to" />
<img src="/path/to" />
</div>
CSS::
.imageWrapper{
overflow:hidden;
}
.imageWrapper img{
width:400px;
height:400px;
}
I have a few images on my page. I'm finding that the page starts to render before the images have been loading (which is good), but that the visual effect is not great. Initially the user sees this:
--------hr--------
text
Then a few milliseconds later the page jumps to show this:
--------hr--------
[ ]
[ image ]
[ ]
text
Is there a simple way that I can show a grey background image of exactly the width and height that the image will occupy, until the image itself loads?
The complicating factor is that I don't know the height and width of the images in advance: they are responsive, and just set to width: 100% of the containing div. This is the HTML/CSS:
<div class="thumbnail">
<img src="myimage.jpeg" />
<div class="caption">caption</div>
</div>
img { width: 100% }
Here's a JSFiddle to illustrate the basic problem: http://jsfiddle.net/X8rTB/3/
I've looked into things like LazyLoad, but I can't help feeling there must be a simpler, non-JS answer. Or is the fact that I don't know the height of the image in advance an insurmountable problem? I do know the aspect ratio of the images.
Instead of referencing the image directly, stick it within a DIV, like the following:
<div class="placeholder">
<div class="myimage" style="background-image: url({somedynamicimageurl})"><img /></div>
</div>
Then in your CSS:
.placeholder {
width: 300;
height: 300;
background-repeat: no-repeat;
background-size: contain;
background-image: url('my_placeholder.png');
}
Keep in mind - the previous answers that recommend using a div background approach will change the semantic of your image by turning it from an img into a div background. This will result in things like no indexing of these images by a search crawler, delay in loading of these images by the browser (unless you explicitly preload them), etc.
A solution to this issue (while not using the div background approach) is to have a wrapper div to your image and add padding-top to it based on the aspect ratio of the image that you need to know in advance. The below code will work for an image with an aspect ratio of 2:1 (height is 50% of width).
<div style="width:100%;height:0; padding-top:50%;position:relative;">
<img src="<imgUrl>" style="position:absolute; top:0; left:0; width:100%;">
</div>
Of course - the major disadvantage of this approach is that you need to know the aspect ratio of the image in advance.
There is a really simple thing to check before you start looking into lazy-loading and other JavaScript. Make sure the JPEG images you are loading are saved with the 'progressive' option enabled!
This will cause them to load the image iteratively, starting with a placeholder that is low-resolution and faster to download, rather than waiting for the highest resolution data before rendering.
It's very simple...
This scenario allows to load a profile photo that defaults to a placeholder image.
You could load multi CSS background-image into an element. When an avatar photo fails, the placeholder image appears default of div.
If you're using a div element that loads via a CSS background-image, you could use this style:
#avatarImage {
background-image: url("place-holder-image.png"), url("avatar-image.png");
}
<div id="avatarImage"></div>
Feel free to copy this:
<script>
window.addEventListener("load", function () {
document.getElementById('image').style.backgroundColor = 'transparent';
});
</script>
<body>
<image src="example.example.example" alt="example" id="image" style="background-color:blue;">
</body>
I got this from here: Preloader keeps on loading and doesnt disappear when the content is loaded.
Apart from all solutions already mentioned, the last solution would be to hide the document until everything is loaded.
