I am trying to get an image to display an image using css background image, but I am not able to get the image to render.
CSS IS HERE:
body{
margin: 0px;
padding: 0px;
background-image: url(/steampunk/wallpaperSteampunk_B.jpg);
background-size: cover;
}
HTML IS HERE:
<html>
<head>
<link href="Main.css" rel="stylesheet"/>
<script src="jquery-1.10.2.min.js"></script>
<script src="JQUERY%20Main.js"></script>
</head>
<body>
<div id="box">
<div id="main"></div>
Everything from the CSS works except the BG image, What am I missing here?
Thanks in advance.
In case you are just using an html file opened within a browser, you need to make the url relative to the file and skip the / at the beginning of the url. Like so:
background-image: url(steampunk/wallpaperSteampunk_B.jpg);
In case you run your code within a web server, your url is correct and will just work because it is relative to the root of the host:
background-image: url(/steampunk/wallpaperSteampunk_B.jpg);
Except for the ' on background image path, you also need to set a height.

For example:
I have a page and the code is:
<!DOCTYPE html>
<html>
<head>
<style>
.wrap a {
color: red;
}
</style>
</head>
<body>
<div class="wrap">link</div>
</body>
</html>
And I have a common JavaScript component which will load a CSS file include the code below:
.wrap .link { color: blue; }
Then the link will change from red to blue.
Use iframe can fix this but cause another problem same like display two scrollbar or the lightbox overlay just in part of the page.
I can not change the CSS but I can write a JS loader so do you have some idea to fix this?
If a selector matches then a rule will apply until overridden by a rule (which sets the same property) further down the cascade.
You can either change your selectors to stop them matching the elements you don't want them to match, or you can override all your rules in that section.
Therefore, you'll have to adapt your markup and styles. You can precede every selector with #wrapper. For example, if a rule says a{color:red}, substitute that with #wrapper a {color:red;}.
HTML5 allows scoped stylesheets, but only Firefox supports it so far. However there is a you may try a jQuery solution: https://github.com/thingsinjars/jQuery-Scoped-CSS-plugin.
Hope it helps.
This might help you.
function changeColor(){
jQuery(".link").css('color','blue');

fairly new to js. I have a simple project in which all I have is an image twice the height of the screen. I want the webpage to open at the bottom of the page, so I have added the "window.scroll" funtion method in javascript. This works fine... most of the time. Sometimes, particularly if I test on a mobile device with a home server, the javascript just doesn't fire up and the page starts at the top. So my main question is: is there a way to do the same as "window.scroll" but with CSS, bypassing js altogether? And a second question I would have is, why is javascript so flaky? I am really new to web development and I have already twice (the other time with the "slide" method) had to use css instead of js because js doesn't work properly, or it needs to be cached etc... is this normal behaivour or just me really bad at writing it at this point? Thanks for your time. P
Here's the simple code:
$(document).ready(function(){
window.scroll(0,2000);
});
body {
margin: 0px;
padding: 0px;
}
img {
width: 100%;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!DOCTYPE html>
<html>
<head>
<title>Test</title>
<link rel="stylesheet" type="text/css" href="styles.css">
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" src="script.js"></script>
</head>
<body>
<img src="https://pixabay.com/static/uploads/photo/2016/10/18/21/22/california-1751455_960_720.jpg" width="100%" style="display: block;">
</body>
</html>
CSS:
body {
margin: 0px;
padding: 0px;
}
img {
width: 100%;
}
JavaScript:
$(document).ready(function(){
window.scroll(0,2000);
});
I think the problem is that the image takes time to load.So I think your event is fired however the image loads later and changes the page size again. The load event will fire after images are loaded.
try this code instead:
$(window).on("load", ,function(){
window.scroll(0,2000);
});
I am using the ASP Net Sprites package to create CSS Sprites on my website.
It is working, but the images it generates do not appear when printed.
The code generated at HTML level is:
<img class="getmecooking-logo-png" src="data:image/gif;base64,R0lGODlhAQABAIABAP///wAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" />
How can I get the logo image to appear when a user prints the page?
I have tried adding this in my print.css stylesheet, but it didn't work:
#siteLogo
{
visibility: visible;
}
The print.css is working fine and it is formatting the page as I want it to for other elements on the page. My only issue is that I can't get the site logo image to display when it is printed.
