I need to overwrite some CSS in a Drupal back office (I can't change the CSS) and I tried to follow the instructions of this stackoverflow question.
So I made the following code :
EDIT
<style type="text/css">.maclasse div {
background: #ffffff;
overflow:auto;
width:auto;
}
.maclasse2 tbody tr td {
text-align: left;
}
</style>
And then, in the HTML I used my side classes :
<div class="maclasse maclasse2">
<table class="maclasse2">
<tbody>
<tr>
<td>
<pre style="margin: 0; line-height: 125%">
....
But it is not working ; the inspection of the page shows that :
In td, the text-align is still centered and we can see the override is denied. What do I need to add to my code ?
if just text in html like this code
<td class= "montd">
...
<span>text</span>
...
</td>
in css selected like this
.montd span {
text-align: left;
}
I'm attempting to make a printable stylesheet for our app but I'm having issues with background-color in #media print.
#media print {
#header{display:none;}
#adwrapper{display:none;}
td {
border-bottom: solid;
border-right: solid;
background-color: #c0c0c0;
}
}
Everything else works, I can modify the borders and such but background-color won't come through in the print. Now I understand that y'all might not be able to answer my question without more details. I was just curious if anyone had this issue, or something similar, before.
To enable background printing in Chrome:
body {
-webkit-print-color-adjust: exact !important;
}
Edit:
For Chrome, Safari and Firefox:
body{
-webkit-print-color-adjust:exact !important;
print-color-adjust:exact !important;
}
IF a user has "Print Background colours and images" turned off in their print settings, no CSS will override that, so always account for that. This is a default setting.
Once that is set so it will print background colours and images, what you have there will work.
It is found in different spots.
In IE9beta it's found in Print->Page Options under Paper options
In FireFox it's in Page Setup -> [Format & Options] Tab under Options.
Got it:
CSS:
box-shadow: inset 0 0 0 1000px gold;
Works for all boxes - including table cells !!!
(If the PDF-printer output file is to be believed..?)
Only tested in Chrome + Firefox on Ubuntu...
Try this, it worked for me on Google Chrome:
<style media="print" type="text/css">
.page {
background-color: white !important;
}
</style>
-webkit-print-color-adjust: exact; alone is Not enough
you have to use !important with the attribute
this is printing preview on chrome after I added !important to each background-color and color attrubute in each tag
and this is printing preview on chrome before adding !important
now, to know how to inject !important to div's style, check out this answer I'm unable to inject a style with an “!important” rule
Two solutions that work (on modern Chrome at least - haven't tested beyond):
!important right in the regular css declaration works (not even in the #media print)
Use svg
If you are looking to create "printer friendly" pages, I recommend adding "!important" to your #media print CSS. This encourages most browsers to print your background images, colors, etc.
EXAMPLES:
background:#3F6CAF url('example.png') no-repeat top left !important;
background-color: #3F6CAF !important;
There is another trick you can do without activating the print border option mentioned in other posts. Since borders are printed you can simulate solid background-colors with this hack:
.your-background:before {
content: '';
display: block;
position: absolute;
top: 0;
right: 0;
left: 0;
z-index: -1;
border-bottom: 1000px solid #eee; /* Make it fit your needs */
}
Activate it by adding the class to your element:
<table>
<tr>
<td class="your-background"> </td>
<td class="your-background"> </td>
<td class="your-background"> </td>
</tr>
</table>
Although this needs some extra code and some extra care to make background-colors visible, it is yet the only solution known to me.
Notice this hack won't work on elements other than display: block; or display: table-cell;, so for example <table class="your-background"> and <tr class="your-background"> won't work.
We use this to get background colors in all browsers (still, IE9+ required).
For chrome, I have used something like this and it worked out for me.
Within the body tag,
<body style="-webkit-print-color-adjust: exact;"> </body>
Or for a particular element, let's say if you have table and you want to fill a td i.e a cell,
<table><tr><td style="-webkit-print-color-adjust: exact;"></tr></table>
Despite !important usage being generally frowned upon, this is the offending code in bootstrap.css which prevents table rows from being printed with background-color.
.table td,
.table th {
background-color: #fff !important;
}
Let's assume you are trying to style the following HTML:
<table class="table">
<tr class="highlighted">
<td>Name</td>
<td>School</td>
<td>Height</td>
<td>Weight</td>
</tr>
</table>
To override this CSS, place the following (more specific) rule in your stylesheet:
#media print {
table tr.highlighted > td {
background-color: rgba(247, 202, 24, 0.3) !important;
}
}
This works because the rule is more specific than the bootstrap default.
I just added to the print media query this snippet and all style was applied as intended:
* {
color-adjust: exact!important;
-webkit-print-color-adjust: exact!important;
print-color-adjust: exact!important;
}
Found this issue, because I had a similar problem when trying to generate a PDF from a html output in Google Apps Script where background-colors are also not "printed".
The -webkit-print-color-adjust:exact; and !important solutions of course did not work, but the box-shadow: inset 0 0 0 1000px gold; did... great hack, thank you very much :)
Thought I'd add a recent and 2015 relevant aid from a recent print css experience.
Was able to print backgrounds and colors regardless of print dialog box settings.
To do this, I had to use a combination of !important & -webkit-print-color-adjust:exact !important to get background and colors to print properly.
Also, when declaring colors, I found the most stubborn areas needed a definition directly to your target. For example:
<div class="foo">
<p class="red">Some text</p>
</div>
And your CSS:
.red {color:red !important}
.foo {color:red !important} /* <-- This won't always paint the p */
Tested and Working over Chrome, Firefox, Opera and Edge by 2016/10. Should work on any browser and should always look as expected.
Ok, I did a little cross-browser experiment for printing background colors. Just copy, paste & enjoy!
Here it is a full printable HTML page for bootstrap:
<!DOCTYPE html>

