Just started with D3 and my HTML below is supposed to show vertical bars as per array (5 bars) but instead it only shows 3 bars.
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title></title>
<link rel="stylesheet" href="css/bootstrap.min.css"/>
<style type="text/css">
div.bar {
display: inline-block;
width: 20px;
height: 75px;
background-color: teal;
}
</style>
</head>
<body>
<nav class="navbar navbar-default navbar-fixed-top" role="navigation">
<div class="container">
<div class="navbar-header">
<button type="button" class="navbar-toggle collapse" data-toggle="collapse" data-target="#navbar"
aria-expanded="false" aria-controls="navbar">
<span class="sr-only">Toggle navigation</span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
<span class="icon-bar"></span>
</button>
<a class="navbar-brand" href="#">D3</a>
</div>
</div>
</nav>
<script type="text/javascript" src="js/d3.js"></script>
<script type="text/javascript">
var dataset = [5, 10, 15, 20, 25];
d3.select("body")
.selectAll("div")
.data(dataset)
.enter()
.append("div")
.attr("class", "bar");
</script>
</body>
</html>
However, if I move <script>...</script> before nav, I could see correct number of bars (5). For performance reasons I would like to maintain my original order and yet get it resolved. Any ideas?
In your current implementation, when you call selectAll("div"), the resulting selection contains the two <div> elements already present in the DOM (class container and class navbar-header). The first two data values (5 and 10) are associated with those two <div> elements. The remaining three data values (15, 20, and 25) are the only values in the enter() selection.
An easy fix would be to use selectAll("div.bar") instead, though you might want to re-read the D3.js documentation to better understand exactly why your original code is wrong.

I'm obviously doing something wrong but this is my Day 2 with Bootstrap. I have a fluid container with two rows. On the first row I've got a title and an image. That image - even though I reduced the height and have it set to responsive, causes that second column in the first row to basically extend to almost the whole page. When I remove the image, the world makes sense. When I put the image back, the container blows up. Happens with any image so it isn't the image, it is my bad bootstrap.

Tried using the thumbnail class, tried looking through Bootstrap docs, tried reordering to see if that helps. Did not help.
To fix these kinds of errors you need to learn how columns work in bootstrap:
You can read more about the columns here
The bootstrap columns are divided in this way, currently in your code you have entered only col which means they are columns that do not specify their size but fit the next columns;
Instead, in this example, the columns are expressed and you can command the display from mobile to desktop:

In this case I inserted two columns in the row, so that from mobile the view would be split in two and after the tablet (md) would display

