Making div element background transparent to background image CSS - html

I would like to make a parallax effect within my website, however I am unable to set the background of a DIV element to be transparent, despite using background-color: transparent.
Essentially, I would like to solely display the text within a DIV, and remove the background color.
By using W3Schools..
body, html {
height: 100%;
}
.parallax {
/* The image used */
background-image: url('http://www.zastavki.com/pictures/originals/2013/Photoshop_Image_of_the_horse_053857_.jpg');
/* Full height */
height: 100%;
/* Create the parallax scrolling effect */
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
.parallax2 {
/* The image used */
background-image: url('http://www.qygjxz.com/data/out/114/4676052-image.png');
/* Full height */
height: 100%;
/* Create the parallax scrolling effect */
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
/* Turn off parallax scrolling for tablets and phones. Increase the pixels if needed */
#media only screen and (max-device-width: 1024px) {
.parallax {
background-attachment: scroll;
}
}>
<div class="parallax"></div>
<div style="height:100px;background-color:transparent;font-size:36px">
Some text goes here, need to try to make the background of this transparent? Any ideas?
</div>
<div class="parallax2"></div>
Thank you

If you want to set the background color to transparent you can do all of these.
background-color: ;
background-color: transparent;
background-color: rgba(0, 0, 0, 0);
but in this case, you need to set a different position here is the code I hope this is what you were looking for
<div style="height:100px;font-size:36px; border:1px solid red; position: absolute;">
Some text goes here, need to try to make the background of this transparent? Any ideas?
</div>

If you don't assign a background-color to your div, it would be transparent automatically. That's the default. I made a jsfiddle and tested it to make sure.
<div style="height:100px;font-size:36px; border:1px solid red;">
Some text goes here, need to try to make the background of this transparent? Any ideas?
</div>
If for any reason it didn't work, I would make a 2*2 transparent PNG in Photoshop and assign in as background-color, repeated in x and y directions both.
It's not a standard solution but will work surely. :D

I had a similar problem a few days ago.
You can easily write:
background: none;
or
background: transparent;
and then the element become transparent and the element under it will be visible.
But the text is still there.

CSS Background Image not appearing on website

I'm building a website from CSS and HTML. I'm up to the point of adding a background image to my website. The trouble is, the image isn't showing up as the website's background.
My CSS code:
.bg {
background: url('https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg?i10c=img.resize(height:160)');
height: 50%;
/* Center and scale the image nicely */
background-position: center;
background-repeat: repeat-x;
background-size: cover;
}
<div class="bg"></div>
Just ask me if you need any more code from my website.
Edit: This is not a clone, I've tried every other solution that I've come across on here, and nothing works.
This works fine if you use fixed height:
In the below case I have used 100px;
.bg {
background: url('https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg?i10c=img.resize(height:160)');
height: 100px;
/* Center and scale the image nicely */
background-position: center;
background-repeat: repeat-x;
background-size: cover;
}
<div class="bg">
</div>
But if you want it to be 100% of the screen you can always go with 100vh
.bg {
background: url('https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg?i10c=img.resize(height:160)');
height: 100vh;
/* Center and scale the image nicely */
background-position: center;
background-repeat: repeat-x;
background-size: cover;
}
<div class="bg">
</div>

Hope this was helpful for you.
The background image for a page can be set like this:
body {
background-image: url("paper.gif");
}
so maybe you can change your code become :
.bg {
background-image: url('https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg?i10c=img.resize(height:160)');
height: 100px;
/* Center and scale the image nicely */
background-position: center;
background-repeat: repeat-x;
background-size: cover;
}
If you want to add background image to whole HTML Page then use body tag.
body {
background-image: url("https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg");
}
and if you want to add background to specific class then use this
.bg {
background-image: url('https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg');
}
in that adjust your height accordingly. if you want to add to full class then use
height:100% else adjust it with your own condition.
The image that the OP refers to is a resized version of the original. This solution uses the original image along with CSS that uses a height of 100vh (as recommended by #weBBer) and auto for the width. The background position remains with a center value. It seems needless to repeat the image so the CSS uses no-repeat. This works with Google Chrome (version 49).
.bg {
background-image: url(https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg);
width:auto;
height:100vh;
background-position: center;
background-repeat: no-repeat;
background-size:cover;
}
<div class="bg"></div>
The result is a centered image that fills the page due to background-size property being set to cover as well as the height property set to 100vh, i.e. 100% of the view port height; see more about this and other measurements here.
If you only wanted to fill the portion within the dimensions of the DIV then you could alter the CSS and replace background-size property with object-fit, as follows:
.bg {
background-image: url(https://ak9.picdn.net/shutterstock/videos/12047219/thumb/10.jpg);
height:480px;
margin-left:auto;width:100%;margin-right:auto;
background-position: center;
background-repeat: no-repeat;
object-fit:cover;
}
<div class="bg"></div>

How to create a parallax website in html (why will my bg image not cover the whole screen?)

