D3 Elements are invisible despite existing in DOM - css

I have a bootstrap tab panel and I want to display a different d3 chart for each tab.
When the document loads, the first D3 chart is present in the DOM but its elements are invisible. Here's an example: http://i.imgur.com/7ATTyhI.png
Here is the setup for my tab pane in bootstrap:
<div role="tabpanel">
<!-- Nav tabs -->
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active"><a href="#ghg-co2" aria-controls="ghg-co2" role="tab" data-toggle="tab">
<h4>Change in CO<sub>2</sub></h4></a>
</li>
<li role="presentation"><a href="#ghg-ch4" aria-controls="ghg-ch4" role="tab" data-toggle="tab">
<h4>Change in CH4 (Methane)</h4></a>
</li>
<li role="presentation"><a href="#ghg-nos" aria-controls="ghg-nos" role="tab" data-toggle="tab">
<h4>Change in Nitrous Oxide</h4></a>
</li>
</ul>
<!-- Tab panes -->
<div class="tab-content">
<script src="js/ghg.js"></script>
<div role="tabpanel" class="tab-pane active fade fade-in" id="ghg-co2">
<div id="chart-ghg-co2" class="d3-chart"></div>
</div>
<div role="tabpanel" class="tab-pane fade fade-in" id="ghg-ch4">
<div id="chart-ghg-ch4" class="d3-chart"></div>
</div>
<div role="tabpanel" class="tab-pane fade fade-in" id="ghg-nos">
<div id="chart-ghg-nos" class="d3-chart"></div>
</div>
</div>
</div>
I have had issues with bootstrap displaying content in the tab pane correctly. I am using this hack in my style.css to override some bootstrap properties:
/* bootstrap hack: fix content width inside hidden tabs */
.tab-content > .tab-pane,
.pill-content > .pill-pane {
display: block; /* undo display:none */
height: 0; /* height:0 is also invisible */
overflow-y: hidden; /* no-overflow */
}
.tab-content > .active,
.pill-content > .active {
height: auto; /* let the content decide it */
} /* bootstrap hack end */
I got it from this thread
My D3 function is almost identical to this example: d3 scatterplot
but with different data.
At the bottom of my HTML, I have:
<script>
// Check if DOM is ready for D3
$( document ).ready(ghgco2()); // Names of my three D3 chart functions
$( document ).ready(ghgch4());
$( document ).ready(ghgnos());
</script>
I suspect the problem is that my d3 function, ghgco2() is attempting to render before the div in which it resides, .chart-ghg-co2 is ready. For some reason, the svg has the correct dimensions, and the elements are all present, but it's completely blank. This is resolved when I switch between tabs on the bootstrap pane.
Any and all help is appreciated.

What alternative is available to nth-child to select divs within other elements?

I have a HTML structure like so in my <nav>. I assumed nth-child was the way to go:
<nav>
<article class="menu-items">
<div class="row">
<ul class="col-6 column">
<!-- primary nav group one -->
<li class="primary-nav">Home</li>
<li class="primary-nav">News</li>
</ul>
<ul class="col-6 column right align-right">
<!-- primary nav group two -->
<li class="primary-nav">About</li>
<li class="primary-nav">Contact</li>
</ul>
</div>
<div class="row">
<!-- primary nav group three -->
<h1 class="primary-nav">Connect Online</h1>
<ul class="col-6 column submenu-items">
<li class="primary-nav">Twitter</li>
<li class="primary-nav">Instagram</li>
</ul>
<ul class="col-6 column right submenu-items align-right">
<!-- primary nav group four -->
<li class="primary-nav">Facebook</li>
<li class="primary-nav">Sq</li>
</ul>
</div>
</article>
</nav>
And some CSS to trigger a transform after a delay
.primary-nav:nth-child(n) {
transition-delay: 400ms;
}
.primary-nav:nth-child(2n) {
transition-delay: 400ms;
}
.primary-nav:nth-child(3n) {
transition-delay: 700ms;
}
.primary-nav:nth-child(4n) {
transition-delay: 700ms;
}
.primary-nav:nth-child(5n) {
transition-delay: 900ms;
}
/* and so on */
MDN: The :nth-child() CSS pseudo-class matches one or more elements based on their position among a group of siblings
I can't use nth-child here because primary-nav are among different groups. When the end of the first group is reached, it will restart over. Makes sense. (odd) or (even) won't be much use here either.
How can I taget each .primary-nav div here? Can I do it without JS?
I am not sure if its a suitable solution for you but I think you can do this with Jquery.
var navDivs = $(".your-class-name").find(".primary-nav"); //Gives the list of divs who have the class .primary-nav.
Or, you can give an id to your div and search by ID
var navDivs = $("#your-parent-div-id").find(".primary-nav"); //Gives the list of divs who have the class .primary-nav.
and finally by a for loop you can set any property of items by JQuery:
for (var i = 0; i < navDivs.length; i++) {
var div = navDivs[i];
$(div).css("your-css-property", "your-css-value");
}

