I have a div with a set size which I need to add a background image to. However I would like the image to fill the width of the div but be cropped to take up up say one third to a half of the height of the div. I've managed this using a pseudo element like so:
<div class="card-wrap bg-img-3"><div class="card">
<div class="top">
<h2 class="white">Heading</h2>
</div>
</div></div>
.bg-img-3:before {
content: '';
position: absolute;
width: 9.4cm;
height: 3cm;
z-index: -1;
background: url("./img/video.png");
}
But using this technique I don't seem to able to add a background colour to the bottom half of the div.
How can I use a cropped background image and background colour on the same div?
You can use after to set background color if you want
.bg-img-3:after {
content: '';
position: absolute;
top: 0;
bottom: 0;
left: 0;
right: 0;
z-index: -2;
background-color: #f00;
}
If you call the background property alone, you will generalize your command. Instead, be more specific and use background-image. This will tell the browser you'll want to use various properties for your background. You may want to remove the pseudo element ":after" as I believe it is not required in this method. Try the following in your style:
.bg-img-3 {
content: '';
position: absolute;
width: 9.4cm;
height: 3cm;
background-image: url("./img/video.png");
background-repeat: no-repeat;
background-size: 9.4cm 1.5cm;
background-color: #999;
}
Please let me know if this helps. Cheers.

I'm trying to apply a watermark(with an image) to an image inside a carousel. I replaced my previous ngx-bootrap/carousel by ng-image-slider. In my previous code, I use this and it works fine:
.watermarked:after {
content: "";
display: block;
width: 100%;
height: 100%;
position: absolute;
top: 0px;
left: 0px;
background-image: url("/assets/images/confidential.png");
background-size: 300px 300px;
background-repeat: space;
opacity: 0.9;
}
Now, I find the container in the DOM and located the classs to override the css by my custom watermark css (is what the author recommends):
ng-image-slider .ng-image-fullscreen-view .custom-image-main img {
content: '';
display: block;
background-image: url('/assets/images/confidential.png');
background-size: 300px 300px;
background-repeat: space;
opacity: 0.9;
border: 3px solid orange;
}
It 'works', because while the image is loading, I can see the background with my image, but after the load, it disappears..
While loading:
After the image load, the background get covered and I cannot see anything:
Is this a normal behaviour? Is possible to maintain the background in the front line?
Thanks!
You forgot to use ::after in your example code. Add that to the container of the image since ::after doesn't work on img. I would suggest the following, but make sure that either .custom-image-main or another parent in your slider has position: relative; or the absolute positioning won't work.
.ng-image-slider .ng-image-fullscreen-view .custom-image-main::after {
content: '';
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
background-image: url('/assets/images/confidential.png');
...etc
}
I'm going nuts! lol
I'm trying to position one image to the bottom of a page but it only works if the page is on large width...say 1360px, but when I shrink the with exactly to the 1206px and less, the body the image is pushed up creating a padding to the bottom as you can see in the image bellow (The image is represented by the green box).
The green image is positioned using this CSS:
body::after {
content: "";
width: 556px;
height: 767px;
position: absolute;
bottom: 0;
right: 10%;
display: block;
background-image: url("imagens/ghost-dog.png");
background-size: contain;
background-repeat: no-repeat;
z-index: -1;
}
And also there is a transparency (this purplish shadow) I added using other property that don't sticky to the bottom too. Using this CSS:
body::before {
background-color: rgba(0, 0, 0, 0.1);
position: absolute;
display: block;
content: "";
top: 0;
left: 0;
width: 100%;
height: 100%;
z-index: -1;
}
And last to make my mind go round and round there is a background to the body but it fits ALL screen as expected:
body {
color: #fff;
font-size: 15px;
line-height: 21px;
font-family: "comfortaa-regular";
background-color: var(--cor-roxa);
background-image: url("imagens/logo-bg.svg");
background-repeat: repeat;
}
html, body {
height: 100%;
}
I've already tried to position body relative, but it didn't solve the issue. I don't know if it matter but I'm using bootstrap and my divs are organized like the image below:
Any suggestions?
Without any example to review this is difficult to determine a cause. That said, what immediately comes to mind is a child element with a margin is overflowing it's parent container pushing the window boundary but not it's parent containers boundary.
I would inspect your elements and toggle any margins to see if this has any effect.
If you add your code to a fiddle I can take a look and update this if I notice the issue.
<div class="shouldBeOverlapped">
content
</div>
now I want to add another div on it (e.g. waiting) so it will 100% cover it and make it unclickable, preferably transparented. How to do it?
Try to search for "overlay". This will be the right thing.
Example here:
#overlay {
height: 100%;
width: 100%;
background-color: black;
opacity: 0.5;
position: absolute;
top: 0;
left: 0;
}
<div class="shouldBeOverlapped">
content
</div>
<div id="overlay"></div>
You can try to put that waiting div as a :before. Although it is limited, it can be easy to set up.
#textToHide {
background: yellow;
position: relative;
width: 300px;
padding: 10px;
}
#textToHide:before {
content: '';
position:absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
}
<div id="textToHide">
This text is protected against selection... although we could still look for it in the source code...
</div>
You need a containing div element with it's position attribute set to relative. This defines the bounds of the overlay. Without it the overlay will look up the DOM until it finds a parent it can get it's positioning information from. If it doesn't find one, it will cover the entire page body.
I've created a JSFiddle for you here: https://jsfiddle.net/aogd164t/
Try removing position: relative from the container class and see the result.
I've got a div with a background color and a transparent background image.