for (i = 0; i < containers.length; i++)
{

container.insertAdjacentHTML('beforeend', '<canvas id="canvas-' + i + '"></canvas>');
// Color
var color = container.getAttribute("background-color");
container.style.backgroundColor = color;

var canvas = document.getElementById("canvas-" + i);
canvas.width = container.offsetWidth;
canvas.height = container.offsetHeight;
var ctx = canvas.getContext("2d");
ctx.fillStyle = color;
ctx.fillRect(0, 0, canvas.width, canvas.height);
}
window.print();

Best "solution" I have found is to provide a prominent "Print" button or link which pops up a small dialogue box explaining boldly, briefly and concisely that they need to adjust printer settings (with an ABC 123 bullet point instruction) to enable background and image printing. This has been very successful for me.
In some cases (blocks without any content, but with background) it can be overridden using borders, individually for every block.
For example:
.colored {
background: #000;
border: 1px solid #ccc;
width: 8px;
height: 8px;
}
#media print {
.colored div {
border: 4px solid #000;
width: 0;
height: 0;
}
}
* {
-webkit-print-color-adjust: exact;
}
Also, Enable > Emulate CSS Media From > Inspact > More Tools > Renders. Very detailed steps can be found here.
You can use the tag canvas and "draw" the background, which work on IE9, Gecko and Webkit.
If you don't mind using an image instead of a background color(or possibly an image with your background color) the solution below has worked for me in FireFox,Chrome and even IE without any over-rides. Set the image somewhere on the page and hide it until the user prints.
The html on the page with the background image
<img src="someImage.png" class="background-print-img">
The Css
.background-print-img{
display: none;
}
#media print{
.background-print-img{
background:red;
display: block;
width:100%;
height:100%;
position:absolute;
left:0;
top:0;
z-index:-10;
}
}
Do not set the background-color inside the print stylesheet. Just set the attribute in the normal css file and it works fine :)

My Content With Background!

Tested and works in Chrome and Firefox and Edge...
For some crazy reason my body tag is not working at all. It is the only CSS that isn't working. I am trying to have a background behind the content of my website and have the content be about 80% of the body. So that I can have two bars on either side of my website which kind of acts as a border. Kind of how there seems to be two white bars on either side of stack overflow.
<style type="text/css">
body{
font: 100%/1.4 Verdana, Arial, Helvetica, sans-serif;
background-color: #000;
margin: 0;
padding: 0;
color: #000;
}
#content {
font: 14px/1.4 'Times New Roman', sans-serif;
width: 80%;
max-width:1260px;
min-width: 780px;
background-color: #89837A;
margin-left: auto;
margin-right: auto;
}
Here is the HTML:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"

