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:

(Did you see that? with the simple addition of the md class, but there are many others!)
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'm trying to include a letter head in my PDF templates like so:

Everything works fine when I put the header code in the template directly. But when I try to inlude it as a fragment, like above, I get the following Error:
org.thymeleaf.exceptions.TemplateInputException: An error happened during template parsing (template: "app/src/main/resources/template/pdf/fragments/header.html" - line 9, col 6)
template.html is in the app/src/main/resources/template/pdf/ folder. I had to include css and image files with the full path (from the root of the project) to get them to work. I tried including the fragment with the full path (as above) and only fragements/header, but I get the same error each time.
Im using
spring-boot-starter-thymeleaf 2.1.1
thymeleaf 3.0.11
Stacktrace:
[removed bc of character limit]
UPDATE
The correct path for the fragment is (in my case) "template/pfd/fragment/header" (so, full path from resources folder). Also, there was a typo in th:fragement="header".
The fragment reference should not be absolute to your project, but relative to your thymeleaf template root. So instead of (assuming it is app/src/main/resources/template/ whre your thymeleaf templates are located)
th:replace="app/src/main/resources/template/pdf/fragments/header ..."
use
th:replace="pdf/fragments/header ..."
The common use is
<div th:replace="fragments/header :: header"><div>
Using Thymeleaf
I've a simple main layout:
<!DOCTYPE html>
<html>
<head>
<title>Title</title>
#yield('style')
</head>
<body>
#include('layouts.frontend.partials.slider')
#yield('javascript')
</body>
</html>
layouts.frontend.partials.slider
#section('style')
<link rel="stylesheet" type="text/css" href="mystyle.css">
#append
#section('javascript')
<script></script>
#append
<div class="swiper-container">
<div class="swiper-wrapper">
<div class="swiper-slide" data-swiper-autoplay="1000">Slide 1</div>
<div class="swiper-slide" data-swiper-autoplay="1000">Slide 2</div>
<div class="swiper-slide" data-swiper-autoplay="1000">Slide 3</div>
</div>
<div class="swiper-pagination"> </div>
<div class="swiper-button-prev"> </div>
<div class="swiper-button-next"> </div>
</div>
The #section('style') will be ignored while the #section('javascript') is working fine within the include file...
I've reduced both files (main and include) to a minimum and swapped the position of style and javascript without any difference
What seems to be working is to change to position from the #yield('style') to the body, like:
<!DOCTYPE html>
<html>
<head>
<title>Title of the document</title>
</head>
<body>
#include('layouts.frontend.partials.slider')
#yield('javascript')
#yield('style')
</body>
Maybe it's not allowed to have #section in an include file?
What i want to archive is to have multiple partial includes with it's own css and javascript includes
Thanks
Here is another way to do, it's good because you have some flexibility.
You create a master template, put your main files
master.blade.php
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<link rel="stylesheet" href="">
#section('css')
<!-- some master css here -->
#show
</head>
<body>
#section('navbar')
#include('common.navbar')
#show
#yield('content')
#include('common.footer')
#section('js')
<!-- some js here -->
#show
</body>
</html>
The others childs extends the master, you'll have all your layout and can customize what you want:
Child blade
#extends('master')
#section('css')
#parent
<!-- more css -->
#endsection
#section('navbar')
#parent
#endsection
#section('content')
<!-- Main content goes here -->
#endsection
#section('js')
<!-- replace js and add my own -->
<!-- others js -->
#endsection
Did you try extending your child blade file to use the master template?
At the top of layouts.frontend.partials.slider did you put #extends('layout.master') (or whatever the path to your master template is?)
It could be an issue caused by the order in which you are including files. Wouldn't a simpler solution be to have a #yield('slider') in your master template and simply wrap the slider content in #section('slider') and drop the #include...?
I am new with bootstrap. I have the following problem with responsive image using bootstrap. My image doesn't seem to scale. I have no idea what might have gone wrong.
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, maximum-scale=1">
<link rel="stylesheet" href="bootstrap.min.css" />
</head>
<body>
<div class = "container">
<div class = "col-small-12">
<div class = "row">
<img src="images/web.png" class="img-responsive" alt="Responsive image">
</div>
</div>
</div>
</body>
Bootstrap's responsive image class sets max-width to 100%. This limits its size, but does not force it to stretch to fill parent elements larger than the image itself. You'd have to use the width attribute to force upscaling.

I'm currently building a page with jQuery mobile.
I need to load some custon JavaScript on one page, so I found the pageInit function.
Here's a short example of what i'm using:
page1.html:
<!doctype html>
<meta charset="uft-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>page1 | test page for jquery mobile</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css">
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
<script src="js.js"></script>
<div data-role="page" id="page1">
<div data-role="header">
<h1>Page 1 Title</h1>
</div>
<div data-role="content">
go to page2
<p>Page 1 content goes here.</p>
</div>
<div data-role="footer">
<h4>Page 1 Footer</h4>
</div>
</div>
page2.html:
<!doctype html>
<meta charset="uft-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>page1 | test page for jquery mobile</title>
<link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css">
<script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
<script src="js.js"></script>
<div data-role="page" id="page2">
<div data-role="header">
<h1>Page 2 Title</h1>
</div>
<div data-role="content">
go to page1
<p id="addstuff">Page 2 content goes here.</p>
</div>
<div data-role="footer">
<h4>Page 2 Footer</h4>
</div>
</div>
js.js
$(document).delegate('#page2', 'pageinit', function() {
$('<div />', {
html: 'Some text that was added via jQuery'
}).appendTo('#addstuff');
});
So I need to execute some JavaScript on page2.html. It actually works great (the div was created and you see the text). But when I'm clicking on a link to change the page, you can see, that jQuery is calling a hashtag in the URL first. So it looks like:
example.org/page1.html#/page2.html
when I clicked on the link on page1.html (just for a few milliseconds maybe) and then it redirects to
example.org/page2.html
I guess it's because of the id .. but I need this one for the pageInit (as far as I know).
Is this behavior normal ? Or am I doing something wrong. Maybe there's even a command to not call the hash tag.
Here you go:
It's important to note that if you are linking from a mobile page that was loaded via AJAX to a page that contains multiple internal pages, you need to add a rel="external" or data-ajax="false" to the link. This tells the framework to do a full page reload to clear out the AJAX hash in the URL. This is critical because AJAX pages use the hash (#) to track the AJAX history, while multiple internal pages use the hash to indicate internal pages so there will be conflicts in the hash between these two modes.
For example, a link to a page containing multiple internal pages would
look like this:
< a href="multipage.html" rel="external">Multi-page link< /a>

If you check the W3C documentation about Html5 you will find that you can have inside a a tag anything if it's not button or other links.
The a element may be wrapped around entire paragraphs, lists, tables, and so forth, even entire sections, so long as there is no interactive content within (e.g. buttons or other links).