I am creating a parallax bg but the bg image does not cover the full screen could anyone tell me how to fix it? This is what I have as far as the parallax..

Making background image reveal bottom first when scrolling?

I am attempting to make a feature like https://www.artyofficial.com/ has.
When scrolling down, the bottom of the second image will appear while the first image starts to get cut away. How is something like this achievable with CSS? I would post a style sheet but unfortunately I don't even know where to begin here.
What you are looking for is the parallax scrolling effect
The most important property is the background-attachment: fixed; here.
I made you a JSFiddle easy as possible, take a look at it.
I would start by looking at the background-attachment property, it has a value of:
fixed The background is fixed with regard to the viewport
It is called as parallax effect. You can refer to link: Parallax Effect
<style>
.parallax {
/* The image used */
background-image: url("img_parallax.jpg");
/* Set a specific height */
height: 500px;
/* Create the parallax scrolling effect */
background-attachment: fixed;
background-position: center;
background-repeat: no-repeat;
background-size: cover;
}
</style>
<!-- Container element -->
<div class="parallax"></div>
You just need to give all your such consecutive div's background-attachment: fixed. Check the example below:
.panels{
width: 100vw;
height: 100vh;
background-attachment: fixed;
background-size: cover;
background-position: center center;
}
.panels:nth-child(1){background-image: url('http://lorempixel.com/400/200/sports/');}
.panels:nth-child(2){background-image: url('http://lorempixel.com/400/200/nightlife/');}
.panels:nth-child(3){background-image: url('http://lorempixel.com/400/200/cats/');}
.panels:nth-child(4){background-image: url('http://lorempixel.com/400/200/food/');}
.panels:nth-child(5){background-image: url('http://lorempixel.com/400/200/nature/');}
/* this is for hiding stackoverflow console */
.as-console-wrapper{ display: none !important; }
<div class="panels"></div>
<div class="panels"></div>
<div class="panels"></div>
<div class="panels"></div>
<div class="panels"></div>

With CSS, how do I make an image span the full width of the page as a background image?

Say, like in this example here: http://www.electrictoolbox.com/examples/wide-background-image.html
When I do it, I end up getting white borders around the image no matter what I do. What am I doing wrong?
If you're hoping to use background-image: url(...);, I don't think you can. However, if you want to play with layering, you can do something like this:
<img class="bg" src="..." />
And then some CSS:
.bg
{
width: 100%;
z-index: 0;
}
You can now layer content above the stretched image by playing with z-indexes and such. One quick note, the image can't be contained in any other elements for the width: 100%; to apply to the whole page.
Here's a quick demo if you can't rely on background-size: http://jsfiddle.net/bB3Uc/
Background images, ideally, are always done with CSS. All other images are done with html. This will span the whole background of your site.
body {
background: url('../images/cat.ong');
background-size: cover;
background-position: center;
background-attachment: fixed;
}
You set the CSS to :
#elementID {
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) center no-repeat;
height: 200px;
}
It centers the image, but does not scale it.
FIDDLE
In newer browsers you can use the background-size property and do:
#elementID {
height: 200px;
width: 100%;
background: black url(http://www.electrictoolbox.com/images/rangitoto-3072x200.jpg) no-repeat;
background-size: 100% 100%;
}
FIDDLE
Other than that, a regular image is one way to do it, but then it's not really a background image.
​
the problem is the margin of body his default value is margin: 8px
and i make it margin : 0 so the image stretching and there is no white places

