I get the arrow when there is no scrollbar but it goes away when I add scroll bar to the popover content.
I couldn't get it running on jsfiddle. So i am posting the code here.
CSS
.pop-div .popover {
max-width: 310px;
height: 250px;
overflow-y:scroll;
}
HTML
<li>
<div class="pop-div">
<a href="#" id="myid" rel="popover" >click me</a>
</div>
</li>
JAVASCRIPT
$("a[rel=popover]").click(function(e) {
e.preventDefault();
$.ajax({
url: '/myurl',
success: function(data) {
$("#myid").popover({
placement: 'top',
title:'title',
html:true,
content:data
});
}
});
});
That's because the arrow is supposed to appear below the popover but since you are telling it to scroll vertically, it can't "get out" of the parent. I suggest you use the .popover-content class provided by Bootstrap to enable scrolling on the inner content only
CSS
.pop-div .popover-content {
max-width: 310px;
height: 250px;
overflow-y:scroll;
}
Demo fiddle
I added overflow:auto to the popover-content and max-width:100% to popover it works well for me
.popover .popover-content {
overflow: auto;
}

I am working on a popup window using ngDialog. Here is some code:
<style>
.ngdialog.dialogforpopup .ngdialog-content
{
width : 1100px;
margin-top:-100px;
padding-top:10px;
}
</style>
Template
<div style="height:800px;width:1040px;padding-left:5px;padding-top:5px;
padding-right:5px"
</div>
<div class="ngdialog-buttons" style="margin-top:10px">
<button type="button" class="ngdialog-button ngdialog-button-primary"
ng-click="cancel()">Cancel</button>
<button type="button" class="ngdialog-button ngdialog-button-primary"
ng-click="save()">Save</button>
</div>
Directive
ngDialog.open({
template: 'editor.html',
controller: 'editorController',
className: 'ngdialog-theme-default dialogforpopup',
closeByDocument: false,
disableAnimation: true
});
I have two questions.
How can center my popup on the screen? Currently I am using margin-top:-100px;
Is it possible to size ngDialog automatically to its content?
Thanks
One can center ngdialog by setting "table-like" styles:
.ngdialog{
padding:0 !important;
}
.ngdialog-content {
padding: 0 !important;
background: transparent !important;
display: table; /*table-like styles for vertical centering*/
width: 100% !important;
height:100%;
}
.ngdialog-holder {
display: table-cell;
vertical-align: middle;
width: 100%;
height:100%;
}
.ngdialog-content > .ngdialog-close{
display:none; /*hide original close button*/
}
.my-dialog{
width:400px;
background:#fff;
border:1px solid #000;
margin:0 auto; /*center dialog horizontally*/
position: relative;
}
Also one need to wrap content of dialog with ".ngdialog-holder" and ".my-dialog" blocks. And finally place ".ngdialog-close" button inside of it.
<div class="ngdialog-holder">
<div class="my-dialog">
Dialog content goes here
<div class="ngdialog-close"></div>
</div>
</div>
Here is live example: ngdialog plunk
I downloaded ngDialog package using bower. so ngDilaog related CSS and JS files are in bower_components.
I added the following CSS and JS files to my html page.
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog.css">
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog-theme-default.css">
<link rel="stylesheet" href="../bower_components/ng-dialog/css/ngDialog-theme-plain.css">
<script src="../bower_components/ng-dialog/js/ngDialog.js"></script>
In my own JS file I am opening the dialog in the following way:
ngDialog.open({ template : 'dialog' ,scope : $scope , className: 'ngdialog-theme-default', plain: false,
showClose: true,
closeByDocument: true,
closeByEscape: true,
appendTo: false});
here is the html code:
<script type="text/ng-template" id='dialog'>
<div class="ngdialog-message">
Hello!!
</div>
</script>
With the above changes I am able to show the pop up on the center of the screen.
can use of the following class for pop up.
className: 'ngdialog-theme-plain'
className: 'ngdialog-theme-default'
I hope this will help!
I wan't to make a special menu for the iPad version of my website.
It should work like this:
http://itu.dk/people/mbul/humlum/images/ipad_menu.png
Click on IMG 1 and the menu expands (to IMG 2) and the links gets visible. When you click outside IMG 2 it disappears along with the links so only IMG 1 is visible.
I've come this far but it doesn't really do the trick:
<div class="nav_mobile_container">
<div class="nav_mobile_elements">
<div class="nav_mobile"></div>
</div>
</div>
div.nav_mobile_container{
position: fixed;
top: 0px;
left: 0px;
}
div.nav_mobile_elements{
display: inline-block;
}
div.nav_mobile_elements a{
vertical-align: top;
display: inline-block;}
div.nav_bookmark:hover{
display: inline-block;
}
.nav_mobile{
width:70px;
height:70px;
background-image:url('images/menu_small.png');
display: inline-block;
}
.nav_mobile:hover{
width:496px;
height:500px;
background-image:url('images/menu_small_expanded.png');
}
I would really appreciate a CSS solution on this if possible.