For Chrome and Safari you can add the following in your CSS:
#media print
{
* {-webkit-print-color-adjust:exact;}
}
For other web browsers unfortunately it's up to the user to manually select the option to print background images (e.g. for users with IE 9, 10 and 11 they have to click on the cog icon -> Print -> Page Setup, and activate the option)
You could have an own media-query for print and use :before selector with the attribute "content".
Put this in the media query and it will insert the image when you try to print:
p:before { content: url(images/quote.gif); }
http://www.htmldog.com/reference/cssproperties/content/
It's up to the user and their browser settings to print or not print background images. To keep yourself from relying on that, put the images directly in the HTML with an actual <img /> tag.
It is working in Google Chrome when you add the !important attribute to the background image. Make sure you add the attribute first and then try again, you can do it like this:
.class-name {
background: url('your-image.png') !important;
}
Also you can use these useful printing rules and put them at the end of css file:
#media print {
* {
-webkit-print-color-adjust: exact !important; /*Chrome, Safari */
color-adjust: exact !important; /*Firefox*/
}
}
Your main document, will import 2 stylesheets, 1 for the screen and another for the printer. You can fine tune the media settings as you need.
<!DOCTYPE html>
<html>
<head>
<link rel="stylesheet" type="text/css" href="screen.css" media="screen, print" />
<link rel="stylesheet" type="text/css" href="print.css" media="print" />
</head>
<body>
<div class="bg print"></div>
</body>
</html>
Here is the background image called in your main css file used in browsers.
.bg {
background: url("http://fpoimg.com/250x250") top left no-repeat;
width:250px;
height: 250px;
}
And your print hack used by browsers when users initiate the print dialog. So you can add the print class to your div and have it print out, or remove it if needed.
.bg.print {
display: list-item;
list-style-image: url("http://fpoimg.com/250x250");
list-style-position: inside;
}
Note: You can also use the #media rule instead of importing files if you want to avoid making an extra http request.
reference from: http://www.seifi.org/css/how-to-force-css-background-images-to-print-in-web-browsers.html
Try this:
#media print {
body:before {
content:url(http://192.168.0.11:8088/automation/img/mahyaA5.jpg);
position: absolute;
z-index: -1;
}
}
If you use Internet Explorer, this is how you do it:
Go to the 'Tools' menu.
Click on 'Internet Options'.
Click on the 'Advanced' tab.
Put a check on print background color and images.
<div style="position: relative;">
<img src="/images/blue.png" style="width: 100px; height: 100px;">
<div style="position: absolute; top: 0px; left: 0px;">
Hello, world.
</div>
</div>
This make sense of the CSS you posted, also see this website: https://defuse.ca/force-print-background.htm
set media="print"
<LINK REL="stylesheet" TYPE="text/css" MEDIA="print, handheld" HREF="foo.css">
Reference
When you are trying custom printing through creating print format directly with java script and if there is tag is there then it won’t be print because browser intensely send request to printer without waiting to load image in cache.
So good practice add image which you want to print on html page and make it visibility false.
I have a webpage that displays a web form whose source is javascript.
By default it places this form in the upper left corner of the screen. How to center it horizontally and vertically on the screen?
I'm confused because the block is in the <script> section rather than <body>.
The form is generated by my email marketing service provider, and I don't have access to its code.
The complete html file is:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="https://app...."></script>
</head>
<body>
</body>
</html>
Is it your javascript file or are you loading in an external file which creates the form? You can add classes/id's to javascript generated markup which is one way you could target it but you should be able to target and centre it just using:
form {display: block; margin: 0 auto; width: 100%}
Without actually seeing what your JavaScript is doing this is difficult to answer, however the generalized answer to your problem is to use CSS. You can do so within the head section of your html document using the <style> tag (see code below) or using <link> to add an external stylesheet.
Check out W3 to get you started learning more about CSS: http://www.w3schools.com/css/
Actual CSS attributes you will need may vary, but this article shows use of transform: translate to center an element vertically and horizontally.
<!DOCTYPE html>
<html>
<head>
<style>
/* this is a class you would add to the parent HTML tag of your form */
form {
position: relative;
left: 50%;
top: 50%;
transform: translate(-50%,-50%);
}
</style>
<script type="text/javascript" src="https://app...."></script>
</head>
<body>
</body>

I'm debugging a site on an Android HTC Sense. The site uses a lot of inserted content, which comes along with it's own CSS and JS like:
// wrapper id = snippet_id
<html>
<head>
<style type="text/css">
#snippet_id div {border: 1px solid red !important;}
div {border: 1px solid blue !important;}
</style>
</head>
<body>
<div>Hello World</div>
</body>
<html>
This is inserted into an existing page, so it sort these snippets are sort of like iFrames I guess.
