wicked_pdf (with wkhtmltopdf) not rendering correctly - html

I need to convert an existing html document to pdf. I use wicked_pdf for this task. But there are a lot of things which don’t render correctly:
hyphenation
rounded border on images
other stuff which I don’t care about that much at the moment
Hyphenation
When the pdf is created all paragraphs with hyphenation enabled are rendered without it. The CSS looks like this:
p {
margin-top : 0;
-webkit-hyphens : auto;
-moz-hyphens : auto;
-ms-hyphens : auto;
-o-hyphens : auto;
hyphens : auto;
hyphenate-limit-chars : auto 5;
hyphenate-limit-lines : 2;
widows: 3;
orphans: 3;
}
Rounded borders and images
I’ve got a container with rounded corners. Inside at the top of this container is an image displayed which should have rounded corners too. Unfortunately the image is rendered without rounded corners. It overlaps the container border which look pretty ugly.
The HAML for this container:
.profile-picture-container
= cl_image_tag #presenter.profile_picture, class: 'profile-picture'
.profile-picture-body
%p
= #presenter.user_fullname
And the corresponding CSS:
.profile-picture-container {
float : right;
margin-left : 5mm;
margin-right : -15mm;
border : 1px solid lightgray;
border-bottom-left-radius : 0.25rem;
border-bottom-right-radius : 0.25rem;
overflow : hidden;
}
.profile-picture-container, .profile-picture {
width : 50mm;
}
.profile-picture {
// -1px stolen from bootstrap’s definitions
border-top-left-radius : calc(0.25rem - 1px);
border-top-right-radius : calc(0.25rem - 1px);
}
.profile-picture-body {
padding : 3mm 5mm;
}
Other stuff not working correctly
Headings ignore their page-break-after: avoid; setting.
Is it just me or is html to pdf conversion not ready for primetime?

What happens when you have two media queries that are at the same size?

Lets you say you have two media queries on an element that both match. How do you know which one wins?
For example, let's say you have a media query that sets a rectangle to be red at LESS than or equal to 500 pixels and you a media query that makes it blue at MORE than or EQUAL to 500 pixels. Which one wins? And let's say you have a phone that is 500 pixels wide.
hr {
width: 400px;
left: 10px;
top: 0;
position: absolute;
}
.rect {
left: 10px;
position: absolute;
top: 20px;
right: 10px;
}
#media (max-width: 400px) {
.rect {
background-color: lightgray;
}
}
/* larger content */
#media (min-width: 400px) {
.rect {
background-color: lightblue;
}
}
<div class="rect">
Here is a div
</div>
<hr width="500px">
I would like to setup proper media break points. Do I need to rewrite them? Should they be min-width 501px and so on?
Normally it's the style declaration that comes last in the code that "wins" (is applied!). You can set !important on a style declaration, but IMHO that is toss-up and sometimes doesn't work. I 'think' id styles will have more importance over class styles, but I do know you can set multiple class name styles more influential.
Code not tested:
#less_important {
background : green;
width : 50px;
height : 50px;
}
.blue {
background : blue;
width : 50px;
height : 50px;
}
.red {
background : red;
border : 1px solid yellow;
}
<html>
<div id = "less_important" class = "blue">
</div>
<div class = "blue red">
</div>
<div class = "red blue">
</div>
</html>
Move the style .red and .blue in the code and see what happens to understand
CSS mean Cascading Style Sheets.
Definition of cascade:
"Something arranged or occurring in a series or in a succession of stages so that each stage derives from or acts upon the product of the preceding."
So, whatever comes after in the cascade will overwrite the previous.
Yes, you should set the one with min-width to 401.

styled div lines disappear for print screen [duplicate]

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!

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 :)

Content width changed by invisible scrollbar

NOTE : The name of the post is what I suppose is happening... It can be edited later if someone find a better short description
> What am I trying to do ?
I'm trying to hide a scroll bar by adding padding on the right side of the scrollable element.
This element contains child elements (list or table)
> What problems are you facing ?
The width of the child element should be 100% of the containing element, but obviously it's less.
The empty space on the right looks like it's the scrollbar place.
So my questions are :
Why is that happening ?
How can I get the childElement (.inner*) to fit in the ContentBox of its parent ?

PS: I put some CSS properties apart (end of CSS section) because I don't think they have anything to do with this problem and seems mandatory for me to get the expected result
♥
I found a way to solve my problem by adding some Javascript. If someone has a pure CSS solution, I would like to see it.
Here is the Javascript added :
function removeScrollBar() {
$(".container").each(function() {
var iWidth = $(this).width();
var child = $(this).find(".innerTable, .innerContent");
child.css('width',iWidth);
});
}
$(function() {
removeScrollBar();
});

Whole code : http://jsfiddle.net/o3omng/Vh3u9/
<div id="as_profile" class="div_clearboth"></div>
<div id="as_notice" class="div_clearboth"></div>
In the HTML code, #as_profile and #as_notice are
both have class="div_clearboth" attribute.
.div_clearboth { clear : both ;
margin-bottom : 10px ; }
In the CSS code,
I give clear:both style and margin-bottom : 10px style to div_clearboth attribute.
It works well in other div tags,
but It doesn't work well in #as_profile.
Check the jsfiddle. Then you can see that there is no space between #as_profile and #as_notice.
They must be 10px away. How can I fix it?

<s_somethig> tag and [##something##] are going to replace by server automatically.
You can correct it by giving #as_profile an overflow value besides visible:
#profile_control {
overflow: hidden;
}
Or changing display to inline block:
#profile_control {
display: inline-block;
}
Or giving it padding/border:
#profile_control {
padding: 1px 0 0 0;
}
As #sevenseacat pointed out, the culprit is the floated li's within #as_profile
CSS :
#as_profile {
padding-bottom:20px;
}
Can you use Padding for divide? It works for me.