Thank you!
The closest you can get is
#nav_mobile:active {
width:496px;
height:500px;
background-image:url('images/menu_small_expanded.png');
}
But that does not work on an ipad.
I recommend to use a bit of javascript.
Create an onclick event that displays a div with all the navigation information you need.
With jquery:
$("#small_navigation").click(function(){
$("#big_navigation").show();
});
The css:
#big_navigation {
display: none;
width: ...
height: ...
etc...
}
You will need javascript for this. Using jQuery, this is how you could make it :
First, don't set an :hover in your CSS, but just make a class that you will add on click :
.nav_mobile.navopen {
width:496px;
height:500px;
background-image:url('images/menu_small_expanded.png');
}
And then a bit of jQuery to make it work :
$(document).ready(function(){
// expend the menu on click
$('.nav_mobile').on('click', function(event){
event.stopPropagation();
$(this).addClass('navopen');
});
// close menu on click outside the menu
$('html').click(function() {
$('.nav_mobile').removeClass('navopen');
});
});
The jsFiddle demo
Edit : with pure javascript
window.onload = function() {
var menu = document.getElementsByClassName('nav_mobile')[0];
menu.onclick=function(e){
e.stopPropagation();
menu.className = "nav_mobile navopen";
};
var html = document.getElementsByTagName('html')[0];
html.onclick=function(){
menu.className = "nav_mobile";
};
};
I found a good lightbox effect on a blog but I'm not sure how to tweak it the way I need. Aside from manipulating background opacity and z-index, it works by setting a divs css display property to "none" and then "block" when the effect is triggered. In that div I have the unordered lists I apply the jquery menu() and dialog() methods to. The lightbox effect and the ui methods work, but the dialog won't open inside the div designated by the class: "white content". It opens behind the white content instead. I tried to change the z-index of the dialog() in my script, but it didn't work. below I have the code from my .css, .html and .js files.
CSS
/*Lightbox effect
----------------------------------*/
.black_overlay {
display: none;
position: absolute;
top: 0%;
left: 0%;
width: 100%;
height: 2000%;
background-color: black;
z-index:1001;
-moz-opacity: 0.8;
opacity:.80;
filter: alpha(opacity=80);
}
.white_content {
display: none;
position: absolute;
top: 25%;
left: 25%;
width: 50%;
height: 100%;
background-color: white;
z-index:1002;
overflow: auto;
}
HTML
<body>
<div id="light" class="white_content">
<div id="dialog" title="Invite">
<ul class="menu">
<li>
Age Group
<ul>
<li name="ageGroup">18-21</li>
<li name="ageGroup">21-30</li>
<li name="ageGroup">30-40</li>
<li name="ageGroup">40-50</li>
<li name="ageGroup">50-60</li>
<li name="ageGroup">60-70</li>

<li name="ageGroup">80-90</li>
<li name="ageGroup">90-100</li>
</ul>
</li>
</ul>
<button>Button label</button>
</div>
</div>
<div id="fade" class="black_overlay"></div>
</body>
JS
$(function(){
//event handler that triggers lightbox effect
$('#list').on('click', '.edit', function(event){
//this is where the lightbox effect executes.
$("#light").css("display", "block");
$("#fade").css("display", "block");
//I want the dialog and menu to open inside of the div #light
$("#dialog").dialog();
$(".menu").menu();// closes $("menu").menu()
$( "button" ).button();
}//closes function(event)
);// closes on()
}); //closes $function.
I couldn't find a way to get a UI dialog to open inside a <div>. Might be that it is made purposely to always open as a child of <body>. In jQuery UI site the dialog runs inside a <iframe> so that might trick you to believe it's inside a <div>.
My suggestion would be to put jQuery UI components inside your lightbox as it is already kind of like a dialog. Also if you want your lightbox to move you should be good with jQuery UI's draggable and resizable.
Here's a jsFiddle I made to explain what I'm after.
The bootstrap documentation on that topic is a little confusing to me. I want to achieve similar behaviour like in the docs with the affix navbar: The navbar is below a paragraph / page heading, and upon scrolling down it should first scroll along until reaching the top of the page, and then stick there fixed for further scrolldowns.
As jsFiddle does not work with the navbar concept, I've set up a separate page for usage as a minimal example: http://i08fs1.ira.uka.de/~s_drr/navbar.html
I use this as my navbar:
<div class="navbar affix-top" data-spy="affix" data-offset-top="50">
<div class="navbar-inner">
<div class="container">
<div class="span12">
<a class="brand" href="#">My Brand</a>
This is my navbar.