window.addEventListener('load', (e) => {
document.body.classList.add('loaded');
});
body {
opacity: 0;
}
body.loaded {
opacity: 1;
}
<div id="sidebar">
<img src="http://farm9.staticflickr.com/8075/8449869813_1e62a60f01_b.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-1.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-2.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-3.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-4.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-5.jpg" />
<img src="https://www.nla.gov.au/sites/default/files/pic-6.jpg" />
</div>
Or show some animation while everything is loading:
window.addEventListener('load', (e) => {
document.body.classList.add('loaded');
});
.loader {
border: 16px solid #f3f3f3;
border-radius: 50%;
border-top: 16px solid #3498db;
width: 70px;
height: 70px;
-webkit-animation: spin 2s linear infinite;
/* Safari */
animation: spin 2s linear infinite;
position: absolute;
left: calc(50% - 35px);
top: calc(50% - 35px);
}
#keyframes spin {
0% {
transform: rotate(0deg);
}
100% {
transform: rotate(360deg);
}
}
body :not(.loader) {
opacity: 0;
}
body .loader {
display: block;
}
body.loaded :not(.loader) {
opacity: 1;
}
body.loaded .loader {
display: none;
}
<div class="loader"></div>
<div id="sidebar">
<img src="http://farm9.staticflickr.com/8075/8449869813_1e62a60f01_b.jpg" />

The only thing I can think of, to minimize the jump effect on your text, is to set min-height to where the image will appear, I would say - set it to the "shorter" image you know of. This way the jump will be less evident and you won't need to use lazyLoad or so... However it doesn't completely fix your problem.
Here's one naive way of doing it,
img {
box-shadow: 0 0 10px 0 rgba(#000, 0.1);
}
You can manipulate the values, but it creates a very light border around the image that doesn't push the contents. Images can load at whatever time they want, and you get a good user experience.
Here is what I did with Tailwind CSS, but it's just CSS:
img {
#apply bg-no-repeat bg-center;
body.locale-en & {
background-image: url("data:image/svg+xml;utf8,<svg width='100' height='100' viewBox='0 0 100 100' xmlns='http://www.w3.org/2000/svg'><text x='50%' y='50%' style='font-family: sans-serif; font-size: 12px;' dominant-baseline='middle' text-anchor='middle'>Loading…</text></svg>");
}
body.locale-fr & {
background-image: url("data:image/svg+xml;utf8,<svg width='100' height='100' viewBox='0 0 100 100' xmlns='http://www.w3.org/2000/svg'><text x='50%' y='50%' style='font-family: sans-serif; font-size: 12px;' dominant-baseline='middle' text-anchor='middle'>Chargement…</text></svg>");
}
}
You can find the width and height of the images in the developer tools console, for example in Chrome you can click the cursor icon in the developer tools console and when you hover on the page it will highlight all the properties of the elements in the page.
This will help you find the width and height of the images, because if you hover on top of your images it will give you the dimensions of the image and other more properties. You can also make an individual div for each image and make the div relative to the images width and height. You can do it like this:
The main div will contain the images and also the background-div which is below the image.
HTML:
<html>
<head>
<meta charset="utf-8">
</head>
<body>
<div class=".mainDiv">
<div class="below"></div>
<img src="https://imgix.bustle.com/uploads/image/2020/2/13/da1a1ca4-95ec-40ea-83c1-4f07fac8b9b7-eqb9xdwx0auhotc.jpg" width="500"/>
</div>
</body>
</html>
CSS:
.mainDiv {
position: relative;
}
.below {
position: absolute;
background: #96a0aa;
width: 500px;
height: 281px;
}
img {
position: absolute;
}
The result will be that .below will be below the image and so when the image has trouble loading the user will instead see the grey .below div. You cannot see the .below div because it is hidden below the image. The only time you will see this is when the loading of the image is delayed. And this will solve all your problems.
I have got a way. But you will need to use JavaScript for it.
The HTML:
img = document.getElementById("img")
text = document.getElementById("text")
document.addEventListener("DOMContentLoaded", () => {
img.src = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAOEAAADhCAMAAAAJbSJIAAAAA1BMVEWIiIhYZW6zAAAASElEQVR4nO3BgQAAAADDoPlTX+AIVQEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAADwDcaiAAFXD1ujAAAAAElFTkSuQmCC";
text.innerHTML = "Loaded but image is not";
});
window.onload = function() {
img.src = "https://media.geeksforgeeks.org/wp-content/uploads/20190913002133/body-onload-console.png";
text.innerHTML = "Image is now loaded";
};
#img {
width: 400px;
height: 300px;
}
<hr>
<img id="img" src="https://media.geeksforgeeks.org/wp-content/uploads/20190913002133/body-onload-console.png">
<p>Here is the Image</p>
<p id="text">Not Loaded</p>
