angularJS ng-animate with animate.css - css

How do I get ng-animate to work with animate.css on simple html elements like images paragraphs or divs?
In a static page I just include the animate.css and wow.js libraries and add a couple classes to the element I want to animate. But I have been unsuccessful in getting it to work inside ng-view.
<img class="wow fadeInLeft" src="http://images.ximo365.com/nick-olsen-pose.jpg" alt="Nick Olsen On-the-go shots">

In Angular 1.2+, you don't need to declare the ng-animate directive in your application module. Animations can be added with pure CSS.
First, you need to include the angular-animate library in addition to angular:
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.0-beta.1/angular.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.0-beta.1/angular-animate.js"></script>
You need to set the conditions for ng-animate on your element.
For your image elements:
<img src='../img/img1.jpg' ng-animate="{enter: 'animate-enter', leave: 'animate-leave'}" class=">
You also need to include the CSS for the actions you want, so for your example:
.animate-enter,
.animate-leave
{
-webkit-transition: fadeInLeft 1s;
position: relative;
display: block;
// Etc.
}
The animate will fire when the element enters. If you want to load it on page load, that will take more work. If you want to load it when the element is shown, you should use something like ng-repeat, so that when the item is displayed, it will fade-in.
See the nganimate.org docs

Changing body css from within an Angular component

Angular4
Hi All. I'm have a single page within a large Angular4 app that needs to have body css that's different to the rest of the app.
I don't want to set ViewEncapsulation.None because it's just the one component that needs to be affected.
Can I use :host(), :host-context() or ::ng-deep in some way to select the body and apply the css rules? If so then how please? If not, is there another way to achieve this?
Thanks!
Thank you both very much. #Palpatine1991, you asked why I would want to access the <body> DOM element. This is because I have one page in the app which is a full screen game that is played on mobile devices and has drag and drop functionality within it. On iOS the "bounce" effect present in Safari makes drag and drop a very poor experience. So I wanted to add the following css to the body and html DOM elements of that single page, which suppresses that bounce effect.:
html,
body {
height: 100%;
width: 100%;
overflow: auto;
}
I had a look into the solutions you gave (thank you!) and went with the following solution:
ngOnInit() {
this.renderer2.addClass(document.body.parentElement, 'wholeClassGameBody_student');
this.renderer2.addClass(document.body, 'wholeClassGameBody_student');
}
ngOnDestroy() {
this.renderer2.removeClass(document.body.parentElement, 'wholeClassGameBody_student');
this.renderer2.removeClass(document.body, 'wholeClassGameBody_student');
}
This seems to work.
Thank you :)
Why do you need to add your CSS to <body> if it affects only one component?
Using :host() it will apply the styles to the element which is selected by component's selector.
Using ::ng-deep you can select only elements which are somewhere under the host element (but <body> is not under your host!)
The only way how to change the styles of the body from the component which has ViewEncapsulation.Emulated is using the Renderer2 API but it seems to me like a very bad practice
If you need to override some global <body> styling of your component, you can do it using :host-context. Example here: https://stackblitz.com/edit/angular-material2-issue-oodjmm

Can i apply an external css file only to a div and its children?