I got help offline. The main issue isn’t with Bootstrap, but with how percentages work. I had the h-25 class on the element. The h-25 class attempts to set the height of an element to 25% of its parent. However, percentages only work properly when the parent has a well-defined/fixed height. When the parent doesn’t have a well-defined height, the browser enters a kind of feedback loop as it tries to adjust the set the height to a percentage while also adjusting the parent height to contain it.
Solutions
The easiest solution is to remove “h-25” and set a fixed height on the
Another option is to set a fixed height on the parent so that the percentage can be calculated definitively.
I went with the first option as putting a size on the image made it responsive where it doesn't overflow the container on smaller viewports.
I am using barryvdh/laravel-dompdf to generate pdf.
I'm trying generate one pdf file with multiple pages from data collection the problem is that I get only first element and one page. Using foreach loop to generate pages. Also I was trying to use foreach in my blade, but then I get only the last page.
Controller:
public function multiplePagesPdf(Request $request)
{
$kuponai = Kuponas::all();
//dd($kuponas);
$html = '';
foreach($kuponai as $kuponas)
{
$view = view('pdf.multiple')->with(compact('kuponas'));
$html .= $view->render();
}
$pdf = PDF::loadHTML($html);
$sheet = $pdf->setPaper('a4', 'landscape');
return $sheet->stream('sugeneruoti.pdf');
}
Maybe problem in my blade file:
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<title>Dovanų kuponas</title>
</head>
<body>
<div class="coupon">
<div class="page">
<div class="subpage">
<div class="container" style="
width: 21cm;
height: 16cm;
position: absolute;
top: 6.8cm;
font-family: DejaVu Sans;
background: white;
">
<h2>{{!! $kuponas->kupono_nr !!}}</h2>
<h3 style="margin-left: 3.2cm">
Dovanų kupono numeris:
<span style="color: black"></span>
</h3>
</div>
</div>
</div>
</div>
</body>
</html>
<style>
#page {
size: A4;
margin: 0;
}
#media print {
.page {
margin: 0;
border: initial;
border-radius: initial;
width: initial;
min-height: initial;
box-shadow: initial;
background: initial;
page-break-after: always;
}
}
</style>
There are certain things that are wrong in the code snippet you have provided, I will explain those first then provide correct way of doing it(for which I get results).
Firstly
you have used with & compact together, I don't know if it gets correct results but you should use any one of them or use array syntax of view method.
Secondly
what you are doing it you are rendering the view to html & then concating it, so , your html would look like,
<html>
.... content
</html>
<html>
.... content
</html>
& so on.
Thirdly
You css is messed up & not working as you want because of inline css you have added.
Solution
I would have used View Components to create similar views with different data.
So we would create a component in resources/views/components/single.blade.php (here I have named it single).
I have added your repeative code in the component single from your view. Now your coupon div class is in the component single.
<div class="coupon">
<div class="page">
<div class="subpage">
<div>
<h2>{{ $kuponas->kupono_nr }}</h2>
<h3>
Dovanų kupono numeris:
<span></span>
</h3>
</div>
</div>
</div>
</div>
Then in your view,
<!DOCTYPE html>
<html lang="en">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<head>
<title>Dovanų kuponas</title>
<style>
.page-break {
page-break-after: always;
}
</style>
</head>
<body>
#php $count = 0;#endphp
#foreach ($kuponai as $kuponas)
#php $count++ #endphp
<div class="container {{ (count($kuponai)-1 >= $count) ? 'page-break' : '' }}">
#component('pdf.components.single', ['kuponas' => $kuponas])
#endcomponent
</div>
#endforeach
</body>
</html>
use page-break class to create breaks, I have used count condition to remove one extra page break. I am passing the data of kuponas to the component.
Finally change your controller,
public function multiplePagesPdf(Request $request)
{
$kuponai = Kuponas::all();
//dd($kuponas);
$view = view('pdf.multiple', ['kuponai' => $kuponai]);
$html = $view->render();
$pdf = PDF::loadHTML($html)->setPaper('a4', 'landscape');
return $pdf->stream('sugeneruoti.pdf');
}
Here's what I got... for some reason when I click the image map links they open up the page outside the iframe (as in it opens up as it's own page)
I've messed with it for a couple hours and went through about 20 pages but none of them specifically deal with image map links and none of them are helping.
The live link is here, I'm using firefox.

ok... all that needed to happen was to add the name="content" attribute to the iframe so the image map links could target it
Instead of using the target attribute of the area tag, try using an onclick handler.
...
<area shape="contact" coords="801,9,981,42" href="#" onclick="loadNow('contact.html')" />
<area shape="about" coords="1020,9,1185,43" href="#" onclick="loadNow('about.html') />

function loadNow(url) { document.getElementById('content').src=url; }
I'm working on a microsite for a client, and things are working almost fine, except when I tried viewing it on firefox, I was surprised by how mis-placed things looked like..even though I disabled horizontal scrolling, in firefox u could still do it ( dont see the horizontal scroll but if you scroll horizontally it shows), even the webfont is different, although the webfont displays perfectly on firefox in other pages..and the third problem is the page top-margin, in the page properties I specified the margin to be 0 and in safari it worked, but in firefox it doesn't. could anyone please tell me what to do..I only have a spry menu bar and easing (animate2id) plugin which could be causing the problem maybe? in Safari it looks the way I want it to look..thanks in advance..
maybe I should mention that I'm a novice and I know what I know by self-learning.

I have been working on this for a bit and am not savvy enough to know how to correctly implement it (such that it remains a responsive design).
I am running the free "responsive" wordpress theme by ThemeID on a test site and need to have the main body content text of the single article page wrap underneath the right sidebar and adjust "dynamically" as the sidebar changes height over time. I plan on having the "Archives" widget in this right sidebar, so over time it will grow in height...so the body text should not extend to underneath the sidebar until it reaches the bottom of the sidebar. Take a look at a mockup I made real quick to demonstrate what I mean.
Before: http://www.heliossolutions.net/responsive.jpg
After 2: http://www.heliossolutions.net/responsive3.jpg
As you can see, the text currently leaves a huge white space beneath the sidebar but I would like for it to be able to flow underneath and adapt to the sidebar height. It also needs to maintain the responsive nature of the theme and work correctly on mobile devices (i.e. the sidebar widgets should properly display underneath all the content when viewed on a mobile phone, as it does out-of-the-box).
Does this make sense?
The page code currently looks like this:

[4/9/12 - Updated HTML code to show entire page, with extra Head info (javascript and style sheets) removed]
It's hard to tell because your HTML is not complete (most of the divs are not closed for example). However, both .widget-wrapper and .col-300 have bottom margins which if remove might do the trick.