Custom logo with link to homepage

I have a trouble to add custom logo with link to navbar if we scroll down
is class "dropdown-menu dropdown-inverse"
site: http://its-skin.upgates.com
CSS:
.secondlogo {
background-image: url(http://static.its-skin.upgates.com/m/m57daee4256187-sublogo.png);
width: 250px;
height: 54px;
margin-left: auto;
margin-right: auto;
}
here is the code full code :
<ul class="nav navbar-nav top-menu top-menu-categories">
{else}
<ul class="dropdown-menu dropdown-inverse" data-designer="d1-2-2-1">
{/if}
{foreach $tree as $category}
<li class="ct_{$category['category_id']} lev-{$level}{if $category['active']} active{/if}{if count($category['childs'])} dropdown{if $level > 1} dropdown-submenu{/if}{/if}" data-target-category="{$category['target_category_id']}">
<a href="{$category['url']}"{if $category["blank_yn"]} target="_blank"{/if} class="TopMenuLink">
{$category['name']}
{if (count($category['childs']))}
<i class="caret"></i>
{/if}
</a>
{if count($category['childs'])}
<button class="btn SubcategoriesLink"><i class="fa fa-chevron-right"></i></button>
{/if}
{include #desktopMenu tree => $category['childs'], level => $level + 1, option => false, colsCount => ceil(count($category['childs'])/$itemsInCol)}
</li>
{/foreach}
</ul>
You could add another list element at start of your ul which holds the link
<ul class="nav navbar-nav top-menu top-menu-categories">
<!-- New Element with class logolink -->
<li class="ct_29 lev-1 logolink">
<a href="http://its-skin.upgates.com/" class="TopMenuLink">
Link
</a>
</li>
<li class="ct_29 lev-1" data-target-category="29">
<a href="http://its-skin.upgates.com/krasa-it-s-skin" class="TopMenuLink">
Krása It's Skin
</a>
</li>
...
</ul>
Then just use css to put your logo in front of it
.logolink {
background-image: url(http://placehold.it/16x16/ff0000);
background-position: left center;
background-repeat: no-repeat;
padding-left: 20px; /* Adjust to your logo size*/
}
Example:
In case you want just a clickable logo image without text, wrap it inside the hyperlink <img src="#" /> and forget about the background-image in css.
EDIT:
If you want a fade-in effect when a user scrolls your page have a look at these two excellent jquery libraries which provide this functionality.
http://scrollmagic.io/
http://johnpolacek.github.io/scrollorama/
Alternative you can fade in with some jquery code. Therefore hide the logo (element) by setting it´s opacity to 0, detect the viewport scrolling and fade it in at some point. Find a working example here:

How to disable a nav-pill hover effect just in one item in the navbar with Bootstrap?

I would like to disable the nav-pill hover effect on just one item, the link that changes the language of the page, in my navbar. What is the best way to achieve this using either a bootstrap class or CSS?
<div id="navbarCollapse" class="collapse navbar-collapse">
<ul class="nav nav-pills navbar-right">
<li class="language language-active disabled">NL</li>
<li class="language language-nonactive language-right">EN</li>
<li class="approach-li">Diensten</li>
<li class="about-li">Over ons</li>
<li class="qa-li">Vragen</li>
<li class="about-li">Contact</li>
<li class="navbarpadding">
<form action="afspraak.html">
<button class="btn navbar-btn btn-primary2">Afspraak maken</button>
</form>
</li>
</ul>
</div>
Looking at your html using the class: ".language-nonactive"
You can these styles to go along with it, this will remove the hover of the grey background:
.nav>li.language-nonactive>a:hover, .nav>li.language-nonactive>a:focus {
background-color: transparent;
}
Here is a jsfiddle to show what I've done:
http://jsfiddle.net/ho1sgm1e/
Additionally you could you something like this with jquery:
$(document).ready(function() {
/*disable non active tabs*/
$('.nav li').not('.active').addClass('disabled');
/*to actually disable clicking the bootstrap tab, as noticed in comments by user3067524*/
$('.nav li').not('.active').find('a').removeAttr("data-toggle");
});
source: Bootstrap tabs pills disabling and with jQuery
Furthermore, utilising the disbaled class will effectively disable the button.
Using CSS:
.nav .language-nonactive a:hover {
background:rgba(0,0,0,0);
}

angular-bootstrap dropdown on mouseenter and keep dropdown-menu from hiding before being clicked.