</div>
</div> <!-- container -->
</div> <!-- navbar-inner -->
</div> <!-- navbar -->
I thinkg i would want data-offset-top to be of value 0 (since the bar should "stick" to the very top" but with 50 there is at least some effect watchable.
If also put the javascript code in place:
<script>
$(document).ready (function (){
$(".navbar").affix ();
});
</script>
Any help appreciated.
I was having a similar problem, and I believe I found an improved solution.
Don't bother specifying data-offset-top in your HTML. Instead, specify it when you call .affix():
$('#nav').affix({
offset: { top: $('#nav').offset().top }
});
The advantage here is that you can change the layout of your site without needing to update the data-offset-top attribute. Since this uses the actual computed position of the element, it also prevents inconsistencies with browsers that render the element at a slightly different position.
You will still need to clamp the element to the top with CSS. Furthermore, I had to set width: 100% on the nav element since .nav elements with position: fixed misbehave for some reason:
#nav.affix {
position: fixed;
top: 0px;
width: 100%;
}
One last thing: When an affixed element becomes fixed, its element no longer takes up space on the page, resulting in the elements below it to "jump". To prevent this ugliness, I wrap the navbar in a div whose height I set to be equal to the navbar at runtime:
<div id="nav-wrapper">
<div id="nav" class="navbar">
<!-- ... -->
</div>
</div>
.
$('#nav-wrapper').height($("#nav").height());
Here's the obligatory jsFiddle to see it in action.
Just implemented this for the first time, and here's what I've found.
The data-offset-top value is the amount of pixels that you must scroll in order for the affixing effect to take place. In your case, once 50px is scrolled, the class on your item is changed from .affix-top to .affix. You'd probably want to set data-offset-top to about 130px in your use case.
Once this class change occurs, you must position your element in css by styling the positioning for class .affix. Bootstrap 2.1 already defines .affix as position: fixed; so all you need to do is add your own position values.
Example:
.affix {
position: fixed;
top: 20px;
left: 0px;
}
To fix this very issue I have modified the affix plugin to emit a jQuery event when an object is affixed or unaffixed.
Here is the pull request: https://github.com/twitter/bootstrap/pull/4712
And the code: https://github.com/corbinu/bootstrap/blob/master/js/bootstrap-affix.js
And then do this to attach the navbar:
<script type="text/javascript">
$(function(){
$('#navbar').on('affixed', function () {
$('#navbar').addClass('navbar-fixed-top')
});
$('#navbar').on('unaffixed', function () {
$('#navbar').removeClass('navbar-fixed-top')
});
});
</script>
You need to remove .affix() from your script.
Bootstrap gives the option of accomplishing things either via data-attributes or straight JavaScript most of the time.
I've got this from the twitterbootstrap's source code and it's working pretty well:
HTML:
<div class="row">
<div class="span3 bs-docs-sidebar">
<ul id="navbar" class="nav nav-list bs-docs-sidenav">
...
</ul>
</div>
</div>
CSS:
.bs-docs-sidenav {
max-height: 340px;
overflow-y: scroll;
}
.affix {
position: fixed;
top: 50px;
width: 240px;
}
JS:
$(document).ready(function(){
var $window = $(window);
setTimeout(function () {
$('.bs-docs-sidenav').affix({
offset: {
top: function (){
return $window.width() <= 980 ? 290 : 210
}
}
})
}, 100);
});
You just need to remove the script. Here is my example:
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="http://code.jquery.com/jquery-1.8.0.min.js"></script>
<script type="text/javascript" src="http://netdna.bootstrapcdn.com/twitter-bootstrap/2.1.0/js/bootstrap.min.js"></script>
<style>
#content {
width: 800px;
height: 2000px;
background: #f5f5f5;
margin: 0 auto;
}
.menu {
background: #ccc;
width: 200px;
height: 400px;
float: left;
}
.affix {
position: fixed;
top: 20px;
left: auto;
right: auto;
}
</style>
</head>
<body>
<div id="content">
<div style="height: 200px"></div>
<div class="affix-top" data-spy="affix" data-offset-top="180">
<div class="menu">AFFIX BAR</div>
</div>
</div>
</body>
</html>
Thanks to namuol and Dave Kiss for the solution.
In my case I had a tiny problem with navbar height and width when I used afflix and collapse plugins together. The problem with width can be easily solved inheriting it from parent element (container in my case). Also I could manage to make it collapsing smoothly with a bit of javascript (coffeescript actually). The trick is to set wrapper height to auto before collapse toggle occurs and fix it back after.