I want to be change the opacity of the image, but leave the background color unaffected. But when I set the opacity, both change.
Is there a way to do this?
Use an rgba color value and remove the opacity. For a white overlay you may use background:rgba(255,255,255, 0.5); while the last value (in this case 0.5) defines your transparency.
You can check this fiddle.
You can add a ::before pseudo-element to handle the background color, so that the ::after element has the image and opacity change, and the background-color can be unaffected. Note that the background-color of the actual .watermark element needs to be transparent, as the z-index:-1 will push the pseudo-elements behind the actual one.
.watermark {
width: 300px;
height: 100px;
display: block;
position: relative;
}
.watermark::before, .watermark::after {
content: "";
top: 0;
left: 0;
bottom: 0;
right: 0;
position: absolute;
z-index: -1;
}
.watermark::before {
background:#C52F11;
}
.watermark::after {
background: url(https://www.google.com/images/srpr/logo11w.png) no-repeat;
opacity: 0.2;
}
<div class="watermark">
<div class="col-md-12">Something else</div>
<div class="col-md-12">Something more..</div>
<div class="col-md-12">Something at the end</div>
</div>

I would recommend to use two divs. Its always a good idea to have two divs in overlapping stuffs with relative and absolute. Moreover, it adds long life to your code structure before you have to change it otherwise.
It's a trick:
Insert the image into the webpage anywhere(regardless of the size).
Set the desired opacity by style="opacity:0.7;" (for opacity= 0.7).
Take a snapshot of that image.
Remove that image and insert the snapped image where ever you want.
I'm trying to set quite a complex border image to my website. I can't make it a background-image because it's actually a border for a slide and the slide content has to go UNDER the border when it actually slides, and with background image I assume the content will just go above it.
So, basically I need help how to make this a border image for a div maybe. OR if there is a better approach then making this a border, let me know please.
Thank you.
Doing a transparet png image is not html, you need to do it with a software such Photoshop or Gimp else you can do it with messing around with divs
<style>
.screen {
height: 422px;
width: 820px;
}
.back {
position: absolute;
height: 422px;
width: 820px;
background-image:url('test.png');
}
.content {
position: absolute;
height: 320px;
width: 672px;
margin-left: 73px;
margin-top: 56px;
border-radius: 50px;
overflow:hidden;
}
</style>
<div class="screen" >
<div class="content" >
put here what ever you want to put inside
</div>
<div class="back" ></div>
</div>
this work with me with your image
You could use the before/after psuedo elements to attach your unusual "border" as a background image.
div.slide {
background: yellow;
position: relative;
}
div.slide:before {
display: block;
content: " ";
position: absolute;
width: 100%;
height: 100%;
background: url(slide-bg.png) no-repeat;
background-size: 100% 100%;
z-index: 1;
}

The demo uses an opaque to transparent gradient so you can see the effect. Your image just needs to have transparent areas for the text to show through, and opaque areas where it shouldn't. Add paddings to the .slide as appropriate.