First, I'm aware of this posts:
Activating bootstrap dropdown menu on hover
Bootstrap Dropdown with Hover
How to make twitter bootstrap menu dropdown on hover rather than click
And others, but still not found the correct solution yet, here's what I did so far.
first I used the is-open attribute from the angular-bootstrap dropdown directive like this:
<span class="dropdown" dropdown is-open="status.isopen">
<a
href
class="dropdown-toggle"
ng-mouseenter="status.isopen = true"
ng-mouseleave="status.isopen = false"
>
hover me for a dropdown with angular-bootstrap
</a>
<ul
class="dropdown-menu"
>
<li ng-repeat="choice in items">
<a href>{{choice}}</a>
</li>
</ul>
</span>
that seemed to work but 2 bugs appeared:
the first is when dropdown-toggle element is clicked the dropdown menu is gone clicking again wont bring it back you have to mouseleave then mouse enter the dropdown-tooggle to get the dropdown-menu back.
the second is a css/html problem.
Usually the regular css solution for a dropdown is like this:
<a class="css-dropdown">
hover here with css.
<div class="css-dropdown-menu">
<p>item 1</p>
<p>item 2</p>
<p>item 3</p>
</div>
</a>
Notice the dropdown-menu now is inside the dropdown-toggle element which mean when moving with the mouse from the dropdown-toggle to the dropdown-menu it's moving from parent to child, so basically we still hovering over the dropdown-toggle since we are in it's child, which mean the dropdown-menu will still be visible, on other hand, the bootstrap dropdown works with the click event so having the dropdown-menu as a child of the dropdown-toggle is not needed, but now when someone wants to change the behavior to mouseenter/hover once the mouse leaves the dropdown-toggle the dropdown-menu disappear so we no longer have access to the dropdown-menu elements this is visible in this plunker
To fix the first bug, I just removed the dropdown directive then replaced the is-open with ng-class directive like this.
Change this:
<span class="dropdown" dropdown is-open="status.isopen">
to this:
<span class="dropdown" ng-class="{'open': status.isopen}">
The rest stays the same plunker that fixed the first bug.
The second bug is tricky, since the dropdown-menu is no longer a child of the dropdown-toggle the hover effect wont last while moving from the toggle to the menu, so I did this.
Changed this:
<ul class="dropdown-menu">
to this:
<ul
class="dropdown-menu"
ng-mouseenter="status.isopen = true"
ng-mouseleave="status.isopen = false"
>
That did it but another bug appeared when clicking the dropdown-menu item it stays open, so I kept hacking by doing this.
changed this:
<li ng-repeat="choice in items">
to this:
<li ng-repeat="choice in items" ng-click="status.isopen = false">
That give me the required behavior plunker.
That said, this is not a good solution since a lot of directives are involved here for a simple visual effect, the last plunker I provided contains a css solution with no Bootstrap or AngularJS involved, though it is the required behavior it is not the required html structure or visual result, what I need is to have a space between the dropdown-toggle and the dropdown-menu not a padding of the toggle element just an empty space, which make the css solution not valid in this situation.
So, my question is there a better way of doing this without adding a new plugin/library more clean and easily reusable solution for the hover drop down menu?
First, have the toggling on the top-most parent element (in this case, the <span>)
<span class="btn-group" dropdown is-open="status.isopen" ng-mouseenter="status.isopen = true" ng-mouseleave="status.isopen = false">
<a class="btn btn-primary dropdown-toggle" dropdown-toggle>
Button dropdown <span class="caret"></span>
</a>
<ul class="dropdown-menu" role="menu">
<li>Action</li>
<li>Another action</li>
<li>Something else here</li>
<li class="divider"></li>
<li>Separated link</li>
</ul>
</span>
This will allow the behavior you wanted - while still allowing clicking to show/hide the menu ;-)
However there's an annoyance: if you move the mouse cursor slower and pass the small gap between the toggle and menu, it will hide the menu.
So secondly, add a small CSS to remove the gap
.dropdown-menu {
margin-top: 0;
}
See the action in this plunker.