Question:
Problem is, that while Javascript works fine, all CSS I'm specifying using <style> tags is being ignored. Any idea why?
EDIT:
Works on:
- Android 4.0.1
Does not work on:
- Android 2.3.1
- IOS 4.1
If I add the CSS to the main.css file being requested when the page loads, all is ok. If it's inside my gadget, it's not working.
EDIT:
So from what I can see, <style> does not seem to work on classes and id. If I use regular HTML elements as selectors it works.
EDIT:
My dev-site is here. I'm using a plugin called renderJs, which encapsultes HTML snippets (along with their CSS and JS) into resuable gadgets. Gadgets content will be appended to the page body, so although a gadget can act as a standalone HTML page, it can also be part of a page.
Example code from my page (I stripped out all gadgets but one below):
index.html - include index_wrapper gadget
<!DOCTYPE html>
<html itemscope itemtype="http://schema.org/Organization" lang="en" class="render">
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="../css/overrides.css">
<script data-main="../js/main.js" type="text/javascript" src="../js/libs/require/require.js"></script>
<title></title>
</head>
<body class="splash">
<div data-role="page" id="index">
<div id="index_wrapper" data-gadget="../gadgets/index_wrapper.html"></div>
</div>
</body>
</html>
The page has a gadget called index_wrapper link - code below:
<!DOCTYPE html>
<head></head>
<body>
<div id="index_social" data-gadget="../gadgets/social.html"></div>
<p class="mini t" data-i18n="gen.disclaimer"></p>
</body>
</html>
Which has another gadget called social here. This gadget includes some CSS, but on the devices in question, it is ignored (just saw, I'm missing a </div> in the index_wrapper, so trying to see if that fixed the problem, too).
The code below includes my fix:
<!DOCTYPE html>
<head>
<style type="text/css" scoped>
// will be ignroed
.el {width: 1px;}
.menu_social {text-align: center; margin: 1em 0;}
.action_menu {display: inline-block;}
.follow_us {display: inline-block; margin: 0; padding: 0 .5em 0 0;}
...
</head>
<body>
<div class="menu_social">
<div>
<span class="el ui-hidden-accessible"></span><!-- fallback for CSS not working -->
<div data-role="controlgroup" data-type="horizontal" data-theme="c" class="action_menu">
</div>
</div>
</div>
<script type="text/javascript">
//<![CDATA[
(function () {
$(document).ready(function() {
var gadget = RenderJs.getSelfGadget();
// fallback for old devices which cannot load <style> css
if (gadget.dom.find(".el").css('width') !== "1px") {
require(['text!../css/social.css'], function (t) {
var x = '<style>'+t+'</style>';
gadget.dom.append(x);
});
}
// trigger enhancement
$(this).trigger("render_enhance", {gadget: gadget.dom});
});
})();
//]]>
</script>
</body>
</html>
So aside from probably missing a closing </div> I'm still wondering why my embedded CSS is not working.
Looking at the generated HTML code (i.e., code as modified by JavaScript) of the demo page suggests that style elements are generated inside body. Although such elements are allowed by HTML5 drafts when the scoped attribute is present, support to that attribute seems to be nonexistent, and the style sheet is applied globally. It is possible however that some browsers do not apply it at all, at least when the style element is dynamically generated.
A better approach is to make all style sheets global to the document, preferably as external style sheets, and use contextual selectors to limit the rules to some elements only. And possibly using JavaScript to change classes of elements, rather than manipulating style sheets directly.
Ok. Ugly workaround:
In the inline section, set this:
<style>
.el {width: 1px;}
</style>
In the page, set hide an element el like this:
// ui-hidden-accessible is a JQM class, moving the item out of view
// since it uses pos:absolute, is needed to not break
// selects on the page (compare to JQM ui-icon)
<span class="el ui-hidden-accessible"> </span>
Then check for the width when running inline Javascript (which works) and require the inline CSS as a separate file, when the width is not at 1px
// fallback for old devices which cannot load <style> css
// gadget is my iframe-look-a-like
if (gadget.dom.find(".el").css('width') !== "1px") {
require(['text!../css/translate.css'], function (t) {
var x = '<style>'+t+'</style>';
gadget.dom.append(x);
});
}
Ugly and an extra HTTP request, but at least the CSS is working then.
