How to render a background-image in a PDF document using CSS - css

I have a pdf document generated by my web app. I want to style it using CSS by adding a background image. The dimensions of the image are 250 by 130 px. The problem is that the background image appears blurry when the page is rendered on the browser. Please assist?
CSS
body{
background-image: url('img/logo.jpg');
background-position: center;
background-repeat: no-repeat;
height: 250px;
width: 130px;
padding: 0;
margin: 0;
}

Create a background pattern with css

I have a design made with figma:
I have the shapes svg, I want to create the same design to be a background for my website.
Is it possible to do with css?

SVGs are a valid file type for the CSS url function.
html, body {
height: 100%;
}
body {
margin: 0;
background: url(https://upload.wikimedia.org/wikipedia/commons/e/ef/Stack_Overflow_icon.svg);
background-size: contain;
background-repeat: no-repeat;
}

Fully display background image

I'm setting up a site, and want to create a responsive background image but I'm getting only single line with background image. What property should i need to use to make the entire background image to fit?
I created 2 files,
index.html :
<div id="logo">Test</div>
style.css :
#logo {
background-image: url("bg.png");
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
}
I tried many times but only single line gets background image. I want the background image to be fully displayed on screen without using height property which i think makes site less responsive.

you should change the height of logo div and set it as full height by adding height:100% for the body and logo div, your code should look like below code
html, body
{
height: 100%;
}
#logo {
background-image: url("bg.png");
background-position: center center;
background-repeat: no-repeat;
background-attachment: fixed;
background-size: cover;
height:100%;
}

If you want the image to have the same height as the screen you can use height:100vh. But if you want only the image full size you can do this like this :
html, body {
height: 100%;
margin: 0;
padding: 0;
}
#image{
max-height: 100%;
max-width: 100%;
}
#text{
position: absolute;
color: white;
top: 0
}

How do I make the sprite images generated by webpack-spritesmith responsive using CSS?

When using webpack-spritesmith to generate a sprite image, the css generated typically looks like this:
.icon-AutoFollow {
background-image: url(images/sprite.jpg);
background-position: -2222px 0px;
width: 800px;
height: 999px;
}
.icon-Battery {
background-image: url(images/sprite.jpg);
background-position: -3284px -1372px;
width: 278px;
height: 278px;
}
which is nice if I want to width of the images to be 800px for AutoFollow and 278px for battery. However, how would I go about making those images full-width responsive (the equivalent of a <img> tag with width: 100%; and height: auto;)?

CSS/XHTML - what does the overlay.png do in this template?

http://html5up.net/big-picture
The overlay.png does make my background brighter. But I do not want to deleted it unless I understand what this png does. Do you guys have a clue?
The overlay.png is used here:
#intro {
background: url('images/overlay.png'), url('../images/intro.jpg');
background-size: 256px 256px cover;
background-attachment: fixed, fixed;
background-position: top left, top center;
background-repeat: repeat, no-repeat;
color: #c2b090;
}
.image:before
{
content: '';
position: absolute;
left: 0;
top: 0;
width: 100%;
height: 100%;
background: url('images/overlay.png');
}

It's making your background image lighter. overlay.png is a partially transparent blue-ish graphic that overlays intro.jpg. It's set as the first background image of your main section tags. If you delete it, your big images will not be washed out, but it will result in a failed HTTP request because your CSS is still referencing it. If you want to delete the image, you should remove reference to it in your style.css file if you can.

CSS problem with background-attachment:fixed;

I have a Joomla site that i have created a custom theme. The site is http://esn.teipir.gr/.
I have two images right and left that i want them to have background image fixed.
I use the following CSS rules
div.backgroundboxleft {
background-attachment: fixed;
background-image: url("/images/back_1.png");
float: left;
height: 822px;
top: 40px;
width: 457px;
}
and
div.backgroundboxright {
background-attachment: fixed;
background-image: url("/images/back_2.png");
float: right;
height: 822px;
top: 40px;
width: 457px;
}
If i remove the background-attachment all is OK with the images but when i add with firebug the following code everything messes up.Can you help me making the pages stay fixed without the background color being on top of the image?
Thanks

When you set background-attachment:fixed it fixes the background in relation to the window. So you would then need to adjust the background-position of your images so they appear in the right place. If you replace your backgroundproperties with the css below it will line up properly.
div.backgroundboxleft {
background-image: url("/images/back_1.png");
background-attachment: fixed;
background-position: 0 44px;
background-repeat: no-repeat;
}
div.backgroundboxright {
background-image: url("/images/back_2.png");
background-attachment: fixed;
background-position: 1323px 44px;
background-repeat: no-repeat;
}
Live example: http://jsfiddle.net/tw16/6fZ96/embedded/result/
To clarify background-attachment:fixed stops the background from scrolling with the window. So if your viewport is too small and you have to scroll horizontally or vertically the background will not move (i.e. it will be overlapped). More information can be found here.