I know you want a solution without adding a new plugin/library, but you (or others seeking for this behavior) might want to try using No Close from Dropdown Enhancements lib to keep the dropdown open even after clicking in one of its options:
Do not close the menu on click on radio add class .noclose.
<div class="btn-group">
<button data-toggle="dropdown" class="btn btn-default dropdown-toggle">
Checked option <span class="caret"></span>
</button>
<ul class="dropdown-menu noclose">
<li>
<input type="radio" id="gr1_1" name="gr1" value="1">
<label for="gr1_1">Option 1</label>
</li>
<li>
<input type="radio" id="gr1_2" name="gr1" value="2">
<label for="gr1_2">Option 2</label>
</li>
<li>
<input type="radio" id="gr1_3" name="gr1" value="3">
<label for="gr1_3">Option 3</label>
</li>
</ul>
</div>
Also add a CSS solution for the hovering problem:
.btn-group:hover .dropdown-menu.noclose {
display: block;
}
.dropdown-menu.noclose {
margin-top: 0px;
}
And, of course, don't forget to import the libs:
<script src="./js/dropdowns-enhancement.min.js"></script>
<link href="./css/dropdowns-enhancement.css" rel="stylesheet"\>
In your case I suggest you to study the Dropdown Enhancements's source code to see how it works and maybe find a more suitable solution.
Try adding this line to your css:
.btn-group:hover>.dropdown-menu { display: block; margin-top: 0; }
You'll have to remove your is-open, ng-mouseenter and ng-mouseleave directives.
Below is the solution I came up with, while working on the same issue.
I used a simple custom directive that:
binds the mouseenter and mouseleave events to the dropdown in order correctly to show/hide the menu.
dynamically adds a custom CSS class to the dropdown menu in order to prevent the menu from disappearing when moving the cursor from the button to the menu. Note that this solution has the advantage of not removing the visual gap between the button and menu.
prevents the menu from disappearing when the button is clicked.
The CSS rule uses a before pseudo-element to fill the gap between the button and the menu. I added the border property which can be uncommented to easily get a visual feedback.
.dropdown-hover-menu::before {
content: '';
position: absolute;
left: 0;
width: 100%;
top: -3px;
height: 3px;
/*border: 1px solid black;*/
}
The HTML structure of the snippet is based on the available examples in the dropdown section of the angular-ui bootstrap documentation
angular.module('app', ['ui.bootstrap'])
.directive('dropdownHover', function() {
return {
require: 'uibDropdown',
link: function(scope, element, attrs, dropdownCtrl) {
var menu = angular.element(element[0].querySelector('.dropdown-menu')),
button = angular.element(element[0].querySelector('.dropdown-toggle'));
menu.addClass('dropdown-hover-menu');
element.bind('mouseenter', onMouseenter);
element.bind('mouseleave', onMouseleave);
button.bind('click', onClick);
function openDropdown(open) {
scope.$apply(function() {
dropdownCtrl.toggle(open);
});
}
function onMouseenter(event) {
if (!element.hasClass('disabled') && !attrs.disabled) {
openDropdown(true);
}
};
function onMouseleave(event) {
openDropdown(false);
};
function onClick(event) {
event.stopPropagation();
}
scope.$on('$destroy', function() {
element.unbind('mouseenter', onMouseenter);
element.unbind('mouseleave', onMouseleave);
button.unbind('click', onClick);
});
}
};
});
.dropdown-hover-menu::before {
content: '';
position: absolute;
left: 0;
width: 100%;
top: -3px;
height: 3px;
/*border: 1px solid black;*/

CSS - Why IE6 doesn't follow this css rule li.class?

I am using the following rule to display a dot when the web is visited by a IE.
However, I don't know why the li.iedot doesn't work for IE6.0. In other words, all #nav-primary li displays the dot rather than #nav-primary li which has class .iedot.
#nav-primary li.iedot

1> How to fix it? Or IE just cannot do it.
2> Where I can find some website that indicates which css feature is supported by IE?
Thank you
Quirksmode by ppk is the place to learn about the browser inconsistencies.
Added: why it doesn't work --
I think the IE 6 bugs with elements that have multiple classes may be tripping you up.
Test this out by changing your html to be
<li class="iedot" id="nav-primary-home">
instead of
<li class="tab iedot" id="nav-primary-home">
If that's the problem, then you'll need to use only one class name in the element. You could either invent a bunch of new class names or add a wrap div/span with the iedot class.