I don't think it is possible, but I will ask anyway:
Can I apply an external css file (Bootstrap for instance) to a div and its children without affecting the rest of the page.
For example, I need to migrate a footer written with Bootstrap over to an existing page. That page does not use bootstrap. If I link Bootstraps css at the top of the page, the css is applied to the whole page which ruins existing css. How can I just apply the bootstrap styles to the footer section without having to rewrite most of the page's css?
Any suggestions?
I ended up using LESS to compile a new css of bootstrap with a prefix of .bootstrap as seen below. It works, but i wonder if there is a more traditional way of handling this problem.
file: bootstrap-only.less
.bootstrap {
#import 'bootstrap.css'
}
file: bootstrap-only.css
.bootstrap .container {
width: 100%;
}
file: page.html
<style>
.container { width: 20px; }
</style>
<link rel="stylesheet" type="text/css" href="bootstrap-only.css">
<div class="not-bootstrap">
<div class="container">I am 20px</div>
</div>
<div class="bootstrap">
<div class="container">I am 100%</div>
</div>
You can try usig scooped css.Please do refer the following sample code.
<div>
<style scoped>
#import "filename.css";
</style>
//your div with its children will come here
</div>
Your inline styles should not be affected by adding Bootstrap as inline styles take precedence over styles from external resources. The only elements that should be affected are the ones in the page that share class names with bootstrap classes.
You can try referencing the Bootstrap css before your own css and your stylesheet will take precedence over the Bootstrap css. Unfortunately this may add styles additional styles to some of your classes which that you didn't explicitly reference in your stylesheet and may still change the look of your page.
For those classes that exist in both bootstrap and your stylesheet it's probably best to just change the names of those classes in your stylesheet and page. A quick way to do this is to use "replace" search for the class name and replace it with the new class name most IDEs have a way to "replace all" so it's often just a bit of typing and a few clicks to change a bunch of styles.
You can try using the Angular 2+, where you can simply create an component and us it anywhere irrespective of the page css. Basically it will create a shadow DOM and will not be accessible outside that component.

How to use scrollRevealJS alongside AnimateCSS?

I love both the scrollRevealJS and AnimateCSS libraries for animations, however, I would like to use them both on one element. For example, I have a div <div class="animated fadeInDown" data-sr='enter top reset'>Lorem Ipsum</div>. For some reason, adding the Animate CSS classes animated fadeInDown ignores scrollReveal's data attribute. How am I able to use both the classes and data attributes of both libraries?
EDIT: I forgot to mention that I have the following style applied:
[data-sr] { visibility: hidden; }
The ScrollRevealJS library does not provide default functionality to work with AnimateCss. Instead of ScrollRevealJS you can use Wow.js library – it works with AnimateCss. The problem with Wow.js is that a reset option is not available.

customizing the drop down autocomplete box

I'm using jquerys autocomplete widget but I'm having a few issues trying to style the box that drop down when you search for something.
I'm trying to move the box down a bit and change the border/bg color but some JS is adding in some embedded styles which are overriding my .css styles. But I can't find it.
I'v based mine off this one.
<ul class="ui-autocomplete ui-menu ui-widget-content" role="listbox" aria-activedescendant="ui-active-menuitem" style="z-index: 11; display: block; width: 139px; top: 44px; left: 1101px; "><li class="ui-menu-item" role="menuitem">
In order to avoid using !important you could add your styles with jQuery and override them in that way.
$('ul.ui-autocomplete').css({
color: 'red'
});
Another solution would be to remove the style attribute from the ul.
$('ul.ui-autocomplete').removeAttr('style');
Without seeing your css styles, or the order you are loading the .css files, you could override the styles by using Firebug to inspect which classes are applied, and adding !important; to your main css styles.
Ex.
ul.ui-autocomplete {
color: red !important;
}
The best way you can combat this is to properly track down if your jQuery plugin has any parameters to help you, or strip the JS yourself and add your own CSS styles.
The above !important; rule can be a nightmare, it is a hack in a sense - but it may work for you.
Try to add margin-top and margin-left in your css
Overriding the top and left value is no good, because it is calculated in regard to the text field it derives from.
I'm really not a pro in jquery but I take a look around in the example you sent and the style of the menu is all givent by a menu style sheet (jquery.ui.menu.css). Look at the link below and there is some info that can help you I think.
http://docs.jquery.com/UI/Menu#theming
You will be able to customize the look and feel of your dropdown in these class.
«If a deeper level of customization is needed, there are widget-specific classes referenced within the jquery.ui.menu.css stylesheet that can be modified.» From jquery website.
try using position or append to option...
you can refer here...
http://jqueryui.com/demos/autocomplete/#option-position
Check out the file jquery.ui.theme.css,
the class .ui-widget-content near the top can be used to put a background colour on the autocomplete search results box, borders and positioning can also be tweaked through this class.