Markup (haml):
#wrapper
#navbar.navbar
.navbar-inner
%a.btn.btn-navbar.btn-collapse
%span.icon-bar
%span.icon-bar
%span.icon-bar
#menu.nav-collapse
-# Menu goes here
CSS:
#wrapper {
width: inherit;
}
#navbar {
&.affix {
top: 0;
width: inherit;
}
}
Coffeescript:
class Navigation
#initialize: ->
#navbar = $('#navbar')
#menu = $('#menu')
#wrapper = $('#wrapper')
#navbar.affix({offset: #navbar.position()})
#adjustWrapperHeight(#navbar.height())
#navbar.find('a.btn-collapse').on 'click', () => #collapse()
#menu.on 'shown', () => #adjustWrapperHeight(#navbar.height())
#menu.on 'hidden', () => #adjustWrapperHeight(#navbar.height())
#collapse: ->
#adjustWrapperHeight("auto")
#menu.collapse('toggle')
#adjustWrapperHeight: (height) ->
#wrapper.css("height", height)
$ ->
Navigation.initialize()
My solution for attach the navbar :
function affixnolag(){
$navbar = $('#navbar');
if($navbar.length < 1)
return false;
h_obj = $navbar.height();
$navbar
.on('affixed', function(){
$navbar.after('<div id="nvfix_tmp" style="height:'+h_obj+'px">');
})
.on('unaffixed', function(){
if($('#nvfix_tmp').length > 0)
$('#nvfix_tmp').remove();
});
}
Similar to the accepted answer, you can also do something like the following to do everything in one go:
$('#nav').affix({
offset: { top: $('#nav').offset().top }
}).wrap(function() {
return $('<div></div>', {
height: $(this).outerHeight()
});
});
This not only invokes the affix plugin, but will also wrap the affixed element in a div which will maintian the original height of the navbar.
Is it possible to center an image only trough setting a class to the img tag without side effects? The problem is the following: I have an anchor around an image. If I use the following CSS
.aligncenter {
clear: both;
display: block;
margin-left: auto;
margin-right: auto;
}
And this (stripped down) HTML:
<a href="/path/to/image.jpg" class="fancybox" rel="fancybox" title="System">
<img src="/path/to/image.jpg" title="System" class="aligncenter">
</a>
the link takes the whole width of the main div. This means not only the image is clickable - also the space around the image (actually the whole width) is clickable. This is through the CSS display: block.
How can I center an image without using a parent div? I don't want the whole area clickable.
Background:
You can read this topic. It is about Wordpress and the built in editor. He automatically generates the class aligncenter on an image (if the user pressed the center button). I need this for my own theme. According to the moderators there this should be only a CSS question and doesn't have to do with changing code in Wordpress.
in aligncenter class add text-align:center
.aligncenter {
clear: both;
display: block;
margin-left: auto;
margin-right: auto;
text-align:center;
}
I'm not familiar with wordpress, but you might want to try setting the image's and the anchors's css 'display' property to 'inline-block'.
If you are limited in changing the document's DOM, another option is adding an 'onClick' attribute to the image.
This will allow you to run some function once the image is clicked.
So, for example, if you want to redirect to another page:
<img src='myImg.png' onclick='myRedirect()' style='cursor:pointer'/>
And in the page's header:
<script type='text/JavaScript'>
var myRedirect = function(){
window.location.href = 'Some other location';
}
</script>
Notice the style='cursor:pointer', which changes the mouse's cursor to a 'hand' cursor.
To avoid an additional div container or even JavaScript, you can make the anchor display as a block:
.logo {display: block; height: 115px; margin: 0 auto; width: 115px;}
/* height and width must equal your image's values */
<img src="logo.png" alt="Logo" />
Live demo: http://jsfiddle.net/performancecode/Ggk8v/
it still incorporates a div, but the way i do it is:
<div class="megaman">
<img src="img/megaman.jpg" alt="megaman">
</div>
img {
height: 125px;
width: 200px;
}
.megaman{
text-align: center;
margin: 0 auto;
display: block;
}
And yes, I replaced .logo with .megaman because megaman rocks! But it should work. I couldn't figure it out without using a div.
The solution I found. Adding /></a> and width and height to the anchor tag cuts down the hyperlink to the image...
<a class="link" href="URL" target="_blank"> <img width="75px" height="75px" alt="Facebook" src="IMAGE LOCATION"/></a>
Second answer:
paste this in functions.php
add_filter('image_send_to_editor','give_linked_images_class',10,8);
function give_linked_images_class($html, $id, $caption, $title, $align, $url, $size, $alt = '' ) {
// only do this on center
if($align == 'center') {
$html = str_replace('aligncenter', '', $html);
$html = '<p style="width: 100%; text-align: center;" >'.$html.'</p>';
}
return $html;
}
Down side, this won't effect already inserted images...
Also if you can please move the style of the <p> to the stylesheet.