</body>
</html>
No matter what color I change the body tag to the background always stays white. The content is the correct color.
Don't put style link at the top of the some other link. that's why body design is not working. Put style link under the all the link
Is this: <style type="text/css"> in your CSS or is that just a mistake?
Unless that's an accident when your wrote that code, that's not valid CSS. The only time that's allowed is using the style tags within a HTML document to wrap CSS code.
Okay:
index.html
<style>
body {
background-color: white;
}
</style>
Not okay:
style.css
<style>
body {
background-color: white;
}
Since there's no closing tag, it looks like you accidentally copied that from a tutorial using the <style> tag inside a HTML document.
If you are using some kind of CSS framework make sure you place your custom CSS files, at last, the same thing happened with me I adjusted the order of the files that I
was including and it worked fine.
I don't know the exact reason why this problem is occurring.
The same problem has been occurred to me. However, I tackled it by using !important after the property in body in CSS file.
e.g. body{ background:black !important;}
If you found the actual reason do share it with me.
I know this was asked long ago but here is one solution. Put your css file link as the last one in the part of your html.
I know this was asked long ago, but I have just had the exact same issue.
Add a fake element style in your stylesheet before the body.
e.g.
#myFakeElement { color:red ; }
body{
font: 100%/1.4 Verdana, Arial, Helvetica, sans-serif;
background-color: #000;
margin: 0;
padding: 0;
color: #000;
}
Remove from the style sheet....
I just copied the code to my editor and it worked:
my problem is, that I have two different html files with a table containing theader, tfooter and tbody.
the first one is my own creation for test reasons and it looks like this:
<html>
<head>
<title>The Invoice</title>
<style type="text/css">
table.invoice { background-color: #dddddd; font-family: sans-serif; }
td, th { background-color: #ffffff; padding: 5pt; }
td.unit { text-align: right; }
td.price { text-align: right; }
thead { display: table-header-group; }
tfoot th { text-align: right; }
</style>
</head>
<body>
<div style="width:auto !important; overflow:hidden; position:relative">
<table class="invoice" cellspacing="1" cellpadding="0">
<thead>
<th>Unit</th>
<th>Description</th>
<th>Price</th>
</thead>
<tfoot>
<tr>
<th colspan="2">Sum</th>
<td class="price">1.230,32 EUR</td>
</tr>
</tfoot>
<tbody>
<tr><td>1</td><td>Excel</td><td >150,00 EUR</td></tr>
<tr><td>2</td><td>Document</td><td>150,00 EUR</td></tr>
... and so on ...
</tbody>
</table>
</div>
</body>
</html>
whenever I try the print preview on IE9 it shows the tfoot on the last page (page 5 in my case) which shows the overall sum of the body content price column.
when I try the same in Mozilla Firefox 11.0 it shows the tfoot with the overall sum on every page which I don't want of course.
the main reason I'm asking is because I have a FreeAgent html dom where I want to print out some Invoice. With that html file even IE9 shows the tfoot on every page, which, again!, I don't want.
I played around with
#media print { tfoot { display: table-footer-group;
position: absolute;
bottom: 0; }}
there it shows the footer just once, but on the first page at the bottom left all accross the rest of my text ...
ideas or solutions much appreciated! :)
Try this CSS in your print stylesheet, it will make the tfoot act as another row yet keeping the proper syntax that something like Datatables.net needs.
table tfoot{display:table-row-group;}
The tfoot is actually supposed to "always be visible at the bottom" (or something along those lines), so it makes sense for Firefox to print the footer at the bottom of the table on every page.
In particular this is useful for if you have table header cells to name columns, or are using the footer as a label or repeated headers.
You should probably have your sum as just another row on the end of the table.
I originally wanted to include a .css in my HTML doc that loads multiple other .css files in order to divide up some chunks of code for development purposes.
I have created a test page:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

#site_header {
background-color: #c0c0c0;
height: 100px;
position: absolute;
top: 100px;
width: 100%;
}
Problem:
When I use the above code, the site_header div does not have any formatting/background.
When I remove the link line from the HTML doc for site_header.css and instead use an #import url("/css/site_header.css"); in my main.css file, the same results -- nothing gets rendered for for the same div.
Now when I take the CSS markup from site_header.css and add it to main.css, the div gets rendered fine...
So I am wondering if having multiple css files is somehow not working... or maybe having that css markup at the end of my previous css is somehow conflicting, though I cannot find a reason why it would.
The #import directive has to come first in your CSS. As soon as one style is hit by the browser, all other import lines will be ignored.
To quote WC3:
"any #import rules must precede all
other rules (except the #charset rule,
if present)"
See http://www.w3.org/TR/CSS2/cascade.html#at-import
One thing to consider, is that each #import still causes an HTTP request, so it's not any more efficient than using multiple link tags. In fact it may be less efficient as imports may be sequential rather than parallel requests. See this article. IMO it also adds complexity because you end up managing CSS references in two places (head tag of markup plus 1 or more CSS files) vs a simple list of link tags.
I'd also recommend where you can combining CSS files when your site is in production as it will reduce HTTP overhead.
Can I just say, pet peeve here, but place images related to the CSS file in the CSS folder itself, not in /images/.
The point of CSS is the separation of style and content, and only content images should go in /images/. Any images called by the CSS should be placed in the same directory and called pathlessly, e.g.:
body {
background: url(wallpaper.png) repeat;
}
That way at a later date if it comes to changing the style, or making multiple styles it's just a case of updating one link and moving one folder (/css/) rather than having a mess of images scattered all over the filesystem. Plus it's always a bad idea to use absolute paths to files (such as /images/wallpaper.png).
First of all, you have invalid markup. The link tag must be closed...
<link rel="stylesheet" href="/css/main.css" />
Second, why don't you use double-quotes consistently for element attributes (here in the link tag you happen to use single-quote)? This is not part of the problem, but I find it daunting that you would intermingle various syntax conventions like this.
Lastly, I would not recommend using #import because it does not offer a compelling benefit. It must be the first thing in the CSS file. An additional HTTP request still has to be made for each of the additional CSS file(s). And on top of that, IE cokes when you to specify a target media for imports. I stick to the good old classic link tag because it just works (given that you have valid markup!).
Use firebug to inspect the div and see what styles are being applied to it, you might get some more insight.
use #import rule into your main.css file like:
#import url("css/site_header.css");(this code should be on top of your main.css)
the above import snippet will bind your multiple css files into single css
then that main.css file use into your HTML.
For any issues with CSS like this I would recommend using firebug. You will be able to see if your site_header.css is loading properly.
If it is loading you will be able to see which styles are being applied to which elements, perhaps some are being overwritten?