CSS background image to fit width, height should auto-scale in proportion

I have
body {
background: url(images/background.svg);
}
The desired effect is that this background image will have width equal to that of the page, height changing to maintain the proportion. e.g. if the original image happens to be 100*200 (any units) and the body is 600px wide, the background image should end up being 1200px high. The height should change automatically if the window is resized. Is this possible?
At the moment, Firefox looks like it's making the height fit and then adjusting the width. Is this perhaps because the height is the longest dimension and it's trying to avoid cropping? I want to crop vertically, then scroll: no horizontal repeat.
Also, Chrome is placing the image in the centre, no repeat, even when background-repeat:repeat is given explicitly, which is the default anyway.
There is a CSS3 property for this, namely background-size (compatibility check). While one can set length values, it's usually used with the special values contain and cover. In your specific case, you should use cover:
body {
background-image: url(images/background.svg);
background-size: cover; /* <------ */
background-repeat: no-repeat;
background-position: center center; /* optional, center the image */
}
Eggsplanation for contain and cover
Sorry for the bad pun, but I'm going to use the picture of the day by Biswarup Ganguly for demonstration. Lets say that this is your screen, and the gray area is outside of your visible screen. For demonstration, I'm going to assume a 16x9 ratio.
We want to use the aforementioned picture of the day as a background. However, we cropped the image to 4x3 for some reason. We could set the background-size property to some fixed length, but we will focus on contain and cover. Note that I also assume that we didn't mangle the width and/or height of body.
contain
contain
Scale the image, while preserving its intrinsic aspect ratio (if any), to the largest size such that both its width and its height can fit inside the background positioning area.
This makes sure that the background image is always completely contained in the background positioning area, however, there could be some empty space filled with your background-color in this case:
cover
cover
Scale the image, while preserving its intrinsic aspect ratio (if any), to the smallest size such that both its width and its height can completely cover the background positioning area.
This makes sure that the background image is covering everything. There will be no visible background-color, however depending on the screen's ratio a great part of your image could be cut off:
Demonstration with actual code
div > div {
background-image: url(http://i.stack.imgur.com/r5CAq.jpg);
background-repeat: no-repeat;
background-position: center center;
background-color: #ccc;
border: 1px solid;
width: 20em;
height: 10em;
}
div.contain {
background-size: contain;
}
div.cover {
background-size: cover;
}

Based on tips from https://developer.mozilla.org/en-US/docs/CSS/background-size I end up with the following recipe that worked for me
body {
overflow-y: hidden ! important;
overflow-x: hidden ! important;
background-color: #f8f8f8;
background-image: url('index.png');
/*background-size: cover;*/
background-size: contain;
background-repeat: no-repeat;
background-position: right;
}
Background image is not Set Perfect then his css is problem create so his css file change to below code
html {
background-image: url("example.png");
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
}
%; background-size: 100% 100%;"
I'm not sure what you're looking for exactly, but you really should check out these excellent blog posts written by Chris Coyier from CSS-Tricks:
http://css-tricks.com/how-to-resizeable-background-image/
http://css-tricks.com/perfect-full-page-background-image/
Read the descriptions for each of the articles and see if they're what you're looking for.
The first answers the following question:
Is there a way to make a background image resizeable? As in, fill the background of a web page edge-to-edge with an image, no matter the size of the browser window. Also, have it resize larger or smaller as the browser window changes. Also, make sure it retains its ratio (doesn't stretch weird). Also, doesn't cause scrollbars, just cuts off vertically if it needs to. Also, comes in on the page as an inline tag.
The second post's goal is to get the following, a "background image on a website that covers the entire browser window at all times. "
Hope this helps.
Just add this one line:
.your-class {
height: 100vh;
}
vh is viewport height.
This will automatically scale to fit the device' browser window.
Check more here: Make div 100% height of browser window
body{
background-image: url(../url/imageName.jpg);
background-attachment: fixed;
background-size: auto 100%;
background-position: center;
}
Try this,
element.style {
background: rgba(0, 0, 0, 0) url("img/shopping_bgImg.jpg") no-repeat scroll center center / cover;
}
I had the same issue, unable to resize the image when adjusting browser dimensions.
Bad Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
}
Good Code:
html {
background-color: white;
background-image: url("example.png");
background-repeat: no-repeat;
background-attachment: scroll;
background-position: 0% 0%;
background-size: contain;
}
The key here is the addition of this element -> background-size: contain;
Here's what worked for me:
background-size: auto 100%;
width: 100%;
height: 100vh;
background: url("../img/hero-bg.jpg") top center;
background-size: cover;
background-repeat: no-repeat;
background-position: 0% 0%;
background-size: 100% 100%;
if you set min-height, for example:
min-height: 100vh;
You can use the below code to fit your background easily
body {
background: url(images/background.svg);
min-height: 100vh;
background-repeat: no-repeat;
background-size: cover;
}
Setting background size does not help, the following solution worked for me:
.class {
background-image: url(blablabla.jpg);
/* Add this */
height: auto;
}
It basically crops the image and makes it fit in, background-size: contain/cover still didn't make it fit.
